• 自定义枚举


    1、方式一、自定义一个枚举类

    public enum Birds {
        WU_YA(1, "小乌鸦", 3),
        ZHUO_MU_MIAO(2, "啄木鸟", 2),
        XI_QUE(3, "喜鹊", 5);
    
        private Integer id;
        private String name;
        private Integer age;
    
        Birds(Integer id, String name, Integer age) {
            this.id = id;
            this.name = name;
            this.age = age;
        }
    
        public Integer getId() {
            return id;
        }
    
        public String getName() {
            return name;
        }
    
        public Integer getHeight() {
            return age;
        }
    }
    

      

    2、方式二、自定一个接口,然后接口中定义枚举类型

    public interface Organism {
        /**
         * 自定义 Animal 枚举类
         */
        enum Animal{
            ELEPHANT(11,"大象",6000),
            HIPPO(22,"河马",3000),
            LION(33,"狮子",400);
    
            private Integer id;
            private String name;
            private Integer weight;
    
            Animal(Integer id,String name,Integer weight){
                this.id=id;
                this.name=name;
                this.weight=weight;
            }
    
            public Integer getId() {
                return id;
            }
    
            public String getName() {
                return name;
            }
    
            public Integer getWeight() {
                return weight;
            }
        }
    
        /**
         * 自定义 Plant 枚举类
         */
        enum Plant{
            LOTUS(111,"荷花","红色"),
            PENOY(222,"牡丹","白色"),
            ROSE(333,"玫瑰","蓝色");
    
            Plant(Integer id,String name,String color){
                this.id=id;
                this.name=name;
                this.color = color;
            }
    
            private Integer id;
            private String name;
            private String color;
    
            public Integer getId() {
                return id;
            }
    
            public String getName() {
                return name;
            }
    
            public String getColor() {
                return color;
            }
        }
    }
    

      

    3、测试

    public class TestEnums {
        public static void main(String[] args) {
            System.out.println(Birds.WU_YA.getId()+"---"+Birds.WU_YA.getName()+"---"+Birds.WU_YA.getHeight());
            System.out.println(Birds.XI_QUE.getId()+"---"+Birds.XI_QUE.getName()+"---"+Birds.XI_QUE.getHeight());
            System.out.println(Birds.ZHUO_MU_MIAO.getId()+"---"+Birds.ZHUO_MU_MIAO.getName()+"---"+Birds.ZHUO_MU_MIAO.getHeight());
    
            System.out.println(Organism.Animal.ELEPHANT.getId()+"---"+Organism.Animal.ELEPHANT.getName()+"---"+Organism.Animal.ELEPHANT.getWeight());
            System.out.println(Organism.Animal.HIPPO.getId()+"---"+Organism.Animal.HIPPO.getName()+"---"+Organism.Animal.HIPPO.getWeight());
            System.out.println(Organism.Animal.LION.getId()+"---"+Organism.Animal.LION.getName()+"---"+Organism.Animal.LION.getWeight());
    
            System.out.println(Organism.Plant.LOTUS.getId()+"---"+Organism.Plant.LOTUS.getName()+"---"+Organism.Plant.LOTUS.getColor());
            System.out.println(Organism.Plant.PENOY.getId()+"---"+Organism.Plant.PENOY.getName()+"---"+Organism.Plant.PENOY.getColor());
            System.out.println(Organism.Plant.ROSE.getId()+"---"+Organism.Plant.ROSE.getName()+"---"+Organism.Plant.ROSE.getColor());
        }
    }
