while是最基本的循环,它的结构为: while(布尔表达式){//循环内容} 只要布尔表达式为 true,循环就会一直执行下去。 实例 Test.java 文件代码: publicclassTest{publicstaticvoidmain(String[]args){intx=10;while(x<20){System.out.print("value of x :"+x);x++;System.out.print("\n");}}} 以上实例编...
首先,我们假设需要编写一个程序,用于计算1到n之间所有整数的和。下面是使用do-while循环实现的示例代码: importjava.util.Scanner;publicclassDoWhileExample{publicstaticvoidmain(String[]args){Scannerscanner=newScanner(System.in);System.out.print("请输入一个正整数:");intn=scanner.nextInt();intsum=0;inti...
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"); // l...
In both While and Do-While loops, it is important to note that the condition being tested must eventually return ‘False’ for the loop to close. Otherwise, you’ll end up with an infinite loop, and probably cause a system crash. The Do-While Loop in Java The syntax of the Do-While ...

更新:2007 年 11 月 Loop 陳述式含有 While 或 Until 子句,且對應的 Do 陳述式也含有類似的子句。迴圈的 Do 或 Loop 陳述式中,只有其中一個可以指定條件。 錯誤ID:BC30238 若要更正這個錯誤 移除Do 陳述式或 Loop 陳述式中的 While 或 Until 子句。 請參閱 參考 Do...Loop 陳述式 (Visual Basi...
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.
