The easiest way to describe a java bean is that it is a class file that has a bunch of fields i.e. private int foo and then it has getter and setter methods to access these private fields, this would be something like public int getFoo() { return foo; } and public void setFoo (int foo) { this.foo = foo; } and they would be there for all of the fields.

Getters/Setters are used to expose access to private member variables.

Here's an example of a getter/setter for foo in your class above:

Code:

---

public int getFoo()
{
  return this.foo;
}
public void setFoo(int newfoo)
{
  this.foo = newfoo;
}

---

The primary use of getters and setters is data validation.

A Java bean is well more than a simple struct-style element. It is really meant to allow you to write a piece of code once, and run it everywhere (applets, desktop apps, JSP, etc). Basically let's say you have a class that deals with outputting customer data. You might have this class written once but be using it on your secured site via JSP, in a desktop Java app, or in a Java applet served from the web.

The FAQ for Java Beans is here: http://java.sun.com/products/javabea...q.general.html

A better term than getters/setters is accessors (getters) or mutators (setters). And a java bean is not a struct. It may be better to compare then to a com component.

Thanks guys.
Actually i am sorry for not thanking earlier.
But the help you guys offered was really helpfull, it did solve the purpose.
