Hello, Through reflection you can do activity at runtime or examine the exceutting java programm.

Class c = Class.forName("MyClass"); Method m = c.getDeclaredMethods(); for (int i = 0; i < m.length; i++) System.out.println(m[i].toString()); //It will give you all //methods declared in MyClass } Thanks

It is a powerful approach to analyze the class at runtime.It allows programmatic access to information about the fields, methods and constructors of loaded classes, and the use reflected fields, methods, and constructors to operate on their underlying counterparts on objects, within security restrictions.
