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.
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...
HI all , is there a problem with the proposed solution for the Do..while loop in the java course ? it seems working but it wont compile on the simulator . how can i complete the course ? import java.util.Scanner; public class Program { public static void main(String[] args) { Scann...

2. While Loop Example Let us understand thewhileloop with a few examples. 2.1. Print all numbers from 1 to N To print all integers between 1 and 5 using awhile-loop, we can create a condition on a local variablecounterthat must not be less than or equal to 5. ...
来源:https://beginnersbook.com/2015/03/while-loop-in-java-with-examples/ 在上一个教程中,我们讨论了for循环的用法。在本教程中,我们将讨论while循环的用法。如前一个教程中所讨论的,循环用于重复执行同一组语句,直到某个特定条件满足后,程序就跳出这个循环。
Loops are the way to do this. A while loop has a boolean test and a body containing statements, like this: int count = 0; while (count < 100) { // test: boolean test within (..) System.out.println("count:" + count); // body: statements within {..} count = count + 1;...
In this tutorial, we will learn how to use while and do while loop in Java with the help of examples.
it terminates the current loop of any type (for,while,do-while); it terminates a case in theswitchstatement; 1. Syntax The syntax is pretty much simple. Use thebreakkeyword with a semicolon (;). We can additionally use alabelas well. ...
The Java programming language also provides a do-while statement, which can be expressed as follows: do { statement(s) } while (expression); The difference between do-while and while is that do-while evaluates its expression at the bottom of the loop instead of the top. Therefore, the ...
