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...

在Java5 中引入了一种主要用于数组的增强型 for 循环。 while 循环 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("val...
In this tutorial, we will learn how to use while and do while loop in Java with the help of examples.
