如何在开关盒中使用枚举 [英] How to use enum in switch case

问题描述

我正在尝试检查我的VO中设置的值。

以下是我的契约。我正在获得
合格的案例标签MyEnum.UserType.DOCTORS必须用不合格的枚举常数DOCTORS 替换

请帮助我确定我在这里做错什么。

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 show必须用合格的case标签MyEnum.UserType.DOCTORS替换不合格的枚举常量医生
 break; 
 
} 
} 
 
} 
  

解决方案

阅读错误信息。

  switch（myEnum.getUserType（））
 {
 case DOCTORS：
 break; 
 
} 
  

I am trying to check what values are set in my VO.

Below are my clasess. I am getting "The qualified case label MyEnum.UserType.DOCTORS must be replaced with the unqualified enum constant DOCTORS"

Please help me to identify what I am doing wrong here.

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;

        }
    }

}

解决方案

Read the error message. It tells you exactly what to do.

switch(myEnum.getUserType())
{
    case DOCTORS: 
        break;

}
