java中Enum类中的常用方法，实现接口

public class SeasonTest {
    public static void main(String[] args) {
        Season spring = Season1.SPRING;
        // toString()
        System.out.println(spring);
        
        System.out.println("************");
        // values()
        Season[] values = Season.values();
        for (int i = 0; i < values.length; i++) {
            System.out.println(values[i]);
        }
        
        System.out.println("************");
        // valueOf(String objName)
        Season winter = Season.valueOf("WINTER");
        System.out.println(winter);
        winter.show();
    }
}
interface Info {
    void show();
}

//使用enum关键字定义枚举类并实现接口
enum Season implements Info{
    // 1.提供当前枚举类的对象，多个对象之间用","隔开，末尾对象";"结束
    SPRING("春天", "春暖花开"){
        @Override
        public void show() {
            System.out.println("春天在哪里");
        }
    },
    SUMMER("夏天", "夏日炎炎"){
        @Override
        public void show() {
            System.out.println("宁夏");
        }
    },
    AUTUMN("秋天", "秋高气爽"){
        @Override
        public void show() {
            System.out.println("秋天回不来");
        }
    },
    WINTER("冬天", "冰天雪地"){
        @Override
        public void show() {
            System.out.println("大约在冬季");
        }
    };
    
    // 1.声明Season对象的属性：private final修饰
    private final String seasonName;
    private final String seasonDesc;
    
    // 2.私有化类的构造器，并给对象属性赋值
    private Season(String seasonName, String seasonDesc) {
        this.seasonName = seasonName;
        this.seasonDesc = seasonDesc;
    }
    
    // 4.其他诉求1：获取枚举类的对象的属性
    public String getSeasonName() {
        return seasonName;
    }
    public String getSeasonDesc() {
        return seasonDesc;
    }
    
    // 4.其他诉求2：提供toString()
    @Override
    public String toString() {
        return "Season [seasonName=" + seasonName + ", seasonDesc=" + seasonDesc + "]";
    }
}
