In method overloading method performs the different task at the
different input parameters with same method name and in same class.
To explain the concept of overloading I have
created two classes Poly
public class poly
//these two functions, sum(), are overloaded.
public int sum(int x, int y)
return (x + y);
public virtual int sum(int x, int y, int z)
return (x + y + z);
