It is simple. 

Overloading is required, if you want a particular method to change its behavior based on the parameters passed.

Suppose you have a sum function

Sum(int i, int j)

This will add two integers, now if the requirement is that it should add 2 floats as well...then you need to overload it..

Sum(float i, float j)

In Java one of the main concept is polymorphism
poly means many..taking many form with existing one.
if we use a method callled add();

add(int x,int y) we can  add 2 integers

add(float x,float y)we can add 2 float numbers

add(double x,double y) we can add 2 double numbers

with one add() method we are doing multiple works.so here polymorphism comes into picture.
