java自定义枚举类

// 测试
public class SeasonTest {
    public static void main(String[] args) {
        Season spring = Season.SPRING;
        System.out.println(spring);
        System.out.println(spring.getSeasonName());
        System.out.println(spring.getSeasonDesc());
    }
}
// 自定义枚举类
class Season {
    // 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;
    }
    
    // 3.提供当前枚举类的多个对象：public static final的
    public static final Season SPRING = new Season("春天", "春暖花开");
    public static final Season SUMMER = new Season("夏天", "夏日炎炎");
    public static final Season AUTUMN = new Season("秋天", "秋高气爽");
    public static final Season WINTER = new Season("冬天", "冰天雪地");
    
    // 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 + "]";
    }
}
