Can be put two main method in the same class in java if yes than give the example?

It's possible to place multiple main() methods in the same class in the following ways:

1. By overloading the main() method so that each overload takes different types and/or numbers of parameters .

2. By placing an additional main() method, or overloads thereof, within a nested class of the class which contains the main() method.

Though why you'd want to do that, other than as an exercise, I cannot imagine.
