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...
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 ...

在Java中,可以使用continue关键字来跳出本次循环,并进入下一次循环。 以下是实现Java跳出while本次循环进入下一次循环的代码示例: publicclassWhileLoopExample{publicstaticvoidmain(String[]args){inti=0;while(i<5){i++;if(i==3){continue;// 跳出本次循环,进入下一次循环}System.out.println("当前数字:"+...
publicclassJumpOutWhileLoopExample{publicstaticvoidmain(String[]args){// 1. 使用break语句intcount=0;while(true){count++;if(count==5){break;}System.out.println("count: "+count);}System.out.println("Loop ended.");// 2. 使用return语句int[]array={1,2,3,4,5};inttarget=3;intindex=find...
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...
while 语句是 Java 循环结构中的一类,本文将对 Java 中的 while 循环语句进行讲解。 一、什么是 while 循环语句 在Java 中,while 循环是一种用于重复执行特定代码块的循环语句。 它会在循环开始前检查一个条件表达式的真假,并只有当条件为真时才执行循环体内的代码。 当循环体内的代码执行完毕后,再次检查条件表达...
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"); ...
classWhileLoopExample2 { publicstaticvoidmain(String args[]){ inti=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)永远返回的值都...
