Method overloading:
More than one method have same name but different type
of argument or differnt no. of arguments available in same
class or it subclass is called overloading.

Return type of method and access specifier of method is
not a problem in method overloading.

class A{
void diaplay(int a,int b){ }
void display(float a,float b){ }
void display(float a, int b){ }
void display(int a,int b){
void display(){ }

}
