Example 3: Using while Loop for Input Validation import java.util.Scanner; public class InputValidationExample { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int number; System.out.println("Enter a number between 1 and 10:"); number = scanner.nextInt...
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 incremented after each iteration, then the condition will never terminate. In the next example...
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 ...
truein the do while loop. Here is a simple do while java infinite loop example. package com.journaldev.javadowhileloop; public class DoWhileTrueJava { public static void main(String[] args) throws InterruptedException { do { System.out.println("Start Processing inside do while loop"); // l...
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...
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...
Hello again... next code I stuck and can’t find out what’s wrong is import java.util.Scanner; public class Main { public static void main(String[] args) {
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...
That was just a simple example; we can achieve much more efficiency and sophistication in our programs by making effective use of loops. There are 3 types of loops in C++. for loop while loop do...while loop In the previous tutorial, we learned about the C++ for loop. Here, we are ...
