创建枚举类,以汽车为例
package com.lw.coodytest.enums; /** * @Classname CarTypeEnum * @Description 汽车类型枚举 * @Author lw * @Date 2020-01-08 11:32 */ public enum CarTypeEnum { CAR_TYPE_BMW("bmw", "宝马"), CAR_TYPE_BC("bc", "奔驰"), CAR_TYPE_AUDI("audi", "奥迪"); private String type; private String desc; private CarTypeEnum(String type, String desc) { this.type = type; this.desc = desc; } public static String getValue(String type) { CarTypeEnum[] carTypeEnums = values(); for (CarTypeEnum carTypeEnum : carTypeEnums) { if (carTypeEnum.type().equals(type)) { return carTypeEnum.desc(); } } return null; } public static String getType(String desc) { CarTypeEnum[] carTypeEnums = values(); for (CarTypeEnum carTypeEnum : carTypeEnums) { if (carTypeEnum.desc().equals(desc)) { return carTypeEnum.type(); } } return null; } private String type() { return this.type; } private String desc() { return this.desc; } }
测试代码
public static void main(String[] args) { // 根据类型获取描述 String desc = CarTypeEnum.getValue("bmw"); System.out.println("根据类型获取描述:" + desc); // 根据描述获取类型 String type = CarTypeEnum.getType("宝马"); System.out.println("根据描述获取类型:" + type); }
打印结果
java枚举类-根据key获取value及根据value获取key
