Question

我正在控制台应用程序上构建一个联系人管理器应用程序，我已经创建了一个联系对象类，但我不断收到错误： “联系人”类型已包含“ContactTypes”的定义。我不知道如何解决这个问题

class Contact
{

    //private member variables
    private String _firstName;
    private String _lastName;
    public ContactTypes _contactTypes;
    private String _phoneNumber;
    private String _emailAddress;




    //Public constructor that takes five arguments
    public Contact()
    {
        //Call the appropriate setter (e.g. FirstName) to set the member variable value
        /*GetFirstName = firstName;
        GetLastName = lastName;
        ContactTypes = contactTypes;
        GetPhoneNumber = phoneNumber;
        GetEmailAddress = emailAddress;*/

    }

Answer 1

您有两个具有相同名称的类成员：

public ContactTypes ContactTypes
enum ContactTypes { Family, Friend, Professional }

只需重命名其中一个。

或者，正如评论中所建议的那样，您可以将ContactTypes枚举定义移到Contact类之外。

Answer 2

您的类和枚举具有相同名称的ContactTypes。这就是您收到错误的原因。考虑重命名类。

类型''已包含''的定义
