In Java it is possible to define  two or more methods within the same class that share the same name, as long as their parameter declarations are different.

When this is the case, the methods are said to be overloaded, and the process is referred to as method overloading.

Method overloading is one of the ways that Java supports polymorphism.

When an overloaded method is invoked, Java uses the type and/or number of arguments as its guide to determine which version of the overloaded method  to actually call. Thus, overloaded methods must differ in the type and/or number of their parameters.  While overloaded methods may have different return types, the return type alone is insufficient to distinguish two versions of a method. When Java encounters a call to an overloaded method, it
simply executes the version of the method whose parameters match the arguments used in the call.
