Question

Write a Java program to determine the larger of 2 numbers and the largest of 3 numbers. Each section must use its own method. Method overloading must be used for this exercise.

Method for 2 numbers public static double max(double p, double q) Method for 3 numbers public static double max(double p, double q, double r)

Answer 1

public class Max {

    // 1
    public static double max(double p, double q) {
        if (p > q) {
            return p;
        } else {
            return q;
        }
    }

    // 2
    public static double max(double p, double q, double r) {
        return max(p, max(q, r));
    }

    public static void main(String[] args) {
        System.out.println(max(4, 9));
        System.out.println(max(7, 3));
        System.out.println(max(2, 7, 9));
        System.out.println(max(9, 2, 7));
        System.out.println(max(6, 7, 2));
    }
}
