12. Method Overloading

package lesson93;

public class MethodOverloading {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		System.out.println(Add(1,2));
		System.out.println(Add(1.8,2.2));
		System.out.println(Add("Hello","Java"));
	}
	
	public static int Add(int a, int b) {
		return (a+b);
	}
	
	public static double Add(double a, double b) {
		return (a+b);
	}
	
	public static String Add(String a, String b) {
		return (a+b);
	}
}

public class DataArtist {
    ...
    public void draw(String s) {
        ...
    }
    public void draw(int i) {
        ...
    }
    public void draw(double f) {
        ...
    }
    public void draw(int i, double f) {
        ...
    }
}

This is called overloading method, and Java can distinguish between methods with different method signatures.
