HiThis will clarifies your doubt. I think so.

When To Use Interfaces
An interface allows somebody to start from scratch
to implement your interface or implement your interface
in some other code whose original or primary purpose was quite different from
your interface. To them, your interface
is only incidental, something that have to add on to the their code to be able
to use your package.
When To Use Abstract classes
An abstract class, in contrast, provides more
structure. It usually defines some default implementations and provides some
tools useful for a full implementation. The catch is, code using it must
use your class as the base. That may be highly inconvenient if the other
programmers wanting to use your package have already developed their own class
hierarchy independently. In Java, a class can inherit from only one base class.
When to Use Both
You can offer the best of both worlds, an interface
and an abstract class. Implementors can ignore your abstract
class if they choose. The only drawback of doing that is calling methods via
their interface name is slightly slower than
calling them via their abstract class name.

Venkat

Hi guys,
 
 
The importance of Load-on-startup is
if we want to call the servet while STARTIING  the server that will be mapped
to the load-on-startup
in the load-on-startup we can set the priority levels,
if we have more then one servet to be called
 
i.e
 
<LOAD-ON-STARTUP>1<LOAD-ON-STARTUP>
TELLS THE PRIORITY LEVEL IS FIRST

1)In a class i have 10 variables... out of them i want to serialize

only 3 variables..how to do it?

you have to implement serializable interface and you have to declare variables
as transient which are not supposed to serialize.

2)In a class i have 2 methods.Each is associated with 2 threads (t1

for method1,t2 for method2).Both the methods r synchronized. .Now if i

call both the methods...will they execute simultaneously or not?

please explain?

it may lead to deadlock.

3)What is permanent generation ofJVM?

4)What is ORM file?

Object Relation Mapping in heard that it is used in Spring Frame work.

5)What is the default value in <load-on-startup> tag...what is the

difference among 0,1,2,3 etc...?

6)How people r saying that vector is a legacy class..what' s the logic

behind?

Vector is legacy class means it was built before the collection framework cames
without any synchronization. The Vector and Hashtable both are legacy class.
Which are implemented before Collection Framework is implemented.

7)How to synchronize a class?

8)Is an Action class itself is Servlet or not?

9)What is difference b/w Class Variables and Instance

Variables..and. .how can i find whether a variable is a CV r IV just by

looking at them in a class?

Class variables are declared as static with static keyword.
others are instance variables if they are not declared in method.

10)Which method will be called first in a Form-bean class?

Dear sirisha,
 
Marker interface is also called as tagged interface and it doesn't contain any
methods but we can provide a class which is implementing this tagged
interface.And tagged interfaces are used to make a class some meaningful by
implementing this tagged interface.
For Ex. if u went to purchase T-Shirt, on T-Shirt u can find a tag which
exhibits its rate,cloth type,size etc i.e it provides the information regarding
the T-Shirt in the same way tagged interface provides some information to the
class which is implementing it.
 
any class implementing tagged interface(Serializable) java understood that this
class is serializable class

The Name

The Java- prefix suggests that JavaScript is somehow related to Java,
   that it is a subset or less capable version of Java. It seems that the name
   was intentionally selected to create confusion, and from confusion comes
misunderstanding.
   JavaScript is not interpreted Java. Java is interpreted Java. JavaScript is
   a different language.

JavaScript has a syntactic similarity to Java, much as Java has to
C. But it is no more a subset of Java than Java is a subset of C. It
is better than Java in the applications that Java (fka Oak)
was originally intended for.

JavaScript was not developed at Sun Microsystems, the home of
Java. JavaScript was developed at Netscape. It was originally called
LiveScript, but that name wasn't confusing enough.

The -Script suffix suggests that it is not a real programming language,
   that a scripting language is less than a programming language. But it is
really
   a matter of specialization. Compared to C, JavaScript trades performance for
   expressive power and dynamism.

Lisp in C's Clothing

JavaScript's C-like syntax, including curly braces and the
clunky for statement, makes it appear to be an ordinary
procedural language. This is misleading because JavaScript has more
in common with functional languages like Lisp or Scheme  than with C or Java.
It has arrays instead of lists and objects instead of property
lists. Functions are first class. It has closures.
You get lambdas without having to balance all those parens.

Typecasting

JavaScript was designed to run in Netscape Navigator. Its success there led
   to it becoming standard equipment in virtually all web browsers. This has
resulted
   in typecasting. JavaScript is the
   George Reeves of programming languages. JavaScript is well suited to a large
   class of non-Web-related applications

Moving Target

The first versions of JavaScript were quite weak. They lacked
exception handling, inner functions, and inheritance. In its present
form, it is now a complete object-oriented programming language. But
many opinions of the language are based on its immature forms.

The ECMA committee that has stewardship over the language is
developing extensions which, while well intentioned, will aggravate
one of the language's biggest problems: There are already too many
versions. This creates confusion.

Design Errors

No programming language is perfect. JavaScript has its share of design errors,
   such as the overloading of  +  to mean both addition and concatenation
   with type coercion, and the error-prone with statement should be avoided.
   The reserved word policies are much too strict. Semicolon insertion was a huge
   mistake, as was the notation for literal regular expressions. These mistakes
   have led to programming errors, and called the design of the language as a
whole
   into question. Fortunately, many of these problems can be mitigated with a
good
   lint
   program.

The design of the language on the whole is quite sound.
Surprisingly, the ECMAScript committee does not appear to be
interested in correcting these problems. Perhaps they are
more interested in making new ones.

Lousy Implementations

Some of the earlier implementations of JavaScript were quite buggy. This
reflected
   badly on the language. Compounding that, those implementations were embedded
   in horribly buggy web browsers.

Bad Books

Nearly all of the books about JavaScript are quite awful. They contain errors,
   poor examples, and promote bad practices. Important features of the language
   are often explained poorly, or left out entirely. I have reviewed dozens of
   JavaScript books, and I can only recommend one: JavaScript:
   The Definitive Guide (5th Edition) by David Flanagan. (Attention authors:
   If you have written a good one, please send me a review copy.)

Substandard Standard

The official
   specification for the language is published by ECMA.
   The specification is of extremely poor quality. It is difficult to read and
   very difficult to understand. This has been a contributor to the Bad Book
problem
   because authors have been unable to use the standard document to improve their
   own understanding of the language. ECMA and the TC39 committee should be
deeply
   embarrassed.

Amateurs

Most of the people writing in JavaScript are not programmers. They
lack the training and discipline to write good programs. JavaScript
has so much expressive power that they are able to do useful things
in it, anyway. This has given JavaScript a reputation of being
strictly for the amateurs, that it is not suitable for professional
programming. This is simply not the case.

Object-Oriented

Is JavaScript object-oriented? It has objects which can contain
data and methods that act upon that data. Objects can contain other
objects. It does not have classes, but it does have constructors
which do what classes do, including acting as containers for class
variables and methods. It does not have class-oriented inheritance,
but it does have prototype-oriented inheritance.

The two main ways of building up object systems are by inheritance
(is-a) and by aggregation (has-a). JavaScript does both, but its
dynamic nature allows it to excel at aggregation.

Some argue that JavaScript is not truly object oriented because it
does not provide information hiding. That is, objects cannot have
private variables and private methods: All members are public.

But it turns out
that JavaScript
objects can have private variables and private methods. (Click here now
to find out how.)  Of course, few understand this because JavaScript is
the world's most misunderstood programming language.
Some argue that JavaScript is not truly object oriented because it does not
   provide inheritance. But it turns out that JavaScript
   supports not only classical inheritance, but other code reuse patterns as
well.

1. It doesn't matter what data store type you use.

One of the first steps in designing an application is to decide on
the data store. It used to be that every application was based upon a
database, and this was simply not an issue. However, there has recently
been an upsurge in additional options: you can now use relational
databases, XML databases, object databases, directory servers, and more.




Instead of this approach, it is possible to devise a method where
your own beans handle this numbering. By putting the code into your
beans, and removing it from the vendor-domain, you suddenly are back to
vendor-neutrality, flexibility, and even (in many cases) better
performance. If you check out my book, I'll give you the exact
code to handle this specific case, and show you in detail how to avoid
these vendor-specific problems.

3. I need an editor or tool to write my Enterprise JavaBeans.

I'm often asked about the tools that I use in my EJBs. Specifically,
people want to know what I use to generate my remote interface, home
interface, and implementation-class source code. The idea is that there
is so much repeated code in these components that you have to have a
tool in order to make things easier. The mistake creeps in when you go
in and modify these skeletons, and miss a spot here, or accidentally
foul up a method signature there. The result is code that fails
compilation and is often hard to debug.

Now maybe it's just that I cut my teeth on Java using vi and
notepad, but I'm content with Ctrl+C and Ctrl+V, and 'yy', 'dd', and
'p'. Cutting and pasting in these text editors has kept me much better
off than any editor or tool ever has. It also generally results in me
understanding my code better, and knowing exactly where everything in
my code is.

I'm not saying that you shouldn't use an editor or a tool (I often use jEdit.);
however, as soon as you depend
on those tools, you're in trouble. Take a week to code in nothing but a
text editor, and you'll be amazed at how reacquainted you manage to get
with your code. Of course, my book assumes no such tools, and it walks
you through the exact process that results in efficient, logical coding
of beans, as well as other components in your application.

4. I've got to include JMS, XML, JAXP, and more in every application.

I realize that if you¢ve been reading my books and articles for very
long, you¢re probably tired of this sort of thing. I'm constantly
harping on programmers, insisting that they only use what they need in
their programs. However, until I see people get over their
technology-lust, I'll keep hollering about this one.

The basic mistake I'm referring to is the thinking that everything
in J2EE must be used in a J2EE application. If that application doesn't
use EJBs, JMS, JMX, XML, and every other acronym on the package of your
application server, you think you're somehow wasting money.

Nothing could be further from the truth, though. In fact, in my
latest book, I had to almost force in a chapter on JMS (the Java
Message Service). This isn't because JMS isn't important; it's simply
that the application I was writing for the book didn't really need JMS
that much. I have written several applications that do use JMS, and I
was able to come up with a pretty good use-case for JMS in the book.
However, that situation is a perfect illustration of the issue:
sometimes you just don't need the whole kitchen sink.

In any case, for about the 50th time, you should only use what you
need. If all that is required is a couple of servlets and some JDBC
code, then stick with that; don't add the complexity of EJBs if you
don't need it. If you need EJBs, but message-driven beans are beyond
the scope of your application, don't worry about it. In the long run,
you'll appreciate the resulting simplicity of your application.

5. Stateful beans make programming more object-oriented.

This is a common one, and usually an easy one to correct. The basic
mistake involves the way that methods are called. For example, here's a
few methods that you might find in a stateful session bean's remote
interface:

     public User create(String username);
   public Address getAddress();
   public List getAccounts();
   public boolean deleteAccount(Account account);

The thinking is that you need to make this a stateful session bean so that you
can pass in the username only one time (in the create() method). So your method
calls would look like this:

     User user = userHome.create(username);
   Address address = user.getAddress();
   List accounts = user.getAccounts();

This is more object-oriented than using a stateful bean, which has methods more
like this:

     public User create();
   public Address getAddress(String username);
   public List getAccounts(String username);
   public boolean deleteAccount(String username, Account account);

The result is that the same code block would look like this:

User user = userHome.create();
Address address = user.getAddress(username);
List accounts = user.getAccounts(username);

Wow! It's obvious that this is so much harder to understand
and work with. (OK, that was a bit sarcastic; print is such a hard
medium to get clever in.) As you can see, this may not be quite as OO
(object-oriented). However, you'll find that changing to the stateless
approach (shown second) results in a speed up to the tune of 10 times
or sometimes even 100 times faster (depending on the application
server). So for this rather small sacrifice in OO coding results in
your code speeding up dramatically. One more mistake dealt with and out
of the way.

6. I don't need anyone telling me what to do in my programming.

Ah, yes. We've all been there, right? I remember my first few years of
programming when I knew
that I was going to always innovate, always create, never copy, and
never need any help. Of course, I later found out that most of my
clever "innovations" were poor solutions to well-understood problems,
many with established "best-case" solutions. It's absurd to be so
egotistical as to refuse to accept help when it's offered.

Is this a shameless plug for my book? No, not really. I'd advise you
to go out and get anything you can find on the subjects you are working
in. Heck, I have nearly as many non-O'Reilly technical books as I do
O'Reilly books, and I use my whole library all the time.

I'd also recommend you get involved in the open source community.
You'll learn more than you could ever imagine. The bottom line is that
there are a lot of really bright people out there, and I'd suggest you
suck all the knowledge from these folks that you can. As soon as you
decide that you don't need anyone else's help, you'll certainly begin
to make more mistakes than ever.

Well, there are six common problems I see cropping up time and time
again. You may see one or two in this list that you yourself have
ascribed to. Don't feel embarrassed; I've been guilty of all of these
at one time or another, but I got over it. Just take them as spurs to
make you a better programmer. I hope you enjoy the new book, and I look
forward to hearing what you think. See you online!

The only drawback of doing that is calling methods via

Actually,what do you want to know?

use BufferedReader and InputStream Reader

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

br.readLine()

hi,

hidden form field and URL Rewriting are Session Tracking Techniques
if Cookies are disabled on browser the alternative is URL Rewriting.

1) on first page in html form
    you can add like this

    <input type="hidden" name="TransId" value" " >

    value can be assigned from any script or directly.

then this values are send in a request object like other elements
so you can retrieve in other page.

2)URL Rewriting is modifying every url with unique session id

u can use two classes URLEncoder of java.net class or
servlet api method response.encodeURL(String).

when using above method for url that will modified with jsessionid.

HttpSession internally uses Cookies /URL Rewriting.

krishna kumar.(KK)

Read the tutorials at java.sun.com . There is a printf () equivalent in
Java; scanf is a different story, and you may have to get creative.

There is no such thing as a pointer in Java. Primitives are stored by
value, and Objects are stored by reference. So, your scanf () would have
to only accept Objects, as they can be changed by the caller, but
primitives could not be passed.

HI ,
   Generally interfaces  contains abstract methods,but marker interfaces does
not.Marker interface means its just mark the classes which implement marker
interface to be serializable.Means JVM understand that class object state to be
written to persistent storage.

An interface cannot define any methods (only declare them).  An abstract

class can't be instantiated itself, but it can define concrete methods

that can be used in subclasses.

I just want to ask, what does "<Something>" do in the code?
What do you call that thing?

if there's somebody out there who can help by  giving links to reading
materials or ideas related to my query,or other better explanation of
that, then i will greatly appreciate it.

thanks

As I know we can increase the visibility of super class method in our overrided
sub class method.
 
If super calss have public method, and subclass have the overrided protected
method of that super class' method.So what will be the problem over this
scenario. please clarify me..

Hi All,

I am new to this group.

I have a problem. I need to construct an XML with the contents of a
database row, But the XML should be less than 500MB. The select query
returns 100 rows and each row contains a BLOB field. Is there any way
to calculate the size of a row in bytes?

Waiting for your help. Thanks in advance.

Best Regards,
Ashly.

I guess you are asking why you can't do this:  The answer is because protected
has weaker
access than public.
