In a class,

Overloaded Method having same name but different parameters or  Overloaded methods will have same name but different number of arguments or different types of arguments.


  • Can we declare one overloaded method as static and another one as non-static?

  • Is it possible to have two methods in a single class with same method signature but different return types?

No     compiler will give duplicate method error
