Do-while loop: Countdown

In this problem, you will create a program that reads an integer n from standard input, uses a do-while loop to count down from n to 1 printing each number, and displays "Done!" at the end.

Learning Objective: Understand that do-while executes at least once

Overview

The do-while loop checks condition after execution, so the loop body always runs at least once. Let's create a countdown from the input value!

Specifications

• Read integer n using Scanner
• Use do-while for countdown
• Display current number each iteration
• Repeat while count is greater than 0
• Display "Done!" at the end

Input Format

n

• n: Starting value for countdown (integer >= 1)

Output Format (when n=3)

3
2
1
Done!
