FLAG In Java

• In Java programming, the term "flag" typically refers to a variable used as a signal or indicator within a program's flow. It's a common programming concept, not specific to Java, but widely applied in various contexts within Java development. Boolean Flags:
• 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.");
    }
