如何在开关盒中使用枚举

Question

我正在尝试检查我的VO中设置的值.

以下是我的clasess.我得到" 合格的案例标签MyEnum.UserType.DOCTORS必须用不合格的枚举常量DOCTORS替换 "

请帮我识别我在这里做错了什么.

MyEnum.java

public MyEnum{
    private UserType userType;

    public UserType getUserType(){
        return userType;
    }

    public void setUserType(UserType userType){
        this.userType = userType;
    }

    public static enum UserType{
        DOCTORS("D"),
        PATIENT("P"),
        STAFF("S");
    }

}

EnumTest.java

public EnumTest {

    .....
    public void onGoBack(MyEnum myEnum) {

        switch(myEnum.getUserType())
        {
            case UserType.DOCTORS: // this shows "The qualified case label MyEnum.UserType.DOCTORS must be replaced with the unqualified enum constant DOCTORS"
                break;

        }
    }

}
