In this tutorial, we’ll cover the four types of loops in Java: the for loop, enhanced for loop (for-each), while loop and do-while loop. We’ll also cover loop control flow concepts with nested loops, labeled loops, break statement, continue statement, return statement and local ...
For example, if you want to show a message 100 times, then you can use a loop. It's just a simple example; you can achieve much more with loops. In the previous tutorial, you learned about Java for loop. Here, you are going to learn about while and do...while loops. Java while...

Java do-while loop executes the statements in do block, and then evaluates a condition in the while block to check whether to repeat the execution.
public class JavaDoWhileLoop { public static void main(String[] args) { int i = 5; do { System.out.println(i); i++; } while (i <= 10); } } package com.journaldev.javadowhileloop; public class DoWhileTrueJava { public static void main(String[] args) throws InterruptedException { ...
The Java programming language also provides a do-while statement, which can be expressed as follows: do { statement(s) } while (expression); The difference between do-while and while is that do-while evaluates its expression at the bottom of the loop instead of the top. Therefore, the ...
Do While loop Example 1 int count = 0; do{ System.out.print(count); count++; }while(count < 5);//while this condn is true, loop is executed. //output is 01234 Do While loop Example 2 count = 5; do{ System.out.print(count); count++; }while(count < 5); //output is 5 Fo...
do {} while (i < max)is similar like before, only difference is that the loop body will be execute at least once. while(true) { if (i < max) {break;}}Whenever seebreak; will jump out from thewhileloop. max = 5; i = 0; ...
do { System.out.println(count); } while (count != 0); } First the block is executed and then the truth expression is evaluated. In our case, the condition is not met and thedo whilestatement terminates. The for statement When the number of cycles is know before the loop is initiated...
Example int i = 0; while (i < 5) { System.out.println(i); i++; } Try it Yourself » Note: Do not forget to increase the variable used in the condition, otherwise the loop will never end!Exercise? How many times will the following loop execute?int i = 0;while (i < 4) ...
