java实现简单圣诞树的示例代码(圣诞节快乐）

@Test
  public void shengdanshu(){
    //叶子层
    int level = 10;
    //根层
    int rootLevel = 2;
    int spaceNum = level - 1;

    //画叶子
    // 为什么从1开始  不管了就是任性
    for (int i = 1; i <= level; i++) {
      spaceNum--;
      for (int g = 0; g <= spaceNum; g++) {
        System.out.print(" ");
      }
      for (int j = 1; j <= ((i * 2) -1); j++) {
        System.out.print("*");
      }

      System.out.print("
");
    }
 System.out.println("  &＃10084;圣诞节快乐&＃10084;");
    //画根
    for (int i = 1; i <= rootLevel; i++) {
      for (int g = 1; g
