To demonstrate a practical example of the for loop, let's create a program that counts to 100 by tens:ExampleGet your own Java Server for (int i = 0; i <= 100; i += 10) { System.out.println(i); } Try it Yourself » In this example, we create a program that only print ...
Example 1: BasicforLoop publicclassForLoopExample{publicstaticvoidmain(String[]args){for(int i=0;i<5;i++){System.out.println("Iteration: "+i);}}} In this example, the loop initializesito 0, checks ifiis less than 5, and prints the iteration number. After each iteration,iis incremented...
As mentioned in syntax, theinitialization, termination, and increment are optional parts, that can be controlled from other places. Or the for loop might not have all of them. For example, we can rewrite the previous example as below. We have taken out thecounterinitialization before the loop...
Foreach循环(Foreach loop)是计算机编程语言中的一种控制流程语句,通常用来循环遍历数组或集合中的元素。foreach语法格式如下: for( 元素类型T 元素变量t : 遍历对象obj){ 引用了t 的java 语句; } 1. 2. 3. 以下实例演示了普通for循环和foreach循环使用: private static void test() { List<String> names...
下面,我将给出一个详细的示例,使用数组作为数据源,通过for循环倒序输出数组中的元素。这个示例不仅可以直接运行,而且具有一定的参考价值,因为它展示了如何在Java中进行基本的循环遍历和数组操作。 1.1示例代码 publicclassReverseForLoopExample{publicstaticvoidmain(String[] args){// 定义一个整型数组,这里以简单的1...
see something that we did not explain: the expressionbreak;. That expression is used to jump out of the loop, which means that it takes the command right after the loop, without executing the rest of it, but instead doing whatever code is next. Here’s an example of how you can use ...
classForLoopExample2 { publicstaticvoidmain(String args[]){ for(inti=1; i>=1; i++){ System.out.println("The value of i is: "+i); } } } 这是一个死循环,我们初始化里给变量i赋值为1,循环条件是i>=1,因为i的值是1,后面的递增运算i++只能让变量i的值越来越大,所以这个循环条件i>=1...
以下是一个简单的 Java 程序，使用 for 循环输出数字 0 到 9：public class ForLoopExample { public...
java public class ForLoopExample { public static void main(String[] args) { for (int i = 0; i < 5; i++) { System.out.println("Count is: " + i); } } } 解释 int i = 0:初始化循环计数器 i 为 0。 i < 5:循环条件,只要 i 小于 5,循环就会继续。
java public class DoWhileLoopExample { public static void main(String[] args) { int count = 0; do { System.out.println("Count is: " + count); count++; } while (count < 5); } } 4. 增强 for 循环(用于遍历数组或集合) 增强for 循环(也称为 for-each 循环)用于遍历数组或集合中的元素...
