新．使用二重循环打印如图-1所示的图形。

package cn.bdqn09;import java.util.Scanner;public class S {public static void main(String[] args) {for (int i = 1; i <=4; i++) {for (int j = 0; j <2*i-1; j++) {System.out.print("*");}System.out.print("\n");}for (int i =1;i<=3; i++) {for (int j = 0; j <6-2*i+1; j++) {System.out.print("*");}System.out.print("\n");}}}
