Java基础-枚举enum和switch的用法

package com.hspedu.homework_;

public class Course441 {
    public static void main(String[] args) {

        Color green = Color.GREEN;
        green.show();
        Color red = Color.RED;
        // 枚举enum和switch的用法  switch(xxx)给定一个枚举对象
        switch (red) {
            case RED:
                System.out.println("红色");
                break;
            case BLUE:
                System.out.println("蓝色");
                break;
            case BLACK:
                System.out.println("黑色");
                break;
            case GREEN:
