Real-Life Examples

To illustrate a practical example of the while loop, we’ve developed a straightforward “countdown” program.

Example

int countdown = 3;

while (countdown > 0) {

  System.out.println(countdown);

  countdown--;
}

System.out.println("Happy New Year!!");

To showcase a practical example of combining the while loop with an if-else statement, let’s consider playing a game of Yatzy.

Example

Output “Yatzy!” when the dice number equals 6.

int dice = 1;

while (dice <= 6) {
  if (dice < 6) {
    System.out.println("No Yatzy.");
  } else {
    System.out.println("Yatzy!");
  }
  dice = dice + 1;
}

When the loop iterates through values 1 to 5, it prints “No Yatzy”. However, when it encounters the value 6, it prints “Yatzy!”.
