Different OOP programming languages were strong typed language such as Java and C++, it means that methods and variables type should be defined (int, float, double, string, etc.) that’s the reason why there is method overloading. Method overloading is having methods in a class that have same method name but different in parameters. It is a form  of Polymorphism.
For example in this code:

class Compute{

public void Add(int param1, int param2) {
//do addition computation here…
}
public void Add(float param1, int param2) {
//do addition computation here…
}
public void Add(int param1, float param2) {
//do addition computation here…
}
}// end class

Now, if we talk about numbers its data type could be a int, double or float. Right? In the code we could then pass those types in method “Add()” to be able to execute addition.

class MyClass{

public static void main (String[] args) {

Compute comp = new Compute;
comp.Add(1,1);
comp.Add(5.5,1);
comp.Add(10000000000000,999999999999999);

}

} // end class

That’s it the “Method Overloading”.
