1、本篇博客主要介绍几道for循环嵌套练习题目

2、源码如下

class ForForTest 
{
    public static void main(String[] args) 
    {
        /*
        *****
        ****
        ***
        **
        *
        */
        /*
        int z = 5;
        for (int x = 1; x<=5 ;x++ )//1-5 1-4 1-3//1-5 2-5 3-5
        {
            for (int y=1; y<=z ; y++ )
            {
                System.out.print("*");
            }
            System.out.println();
            z--;
        }
        */

        {
            for (int y=z; y<=5 ; y++ )
            {
                System.out.print("$");
            }
            System.out.println();
            z++;
