java实现输出一个菱形图形

public class V {
    public static void main(String[] args) {
        for(int i=1;i<=8;i++){
            System.out.print(" ");
        }
        System.out.println("*");
        for(int i=2;i<=9;i++){
            for(int k=1;k<=9-i;k++){
                System.out.print(" ");
            }
            System.out.print("*");
            for(int j=1;j<=2*i-3;j++){
                System.out.print(" ");
            }
            System.out.println("*");
        }
        for(int i=1;i<=7;i++){
            for(int k=1;k<=i;k++){
                System.out.print(" ");
            }
            System.out.print("*");
            for(int j=1;j<=15-2*i;j++){
                System.out.print(" ");
            }
            System.out.println("*");
        }
        for(int i=1;i<=8;i++){
            System.out.print(" ");
        }
        System.out.println("*");
    }
}
