Method Overloading

The operation decisions in method overloading are decided during compilation time whenever static binding is in action. Polymorphism is accommodative to method overloading because of multiplicity of definitions relative to the interfaces for message channeling and implementations. Overloading prevails when a method accepts multiple variables with shared identities but varying parameters. A method that houses multiple identical definitions is equally capable of executing the underlying varying parameters of the definitions.

The sources of multiple definitions with identical names would usually be instructions that are conveyed to the method. For example, an instruction to create a contact in a mobile phone would normally aim at saving a single mobile phone number in the phonebook. However, the instruction could instead convey two mobile phone numbers simultaneously, prompting the method to save the two contacts. But rather than save the two contacts separately, the method will accommodate both contacts under a single identity. Let’s explore another example using computation operators for calculations shown below.

public class Census{

int multiply(int a, int b){

return a*b;

}

int multiply(int d, int e, int f){

return d*e*f;

}

}
