Java Do While Loop

When we wish to test the exit condition at the end of the loop, we use a do-while loop. The do-while loop always executes its body at least once, because its conditional expression is at the bottom of the loop.

Example:

public class Myclass {
public static void main(String[] args) {
int num = 9;
boolean divisibleBy7 = false;
do {
System.out.println(num);
if (num % 7 == 0)
divisibleBy7 = true;
num--;
} while (divisibleBy7 == false);
}
}

Output

9
8
7
