枚举未提供预期结果

Question

public class A{

     public static final String CANDY = "yelow candy";
     public static final String CAKE = "cookie";

    public enum Yummy{
         CANDY, CAKE; 
    }

}

public class C {

   Yummy[] yummies = A.Yummy.values();

   for (Yummy yum : yummies){
          String yumString = yum.toString();
          System.out.println("yum =" + yumString);
   }

Answer 1

您定义了一个枚举“a.yummy”和两个字符串“a.candy”和“a.cake”。

它们根本没有联系。

您将希望删除字符串并添加https://stackoverflow.com/a/13291109/1041364这样的内容

public enum Yummy {
     CANDY("yelow candy"),
     CAKE("cookie");

     private String description;

     private Yummy(String description) {
         this.description= description;
     } 

     public String toString() {
         return this.description;
     }
}
