Question

java program where ask the user to enter three integers. display the numbers in reverse order. for example: 1 2 3 would display as 3 2 1.

Answer 1

In Java, a program can be written to prompt the user to enter three integers and display them in reverse order using Scanner for input and System.out.printf for output.

Step-by-step explanation:

A Java program to ask the user to enter three integers and display the numbers in reverse order can be implemented using simple input and output operations. The program will use a Scanner object to read the integers entered by the user, store them in variables, and then print them out in the reverse order of entry. Here's a simplified version of the program:

import java.util.Scanner;

public class ReverseIntegers {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("Enter three integers:");
int first = scanner.nextInt();
int second = scanner.nextInt();
int third = scanner.nextInt();
scanner.close();

System.out.printf("You entered: %d %d %d\\", first, second, third);
System.out.printf("In reverse order: %d %d %d", third, second, first);
}
}

This program will prompt the user to enter three integers, read those integers using a Scanner object, and then output the numbers in reverse order.
