Java浅析枚举类的使用

package com.meijulei;
//枚举类
public enum Cat {
    A("小明",12),B("小花",22),C("小红",23),D("小蓝",30),E("小绿",20),F("小黄",32);
    public String name;
    private int age;
    private Cat(){
    }
    private Cat(String a,int b){
        name=a;
        age=b;
    }
    public void m1(){
        System.out.println("姓名为:"+name+",年龄为:"+age);
    }
}
//调用
package com.meijulei;
import com.meijulei.Cat;
public class Test {
    public static void main(String[] args) {
        Cat a=Cat.A;
        a.m1();
    }
}

A("小明",12),B("小花",22),C("小红",23),D("小蓝",30),E("小绿",20),F("小黄",32);
		System.out.println(Cat.E.ordinal());
        System.out.println(Cat.C.compareTo(Cat.E));

public class Enum {
    public static void main(String[] args) {
        System.out.println(Season.spring);
        System.out.println(Season.SUMMER);
        System.out.println(Season.AUTUMN);
        System.out.println(Season.WINTER);
    }
}

// 定义的枚举类
enum Season {
    // 枚举定义的常量对象必须在最前面
    SPRING("春天","万物复苏"),
    SUMMER("夏天","烈日炎炎"),
    AUTUMN("秋天","硕果累累"),
    WINTER("冬天","寒冷刺骨");

    private String name;
    private String desc;

    private Season(String name, String desc) {
        this.name = name;
        this.desc = desc;
    }

    public String getName() {
        return name;
    }

    public String getDesc() {
        return desc;
    }

    @Override
    public String toString() {
        return "Season{" +
                "name='" + name + '\'' +
                ", desc='" + desc + '\'' +
                '}';
    }
}

// 枚举定义的常量对象必须在最前面
SPRING("春天", "万物复苏"),
SUMMER("夏天", "烈日炎炎"),
AUTUMN("秋天", "硕果累累"),

Other, Shit;
