• The most common type of flag is a boolean variable. It holds a true or false value, indicating whether a specific condition has been met or a particular state exists.
  Sample program :
  

boolean foundEven = false;

    for (int num : numbers) {

        if (num % 2 == 0) {

            foundEven = true; // Set the flag

            break;

        }

    }

    if (foundEven) {

        System.out.println("An even number was found.");

    }
