枚举类型总结

1. 枚举类型总结

public enum OperationEnum {

        LOGIN;   // 登录
        
    }

　　　　 int ordinal = OperationEnum.valueOf("LOGIN").ordinal();
        String name = OperationEnum.valueOf("LOGIN").name();
        
        System.out.println(ordinal);   // 0
        System.out.println(name);      // LOGIN

2.  枚举类型举例2

int ordinal = ATTRIBUTE_TYPE.valueOf("AGREEMENT").ordinal();  // 1
int ordinal2 = ATTRIBUTE_TYPE.AGREEMENT.ordinal();            // 1

System.out.println(ordinal);   //  1
System.out.println(ordinal2);  // 1

String name = ATTRIBUTE_TYPE.valueOf("AGREEMENT").name();  // AGREEMENT
String name2 = ATTRIBUTE_TYPE.AGREEMENT.name();　　　　　　　// AGREEMENT

System.out.println(name);      // AGREEMENT
System.out.println(name2);     // AGREEMENT

String getValue = ATTRIBUTE_TYPE.AGREEMENT.getValue();  // readc
String value = ATTRIBUTE_TYPE.AGREEMENT.value;　　　　　 // agreementc

System.out.println(getValue);  // readc
System.out.println(value);     // agreementc

ATTRIBUTE_TYPE attribute_type = ATTRIBUTE_TYPE.AGREEMENT;  //AGREEMENT

System.out.println(attribute_type);   //  AGREEMENT

public enum ATTRIBUTE_TYPE {
        READ("readCount"),
        AGREEMENT("agreementCount");

　　　　 private final String value;

        ATTRIBUTE_TYPE(String value) {
            this.value = value;
        }

        public String getValue() {
            return value;
        }
    }

枚举增加方法

    public enum ClickType{
        ACTIVITY_BUTTON_EARN("activity_button_1"),
        ACTIVITY_BUTTON_TOO("activity_button_2"),
        ACTIVITY_BUTTON_UNDERSTAND("activity_button_3");

        String type;

        ClickType(String type){
            this.type = type;
        }

        public static boolean isExist(String type){
            if(StringUtils.isBlank(type)){
                return false;
            }
            ClickType[] values = ClickType.values();
            for(ClickType clickType : values){
                if(clickType.type.equals(type)){
                    return true;
                }
            }
            return false;
        }
    }
