一篇文章让你三分钟学会Java枚举

/**
 * 创建枚举对象
 * 注意事项：
 * 一：定义枚举类型
 * 二：定义私有变量（私有变量的数量取决于枚举类型括号里面的参数数量）
 * 三：重载构造方法
 * 四：编写get/set方法
 */
public enum MyEnumDemo {

 //一：定义枚举类型
 HELLO("hello","1","haha1"),
 WORLD("world","2","haha2"),
 OTHER("other","3");

 //二：定义私有变量（私有变量的数量取决于枚举类型括号里面的参数数量）
 private String demo1;
 private String demo2;
 private String demo3;

 //三：重载构造方法
 MyEnumDemo(String demo1, String demo2) {
 this.demo1 = demo1;
 this.demo2 = demo2;
 }

 //三：重载构造方法
 MyEnumDemo(String demo1, String demo2, String demo3) {
 this.demo1 = demo1;
 this.demo2 = demo2;
 this.demo3 = demo3;
 }

 //四：编写get/set方法
 public String getDemo1() {
 return demo1;
 }

 public void setDemo1(String demo1) {
 this.demo1 = demo1;
 }

 public String getDemo2() {
 return demo2;
 }

 public void setDemo2(String demo2) {
 this.demo2 = demo2;
 }

 public String getDemo3() {
 return demo3;
 }

 public void setDemo3(String demo3) {
 this.demo3 = demo3;
 }

}

import org.junit.Test;

public class Demo {

 @Test
 public void hah(){
