Nov 22, 2024 · Java do-while loop is an Exit control loop. Unlike for or while loop, a do-while check for the condition after executing the statements of the loop body. Example: Suppose you are implementing a game where you show some options to the user, press 1 to do this .., press 2 to do this .. etc and press ‘Q’ to quit the game.

Jan 2, 2023 · The Java do-while loop executes a block of statements in do block, and evaluates a boolean condition in while block to check whether to repeat the execution of block statements again or not, repeatedly.

Learn how to use the 'do while' loop in Java with examples and syntax explanations. Perfect for beginners and seasoned programmers.

Feb 16, 2025 · The do-while loop works just like the while loop except for the fact that the first condition evaluation happens after the first iteration of the loop: do { statement; } while (Boolean-expression); Let’s have a look at a simple example: int i = 0; do { System.out.println("Do-While loop: i = " + i++); } while (i < 5); 3. Conclusion

The do-while loop in Java is a control flow statement that allows code to be executed repeatedly based on a given boolean condition. Unlike the while loop, the do-while loop guarantees that the code block is executed at least once before the condition is tested.

Feb 18, 2024 · The do-while loop in Java provides a powerful tool for executing a block of code repeatedly with the guarantee of at least one execution. Understanding its syntax and behavior, along with careful consideration of initialization, condition checks, and modifications within the loop, can help in effectively utilizing this control flow statement.

The do-while loop executes a block of code while a boolean expression evaluates to true. It checks the boolean expression after each iteration. It terminates as soon as the expression evaluates to false.

Sep 11, 2022 · In this tutorial we will discuss do-while loop in java. do-while loop is similar to while loop, however there is a difference between them: In while loop, condition is evaluated before the execution of loop’s body but in do-while loop condition is …

The syntax of the Java do-while loop is: The test_expression must be evaluated using a boolean value, either true or false. It controls when the loop terminates. Test Expression – Evaluate a condition that controls the termination of the loop. Example: i <= 10. Update Expression – Used to increment or decrement the loop variable. Example: i++. 1.
