Chaining two conditions together with && ensures the loop only runs when both conditions are true, and will terminate if any of them becomes false. public class example { public static void main(String[] args) { int x = 0; int y = 0; while (x < 5 && y < 6) { x = x + 1;...

4. Infinite While Loop 5. Exercise 6. Conclusion 1. Introduction In programming, loops are fundamental constructs that allow us to execute a block of code repeatedly under certain conditions. Java provides various loop structures, and one of the simplest among them is the while loop. The while...
Java While 循环 循环 只要达到指定的条件,循环就可以执行代码块。循环很方便,因为它们节省时间,减少错误,并且使代码更具可读性。Java While 循环 只要指定的条件为 true,while 循环就会遍历代码块:语法 while (condition) { // 要执行的代码块 } 在下面的示例中,只要变量(i)小于 5,循环中的代码就会反复运行:...
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 ...
The while loop in Java continually executes a block of statements until a particular condition evaluates to true, else the loop terminates.
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...
Java中使用while循环可以改变行的顺序。while循环是一种迭代结构,它会重复执行一段代码块,直到指定的条件不再满足为止。 在使用while循环改变行的顺序时,可以通过定义一个计数器变量来控制循环的次数。通过递增或递减计数器的值,可以改变行的顺序。 以下是一个示例代码: 代码语言:txt 复制 int count = 1; while ...
i = 4 false The loop is terminated. To learn more about loop conditions, visit JavaScript Comparison and Logical Operators. Example 2: Sum of Only Positive Numbers let num = 0, sum = 0; // loop as long as num is 0 or positive while (num >= 0) { // add all positive numbers sum...
