The **do…while** loop is nearly identical to the `while` loop, but instead of checking the *conditional* statement before the loop starts, the **do…while** loop checks the conditional statement **after** the first run, then continues onto another iteration.

**Syntax:**


As you can see, this will run the loop **at least** once before checking the conditional.

**Following is an example of do…while loop in Java:**


class HelloWorld{
  public static void main(String[] args){
    int number=5;
    do{
      System.out.println("Value of number is: "+ number);
      number++;
    } while(number<=9); // the condition is being checked after the first run
  }
}

## Why use do-while?
$$$$
A *do-while* loop is used where your loop should execute **at least one** time. For example, let's say you want to take an *integer* input from the user until the user has entered a **positive** number. In this case, we will use a **do-while** as we have to run the loop **at-least once**. The loop takes an initial input, and it will continue running until the user enters a **positive** number.
