这篇博客介绍了如何在Java中定义和使用枚举类，包括使用enum关键字创建枚举类型，以及自定义枚举类的方式。通过示例展示了如何为枚举类设置属性和构造器，并创建枚举对象。

//使用enum定义枚举类
enum Season1 {
    //创建对象
    SPRING("春天","春暖花开"),
    SUMMER("夏天","夏日炎炎"),
    AUTUMN("秋天","秋高气爽"),
    WINTER("冬天","含风凌烈");
    //定义属性
    private final String seasonName;
    private final String seasonDesc;
    //私有化构造器
    private Season1(String seasonName,String seasonDesc){
        this.seasonName=seasonName;
        this.seasonDesc=seasonDesc;
    }
}

//自定义枚举类
public class Season {
    //定义类的属性
    private final String seasonName;
    private final String seasonDesc;
    //私有化构造器
    private Season (String seasonName,String seasonDesc){
        this.seasonName=seasonName;
        this.seasonDesc=seasonDesc;
    }
    //创建几个对象
    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","含风凌烈");
}
