        int x, y;
        x = 10;
        y = 20;
        if (x < y) {
            System.out.println("x is less than y");
        x = x * 2;
        if (x == y) {
            System.out.println("x now equal to y");
        x = x * 2;
        if (x > y) {
            System.out.println("x now greater than y");
        // this won't display anything
        if (x == y)
            System.out.println("you won't see this");
x is less than y
x now equal to y
x now greater than y
