Do-While Loop

Do-While loop in java is a loop that will execute at least once even when the loop condition is false initially.

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

Count is: 1
Count is: 2
Count is: 3
Count is: 4
Count is: 5

In this example, the count is 1 initially, which satisfies the loop condition count<= 5. This program will execute like it was a normal while loop.

Now we change the initial value for count to 6, makes it no longer satisfy the loop condition.

public class Main {
    public static void main(String[] args) {
        int count = 6;
        
        do {
            System.out.println("Count is: " + count);
            count++;
        } while (count <= 5);
    }
}

Count is: 6

This time, even the loop condition is not satisfied, the loop is executed once.
