Java中的枚举

Java中的枚举:

package main.java.test.myenum;

/**
 * @ClassName : TestEnum2
 * @Author : YiBin
 * @CreateTime : 2018/9/7 16:03
 * @Version : 1.0.0
 */
public enum  TestEnum2 {
    SUCCESS("000000", "请求成功!"),
    UNKNOWN_ERROR("111111", "服务器异常!");

    private String code;
    private String message;

    TestEnum2(String code, String message) {
        this.code = code;
        this.message = message;
    }

    public String getCode() {
        return this.code;
    }

    public String getMessage() {
        return this.message;
    }
}

调用:

package main.java.test;

import main.java.test.myenum.TestEnum2;

/**
 * @ClassName : TestName1
 * @Author : YiBin
 * @CreateTime : 2018/9/7 14:09
 * @Version : 1.0.0
 */
public class TestName1 {
    public static void main(String[] args) {
        String a = TestEnum2.SUCCESS.getCode();
        System.out.println("a = " + a);

        String b = TestEnum2.UNKNOWN_ERROR.getMessage();
        System.out.println("b = " + b);
    }
}

输出结果:

a = 000000
b = 服务器异常!
