在Java中,可以使用do-while循环来实现循环控制。do-while循环与while循环的不同之处在于,do-while循环会先执行一次循环体,然后再判断循环条件是否满足。下面是一个使用do-while循环实现循环控制的示例: public class DoWhileLoopExample { public static void main(String[] args) { int count = 0; do { System....
Now let us take an example of the empty while loop. See the example below:// class public class Main { public static void main(String[] args){ // variable defining int num = 0; // while loop java while(++num < 5){ ; } } } ...
2. Java Do-while Example The following program demonstrates the basic usage of a do-while loop. The program prints the numbers from 1 to 5. int i = 1; do { System.out.println(i); i++; } while (i <= 5); The program outputs: 1 2 3 4 5 3. Difference between while Loop and...
首先,我们假设需要编写一个程序,用于计算1到n之间所有整数的和。下面是使用do-while循环实现的示例代码: importjava.util.Scanner;publicclassDoWhileExample{publicstaticvoidmain(String[]args){Scannerscanner=newScanner(System.in);System.out.print("请输入一个正整数:");intn=scanner.nextInt();intsum=0;inti...

publicclassWhileLoopExample{publicstaticvoidmain(String[] args){inti=1;while(i <=5) { System.out.println(i); i++;// 更新条件变量} } } 在这个示例中,我们声明了一个变量i并初始化为1。while循环的条件是i <= 5,这意味着只要i的值小于或等于5,循环就会继续执行。在循环体内,我们打印i的值,并...
Java do while loop 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);...
}while(true); 1. 2. 3. 示例: public class DoWhileExample2 { public static void main(String[] args) { do { System.out.println("infinitive do while loop"); } while (true); } } 1. 2. 3. 4. 5. 6. 7. 执行结果如下 -
Java无限do-while循环 如果在do-while循环中传递参数值为:true,它将是一个无限do-while循环。 语法: do{//code to be executed}while(true); Java 示例: publicclassDoWhileExample2{publicstaticvoidmain(String[] args){do{ System.out.println("infinitive do while loop"); ...
}while(i>1); } } 输出: 9 8 7 6 5 4 3 2 do-while循环示例(遍历数组) 这个例子里,我们有一个整型数组,我们使用do-while遍历和显示数组里面的每个元素。 class DoWhileLoopExample2 { public static void main(String args[]){ int arr[]={2,11,45,9}; ...
