Java枚举 - lvym777

自定义枚举：

使用enum定义枚举类：


定义有参枚举 ：

 1 public enum TestEnum {
 2     
 3     SPRING("春天","春风又绿江南岸"),
 4     SUMMER("夏天","映日荷花别样红"),
 5     AUTUMN("秋天","秋水共长天一色"),
 6     WINTER("冬天","窗含西岭千秋雪");
 7     private final String seasonName;
 8     private final String seasonDesc;
 9     private TestEnum(String seasonName, String seasonDesc) {
10         this.seasonName = seasonName;
11         this.seasonDesc = seasonDesc;
12     }
13     public String getSeasonName() {
14         return seasonName;
15     }
16     public String getSeasonDesc() {
17         return seasonDesc;
18     }
19     
20     
21 
22 }

test：

1 public static void main(String[] args) {
2         String f=TestEnum.SPRING.getSeasonName();
3                 if (f=="春天") {
4             System.out.println("HELLO："+f);
5         }
6         
7     }

枚举参一：

 1 public enum TestEnum {
 2     
 3     SPRING("春天"),
 4     SUMMER("夏天"),
 5     AUTUMN("秋天"),
 6     WINTER("冬天");
 7     private final String seasonName;
 8     
 9     private TestEnum(String seasonName) {
10         this.seasonName = seasonName;
11     }
12     public String getSeasonName() {
13         return seasonName;
14     }
15     
16 }

test同上。。。。

枚举无参：

1 public enum TestEnum {
2     
3     SPRING,
4     SUMMER,
5     AUTUMN,
6     WINTER;
7     
8 }
