Java Loops (for, while, do-while)

Java provides different types of loops to perform repetitive tasks.

For Loop

public class ForLoopExample {
    public static void main(String[] args) {
        for (int i = 1; i <= 5; i++) {
            System.out.println("Iteration: " + i);
        }
    }
}

This program uses a for loop to print the iteration number from 1 to 5.

While Loop

public class WhileLoopExample {
    public static void main(String[] args) {
        int i = 1;
        while (i <= 5) {
            System.out.println("Iteration: " + i);
            i++;
        }
    }
}

This example demonstrates the use of a while loop to perform the same task as the for loop above.

Do-While Loop

public class DoWhileLoopExample {
    public static void main(String[] args) {
        int i = 1;
        do {
            System.out.println("Iteration: " + i);
            i++;
        } while (i <= 5);
    }
}

The do-while loop guarantees at least one iteration even if the condition is false at the start.
