If the number of iteration is not fixed, it is recommended to use while loop.. Syntax: The difference lies in the fact that if the condition is true at the starting of the loop the statements would still be executed, however in case of while loop it would not be executed at all. How to Use a While Loop to Iterate an Array in Java: Today I will be showing you how to use Java to create a While loop that can be used to iterate through a list of numbers or words.

When the condition returns false, the control comes out of a loop and jumps to the next statement after a while loop. While all the ways provide similar basic functionality, they differ in their syntax and condition checking time. Java do while loop executes the statement first and then checks for the condition.Other than that it is similar to the while loop. At the very start of the while loop, the computer checks a condition having to do with the user’s input. If you run the above example, the loop will execute for infinite and print the number repeatedly with an increment of the value.. Java Do While Loop. The statement is given in the do while loop, the statement execute for one time after that it only gets executed when the condition is true.

To make a Java While Loop run indefinitely, the while condition has to be true forever. Java While Loop. While loop; Infinitive while loop; Apart from the above-mentioned sub-topics, we will also discuss a brief comparison between Java for-loop and while loop through the programs so that you can accomplish the same task using two different, yet common iteration statements. while loop: A while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The topics included in this article are mentioned below: We will cover the below topics as a part of this tutorial. In the last tutorial, we discussed for loop. Then when the computer is inside the loop, the computer asks for more input to feed the loop’s next iteration. Java for and while loops questions for practice Categories Problems , Java In this section we will cover some questions which are asked on Java for and while loops. Active 5 days ago. Closed.
