29 - Do-While Loop in Java (Hindi/Urdu)

LIKE, SHARE & SUBSCRIBE

The do while statement is a type of iterative statements which are used to execute Java statements in a repetitive fashion.

Now, this repetition depends on the output of the conditional expression. If the output of conditional statement is true, then the execution of Java statements occurs. And when the output of conditional statement is false then the execution process stops.

You can see here that while and do-while statement's working is almost same. But there is a basic difference between them.

If the initial output of while statement's conditional expression is false, then the execution process of Java statements in while loop never occurs.

But in case of do while statement the Java statements get executed a single time, even if the initial output of conditional statement in the do-while statement is false. So the advantage of do-while statement is that it executes Java statements which are contained in the body of the do-while statement and this is very useful for the validation and termination of Java code.

And in maximum cases, the do-while statement is used at the end of Java program.
