Return more than one value from a function in Java

Question

How to return more than one value from a function in Java? Can anyone give sample code for doing this using tuples? I am not able to understand the concept of tuples.

Is this what you are looking for?

public class Tuple {
    public static void main(String[] args) {
        System.out.println(f().a);
        System.out.println(f().b);
    }

    static Pair f() {
        Tuple t = new Tuple();
        return t.new Pair("hi", 3);

    }

    public class Pair {
        public final String a;
        public final Integer b;

        public Pair(String a, Integer b) {
            this.a = a;
            this.b = b;
        }
    }
}
