 用Java几行代码实现彩色圣诞树

import java.util.Scanner;
public class TestChristmas {
    public static void main(String[] args) {
        System.out.print("u001b[4;31;42m***********************n");
        Scanner ac = new Scanner(System.in);
        int nub= ac.nextInt();//控制树大小
        int rootLevel = 2;
        int spaceNum = nub - 1;
        for (int i = 1; i <= nub; i++) {            //叶
            spaceNum--;
            for (int g = 0; g <= spaceNum; g++) {
                System.out.print(" ");
            }
            for (int j = 1; j <= ((i * 2) -1); j++) {
                System.out.print("u001b[4;31;42m*");
            }
            System.out.print("n");
        }         //画根部门
        for (int i = 1; i <= rootLevel; i++) {
            for (int g = 1; g < nub; g++) {
                System.out.print(" ");
            }
            System.out.print("**n");

        }
        System.out.print("u001b[4;31;42m***********************n");
    }
}
