Compare Three Numbers (Equal, Different)

Write a Java program that accepts three numbers and prints "All numbers are equal" if all three numbers are equal, "All numbers are different" if all three numbers are different and "Neither all are equal or different" otherwise.

Test Data
Input first number: 2564
Input second number: 3526
Input third number: 2456

Sample Solution:

Java Code:

import java.util.Scanner;
public class Exercise30 {

  public static void main(String[] args)
    {
        Scanner in = new Scanner(System.in);

        System.out.print("Input first number: ");
        int x = in.nextInt();
        System.out.print("Input second number: ");
        int y = in.nextInt();
        System.out.print("Input third number: ");
        int z = in.nextInt();

        if (x == y && x == z)
        {
            System.out.println("All numbers are equal");
        }
        else if ((x == y) || (x == z) || (z == y))
        {
            System.out.println("Neither all are equal or different");
        }
        else
        {
            System.out.println("All numbers are different");
        }
    }
}

Sample Output:

Input first number: 2564                                                                                      
Input second number: 3526                                                                                     
Input third number: 2456                                                                                      
All numbers are different
