for循环嵌套打印星星

 

 

import java.util.Scanner;
public class For02{
    public static void main(String[] args){
    
    //Scanner myScanner = new Scanner(System.in);
    System.out.println("输出星星");
    
    for(int hang=1;hang<=5;hang++){//外层 行
        
        for(int lie=1;lie <=hang;lie++){//内循环 列
            System.out.print("*");//内层 制表符    
                                       }
    System.out.println();//外层结束后打印回车
    
                                   }
    
                                           }
