In Java, a void function (or method) does not return any value. However, you can use the return statement to exit the method early if needed. The return statement in a void method does not return any value, it simply exits the method.

Do I Return in a Void Function in Java? Examples

Here’s an example:

public class Ex1 {
    public static void main(String[] args) {
        // Define items and their weights
         printMessage(true);
        printMessage(false);
    }

    public static void printMessage(boolean condition) {
        if (condition) {
            System.out.println("Condition is true!");
            return; // Exits the method early if condition is true
        }
        System.out.println("Condition is false!");
    }
}

Output

Condition is true!
Condition is false!
