Java do while 循环 与while 循环相似,do/while 循环在每次迭代结束时测试条件,而不是在开始时测试条件。有了这个循环,循环中的代码至少运行一次,因为没有进入的入口,只有退出的出口: package com.opensource.example; public class Example { public static void main(String[] args) { int count = 9; do {...
inti=-10;//Simple while loopwhile(i>0){System.out.println(i);//Does not print anythingi++;}//Do-while loopdo{System.out.println(i);//Prints -10 and then exitsi++;}while(i>0); Other than this there is no difference between both loops. Happy Learning !!

} while (be); 注意:do-while语句须要一个分号。 2. for语句 最经常使用的循环语句是for语句。 它将与循环相关的3个表达式——初始化表达式、循环測试表达式和计数表达式集中在for后面一个()中。这样的3表达式的for循环(Three-expression for loops)自C语言起,差点儿在全部语言中被採用。
本资料包系统性地探讨了Java编程语言中程序流程控制的核心机制,重点解析了条件判断语句(if-else、switch)和循环结构(while、do-while、for)的语法、特性及应用。通过对不同控制结构在解决实际问题(如实现猜数字游戏、打印九九乘法表、数据...
