In this tutorial, we will write a program to count the number backward in java. The program uses a scanner class to take the input from the user and with a do-while loop, it counts backward and displays the result.
If you do not know the working process of do-while loop then click the link below.
Java Program to Count Backward of a Number
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | //count backward of a number using do-while loop in java import java.util.Scanner; public class CountBackNumber { public static void main(String args[]) { int n = 5; Scanner scanner = new Scanner(System.in); System.out.println("Enter the number from where you want to back count: "); n = scanner.nextInt(); do { System.out.print(n + " "); n--; // Decrementing N by 1 in each iteration } while (n >= 0); } } |
Output:
Enter the number from where you want to back count:
10
10 9 8 7 6 5 4 3 2 1 0
