Java Programming for Complete Beginners - Java 16 - Step 07 - Do While Loop in Java - an Introduction

The video tutorial explains the do while loop, its syntax, and how it differs from the while loop. It highlights that the do while loop executes the code block at least once, even if the condition is false, unlike the while loop which checks the condition first. The tutorial provides examples to illustrate these differences and offers guidance on when to use each loop type.

What is the primary structural difference between a while loop and a do while loop?

• A while loop executes at least once regardless of the condition.

• A do while loop does not require a condition.

• The condition check is at the end in a do while loop.

• The condition check is at the start in a do while loop.

In a do while loop, when is the condition checked?

• Before the loop starts

• After the loop executes once

• Only if the loop executes twice

• It is never checked

What happens if the condition in a while loop is false initially?

• The loop executes twice

• The loop executes once

• The loop executes indefinitely

• The loop does not execute at all

Why might you choose a do while loop over a while loop?

• To make the code more complex

• To execute the loop only if the condition is false

• To avoid using a condition

• To ensure the loop executes at least once

Which loop guarantees that the code block will run at least once?

• While loop

• Infinite loop

• Do while loop

• For loop
