Use the modulo operator to implement loops

Loop.java

/*
* use modulo operator to implement loops
*/ 
public class Loop {
    // index
    private static int index;

    // a objects array
    private static obj[] mObjs = new obj[]{
    new obj(0),
    new obj(1),
    new obj(2),
    new obj(3),
    new obj(4),
    };

    // call this method
    private static void fun() {
    index = index % mObjs.length();
    // do something here
    do();   
    }

    public static void main(String[] agrs) {
        while(1) {
            fun();
        }
    }
}

a % b = a IF a < b. So we can implement a loop by calling the method.
