when run the code bellow :

public class test1 {

public static void main(String[] args) {

String x = "hello";

String y = "World";

String z = "Hello";

System.out.println(x.compareTo(y));

System.out.println(x.compareTo(z));

System.out.println(y.compareTo(x));

}

}

The output is:

17

32

-17

Why the output is numbers?
