Example 3: Using while Loop for Input Validation import java.util.Scanner; public class InputValidationExample { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int number; System.out.println("Enter a number between 1 and 10:"); number = scanner.nextInt...
Programmers makes mistake. If theconditional-expressiongiven in while loop never terminatesthen the loop will result in an infinitewhile-loop. For example, in the previous program, if theindexvalue is not incremented after each iteration, then the condition will never terminate. In the next example...
Example A basic example of the Java while loop. Other supporting code was removed to improve readability and keep the code short. int x = 0; while (x < 5) { System.out.println(x); x = x + 1; } 0 1 2 3 4 x x Java Essentials - While loop in java Share Watch on Java...
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 ...
class WhileLoopExample2 { public static void main(String args[]){ int i=10; while(i>1) { System.out.println(i); i++; } } } 在while后面的括号里面的循环条件是i>1,因为i的初始值是10(>1),在循环代码里面又不停地给i的值进行递增(i++)操作,i的值会越来越大,这样循环条件(i>1)永远返...

Example while(i <10) { text +="The number is "+ i; i++; } Try it Yourself » If you forget to increase the variable used in the condition, the loop will never end. This will crash your browser. The Do While Loop Thedo whileloop is a variant of the while loop. This loop ...
truein the do while loop. Here is a simple do while java infinite loop example. package com.journaldev.javadowhileloop; public class DoWhileTrueJava { public static void main(String[] args) throws InterruptedException { do { System.out.println("Start Processing inside do while loop"); ...
while loop is terminated. Flowchart of while Loop Example: Kotlin while Loop // Program to print line 5 times fun main(args: Array<String>) { var i = 1 while (i <= 5) { println("Line $i") ++i } } When you run the program, the output will be: Line 1 Line 2 Line 3 Line...
If the test expression in the while and do...while loop never evaluates to false, the body of loop will run forever. Such loops are called infinite loop. For example: Infinite while loop while (true) { // body of while loop } Infinite do...while loop do { // body of while loop...
