Using the do-while Loop in Java: Basics and Examples

  • Hello dear Jetto Net Members,

    In this article, we will discuss the "do-while" loop in the Java programming language. The do-while loop allows you to perform a specific operation at least once and then checks the condition. In this way, the do-while loop differs from the while loop.

    The general structure of the do-while loop is as follows:

    Code
    do {
        // actions to be taken
    } while (condition);

    The operations to be performed are performed at least once before the condition of the loop is checked. The condition is then checked and the loop is repeated as long as the condition is true.

    For example, a do-while loop that asks the user to enter a number and repeats the operation as long as the number is negative might look like this:

    This loop repeats the operation until the user enters a positive number.

    The do-while loop is useful when you need to perform a certain operation at least once and provides a different use than the while loop.

    I hope this simple example helps you understand the basics of the do-while loop in Java. If you have any questions, feel free to ask.

    Happy coding!
