In the next example,indexstart with 0 and check if it is less than the array length. As we are not incrementing its value, it will always be less than 5, no matter how many iterations happen. This loop is an infinite loop. Integer[]array=newInteger[]{1,2,3,4,5};intindex=0;wh...
The while loop loops through a block of code as long as a specified condition is true:SyntaxGet your own Java Server while (condition) { // code block to be executed } In the example below, the code in the loop will run, over and over again, as long as a variable (i) is less ...
You need to use loops. You will learn about two loopswhileanddo..whilein this article with the help of examples. If you are familiar withwhile and do...while loops in Java, you are already familiar with these loops in Kotlin as well. Kotlin while Loop The syntax ofwhileloop is: while...
Using theandoperator&&we can connect two conditions together. Chaining two conditions together with&&ensures the loop only runs when both conditions are true, and will terminate if any of them becomes false. public class example { public static void main(String[] args) { int x = 0; int y ...
Java For and While LoopsThis handout introduces the basic structure and use of Java for and while loops with example code an exercises. See also the associated CodingBat java loop practice problems using strings and arrays. Written by Nick Parlante. ...

Thewhileloop loops through a block of code as long as a specified condition is true. Syntax while(condition) { // code block to be executed } Example In the following example, the code in the loop will run, over and over again, as long as a variable (i) is less than 10: ...

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...
while(i < max){} will keep executing ifi < maxis true, otherwise will jump out from thewhileloop. Possible execute 0 times. max = 5; i = 0; while(i < 5){ System.out.printf("%d ", i); i++;} // the result will be like this ...
