Enum枚举的使用

public enum XEnum {
    GENERATE(0), USE(1), STOP(2);
    
    private int value = 0;
    
    XfaqEwmSfyxEnum(int value){
        this.value = value;
    }
    
    public int value(){
        return this.value;
    }

}

 

枚举时通常添加一个int值，或者添加一个键值对 整数与字符串对应，如下：

public enum AdminTypeEnum {

    SYSTEM("系统管理员",1),
    AGENT("商会管理员",2);
    
    private final  int  val;
    private final  String desc;
    
    private AdminTypeEnum(String desc,int val) {
        this.val = val;
        this.desc = desc;
    }
    
  public static AdminTypeEnum getEnumType (int val) {
        for (AdminTypeEnum type : AdminTypeEnum.values()) {
                if (type.getVal() == val) {
                    return type;
                }
         }
         return null;
    }

    public int getVal() {
        return val;
    }

    public String getDesc() {
        return desc;
    }
}
