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 incre
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 ...
Java do-while loop example Here is a simple java do-while loop example to print numbers from 5 to 10. package com.journaldev.javadowhileloop; public class JavaDoWhileLoop { public static void main(String[] args) { int i = 5; do { System.out.println(i); i++; } while (i <= 10)...
Example A basic example of the Java while loop. Other supporting code was removed to improve readability and keep the code short. 1 2 3 4 5 6 intx =0; while(x <5) { System.out.println(x); x = x +1; } 0 1 2 3 4 As shown above, the while loop printed out all the number...
Java:使用while-loop更改行的顺序 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。
Java是一种常用的编程语言,它被广泛应用于各种软件开发领域。下面是关于使用多个条件语句、while循环、for循环和if语句的问题的答案: 1. 多个条件语句:多个条件语句是指在程序中需要根据不...
For example, if you want to show a message 100 times, then you can use a loop. It's just a simple example; you can achieve much more with loops. In the previous tutorial, you learned about Java for loop. Here, you are going to learn about while and do...while loops. Java while...
Test.java 文件代码: publicclassTest{publicstaticvoidmain(String[]args){intx=10;do{System.out.print("value of x :"+x);x++;System.out.print("\n");}while(x<20);}} 以上实例编译运行结果如下: value of x:10value of x:11value of x:12value of x:13value of x:14value of x:15value...
