Java: Summary: Methods

Parameters

Method parameters are separated by commas. Parameters are converted to these larger or equal types (int, long, double).

main

If you have a main method, it must be declared

   public static void main(String[] args)

signature

To decide which method to call, Java looks at the method signature (method name, type and order of the parameters). The signature of the caller and celled method must match. The signature does not include the return type, or parameter names.

return

If a method does not return a value, there is no need for a return statement. If a method returns a non-void value, it must use a return statement.
