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 ...
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...
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"); ...
Java是一种常用的编程语言,它被广泛应用于各种软件开发领域。下面是关于使用多个条件语句、while循环、for循环和if语句的问题的答案: 1. 多个条件语句:多个条件语句是指在程序中需要根据不...
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...
In Python, we use awhileloop to repeat a block of code until a certain condition is met. For example, number = 1 while number <= 3: print(number) number = number + 1 Output 1 2 3 In the above example, we have used awhileloop to print the numbers from1to3. The loop runs as...
循环语句是编程中非常常见的语句之一,它可以让程序重复执行一段代码,直到满足某个条件后停止循环。本文将介绍Java中的四种循环语句:while、do-while、for、foreach,以及它们的应用场景和优缺点。 摘要 本文将对Java中的四种循环语句进行详细介绍,并分别从源代码解析、应用场景案例、优缺点分析、类代码方...
Test.java 文件代码: publicclassTest{publicstaticvoidmain(String[]args){intx=10;do{System.out.print("value of x :"+x);x++;System.out.print("\n");}while(x<20);}} 以上实例编译运行结果如下: value of x:10value of x:11value of x:12value of x:13value of x:14value of x:15value...
