Question

Write a Java program to input three integer numbers and find out the
greatest and smallest number.

Answer 1

Answer:

import java.util.Scanner;

public class Exercise3 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.print("Input the 1st number: ");

int num1 = in.nextInt();

System.out.print("Input the 2nd number: ");

int num2 = in.nextInt();

System.out.print("Input the 3rd number: ");

int num3 = in.nextInt();

if (num1 > num2)

if (num1 > num3)

System.out.println("The greatest: " + num1);

if (num2 > num1)

if (num2 > num3)

System.out.println("The greatest: " + num2);

if (num3 > num1)

if (num3 > num2)

System.out.println("The greatest: " + num3);

}

}

Answer 2

Answer:

import java.util.*;

public class Question {

 public static void main(String[] agrs) {

    Scanner sc = new Scanner(System.in);

    int a = sc.nextInt();

    int b = sc.nextInt();

    int c = sc.nextInt();

    int g = Math.max(a,Math.max(b,c));

    int s = Math.min(a,Math.min(b,c));

   System.out.printn("Greatest Number = "+g);

   System.out.printn("Smallest Number = "+s);

}
