怎么用JAVA编出一个大宝剑

public class Test {
    public static void main(String[] args) {
        String[] strs = new String[] { "   *", "  ***", "  ***", "  ***", "  ***", "  ***", "  ***", "  ***", "  ***",
                "  ***", "  ***", "  ***", "  ***", "  ***", "  ***", "*******", "  ***", "  ***", "  ***", " *****" };
        for (String s : strs) {
            System.out.println(s);
        }
        System.out.println();
    }
}
