菱形“*”的编写

package com.yzy.test;

public class Rhombus{
    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        int s = 9;
        for (int i = 0; i < s; i++) {
            for (int j = s - i; j > 0; j--) {
                System.out.print(" ");
            }
            for (int j = 0; j < 2 * i + 1; j++) {
                System.out.print("*");
            }
            System.out.println();
        }
        for (int i = s; i >= 0; i--) {
            for (int j = 0; j < s - i; j++) {
                System.out.print(" ");
            }
            for (int j = 0; j < 2 * i + 1; j++) {
                System.out.print("*");
            }
            System.out.println();
        }
    }

}
