java - 如何将枚举类型添加到具有普通实例变量的类中？

Question

public class Car
{

    public enum User { "user", "computer", "na" };

    private char car;
    private final User user;
    private boolean call;

    public Car(char object, User user, boolean call)
    {
        this.car = car;
        this.user = user;
        this.call = call;
    }

        public User getUser()
        {
        return user;
        }

    public void setUser(User user)
    {
        this.user = user;
    }

}

当我尝试编译时，我得到以下信息:

错误:预期

错误:“,”、“}”或“;”预计

错误:应为“}”

不要使用引号:

public enum User { user, computer, na };
