定义枚举操作类

定义枚举就好比一个常量类 避免一些魔法值
但是定义枚举还得注意些细节,记得 多个枚举用逗号隔开,最后分分号结束...
实例:

/*
 * 枚举类
 * @author   Sir.tang  
 * @date    2020/10/13 10:37
 */
public enum MenuEnum {
    ceshi("1","2"),
    ceshi1("2","2"),
    ceshi2("1","2"),
    ceshi3("1","2"),
    ceshi4("1","2"),
    ceshi5("1","2");

    String a;
    String b;

    MenuEnum(String a, String b) { this.a = a;this.b = b; }

    public String getA() { return a; }

    public void setA(String a) { this.a = a; }

    public String getB() { return b; }

    public void setB(String b) { this.b = b; }
}

枚举使用就和常量一样使用即可
示例:

 //枚举测试类
   @Test
   public void  ceshi(){
       System.out.println(MenuEnum.ceshi.getA());
       System.out.println(MenuEnum.ceshi.getB());
       System.out.println(MenuEnum.ceshi1.getB());
   }
