Method Overloading

What is method overloading?

If a class has multiple methods with same name but different parameter lists, then it is known as Method Overloading.

Method overloading is achieved by:

Changing number of arguments

void method(int i) {
     //code
}

void method(int i , int j) {
     //code
}

Changing type of arguments

void method(int i) {
     //code
}

void method(double i) {
     //code
}

Method Overloading is not possible by changing the return type of method. On doing so, Compile time error will be raised.

TIP

When you are told to overload a method and some of them have same datatype in their function signature, increase the number of parameters using dummy parameters.
