可能的重复:
将枚举类型添加到列表
I have an enum class:
我有一个枚举类:
public enum MyEnum {
ONE, TWO, THREE;
}
And in another class, MyClass.java, I want to have the following
在另一个类 MyClass.java 中,我想要以下内容
ArrayList<MyEnum> list;
is this possible? because I'm encountering some issues.

There should be no problem doing that.
这样做应该没有问题。
This code compiles fine:
这段代码编译得很好:
package example;
import java.util.ArrayList;
import java.util.List;
public class Example {
public static void main (String[] args) {
List<MyEnum> enums = new ArrayList<MyEnum>();
}
enum MyEnum { ONE, TWO, THREE;}
// no need for that ^ but added to match your question
}
