枚举类与注解2-使用enum关键字定义枚举类

使用enum定义枚举类

代码示例：

public class seasonTest1 {

    public static void main(String[] args) {

        Season1 summer = Season1.SUMMER;

        System.out.println(summer);//SUMMER

        System.out.println(summer.getClass());//class com.study.lele.Season1

        System.out.println(summer.getSeasonDesc());//hot

    }

}

//使用enum定义枚举类

//定义的枚举类默认继承Enum类，重写toString后，就不再继承Enum类了

enum Season1{

//1、提供当前枚举类的对象，用,间隔，最后一个用;

    SPRING("Spring","warm"),

    SUMMER("Summer","hot"),

    AUTOMN("Automn","cool"),

    WINTER("Winter","cold");

//2、声明Season对象的属性:private final来修饰

    private final StringseasonName;

    private final StringseasonDesc;

//3、私有化类的构造器

    private Season1(String seasonName, String seasonDesc){

    this.seasonName = seasonName;

    this.seasonDesc = seasonDesc;

}

}
