I don't know much about java but I'm pretty sure the answer depends on what you want the java to do.

I don't see how that changes my point.

This still doesn't tell what you want to do through Java.

For example in java class:-

public class Add
{
   public int addition (int a , int b)
   {
            return(a+b);
  }
}

I want to call this java class from my Oracle forms. In Forms I have two input and one output field and one ADD button. on ADD button i want to call java class which is responsible for return the addition.

Please help me out .

Using Java to perform a simple calculation doesn't make any sense. There is no need to use Java for something PL/SQL can do for you without the overhead of the Javabean.

Now, if you want to extend Forms functionality by changing the look and feel of a Form - then using a Javabean in your Form would be the way to go. If you wanted to subscribe to some type of web service and display the output of that web service in a Form, then using a Javabean in your Form would be the way to go. If you want to use Java to perform some type of process that stores the result in a table or causes some other action to be scheduled in the Database, then using Java in the database would be the way to go.

A simple Internet search on "Examples of using Java with Oracle database" or "Examples of using Java with Oracle Forms" would have given you some ideas of how and when you should use Java with Oracle.
