In Java A method is a block of code which only runs when it is called. You can pass data, known as parameters, into a method.

public class tut5 {
    static int sum(int x, int y){
        int c = x+y;
        return c;
    }
    // method overloading...
    static int sum(int x, int y, int z){
        return x+y+z;
    }
    static float sum(float a, float b){
        return a+b;
    }
    public static void main(String[] args) {
        System.out.println(sum(2, 4)); // int
        System.out.println(sum(2, 3, 4)); // int
        System.out.println(sum(23.07f, 30.06f)); // float
    }
}
