Why main method is static?

Why the main () method in Java is always static? Java main() method is always static, so that compiler can call it without the creation of an object or before the creation of an object of the class. In any Java program, the main() method is the starting point from where compiler starts program execution.

Does return type matter in method overloading?

Return type does not matter while overloading a method. We just need to ensure there is no ambiguity! The only way Java can know which method to call is by differentiating the types of the argument list.

Why return type is not in method overloading?

Overloading is the mechanism of binding the method call with the method body dynamically based on the parameters passed to the method call. ... It is not possible to decide to execute which method based on the return type, therefore, overloading is not possible just by changing the return type of the method.
