I want to call a method in a foreign class (eg ClassA). How do I create an instance of this class?

It depends on whether the method is a static or instance method. You might want to check out Sun's java tutorial first to refine your question a little bit.

Typically you create instances of a class by calling its constructor using the new operator:

There are situations, though, where you are not allowed to do this (that is, there is no public constructor to call), so you have to call another method to get an instance of the class.
Did that help?

A simple example of creating an instance of a class and invoking an instance method:Sun's basic J2SE tutorial is located at http://java.sun.com/docs/books/tutorial/
