Thread: extend a simple class Contacts to have a new parameter called favorites

Hi, I am a very beginner in Java. I have a simple class called contacts which is a class in a simple phonebook application. I would like to extend a class method to include an extra parameter in another class favorites. My attempt with my contact class below is giving errors. Can please someone help ?

************************************************** *****************************

/** *

// Contacts Class
 
 
 
public class Contacts {
 
    public String name;
    public String phoneNumber;
    public String nickname;
 
    public Contacts(String name, String phoneNumber) {
        this.name = name;
        this.phoneNumber = phoneNumber;
    }
 
     class Favorites extends Contacts 
      (String name, String phoneNumber,String nickname) {
        name = name;
        phoneNumber = phoneNumber;
        nickname = nickname;
     //
    }
 
    public String getName() {
        return name;
    }
 
    public String getPhoneNumber() {
        return phoneNumber;
    }
    public String getnickName() {
        return nickname;
    }
}

giving errors

Please copy the full text of the compiler's error message and paste it here.

See ending tag for proper coding:

to get highlighting and preserve formatting.

Sorry, I do not use BlueJ.
To use the compiler From the command line, Enter: javac Contacts.java

{ expected

The body of a class needs to be enclosed in {}s. Look at the Contacts class. It starts with:

public class Contacts {

and ends with a }

When that is fixed, the other errors will change because the compiler got lost when it did not find the { for the class's body.

I fixed the } issue but I still get errors now on the
class favourites which are basically the same as previous. Can you help please?

*********************************************

 
public class Contacts {
 
    public String name;
    public String phoneNumber;
    public String nickname;
 
    public Contacts(String name, String phoneNumber) {
        this.name = name;
        this.phoneNumber = phoneNumber;
   }
 
    public String getName() {
        return name;
    }
 
    public String getPhoneNumber() {
        return phoneNumber;
    }
    public String getnickName() {
        return nickname;
    }
 
      public class Favorites extends Contacts 
      (String name, String phoneNumber,String nickname) {
        name = name;
        phoneNumber = phoneNumber;
        nickname = nickname;
 
    }
}

The { goes after the class name. See the code for declaring the Contacts class:

public class Contacts {

What is the purpose of this line:

(String name, String phoneNumber,String nickname)

It looks like code for a constructor's or method's parameters.
Again look at the code in Contacts:

public Contacts(String name, String phoneNumber) {

See how the name of the class is before (...)

Did you write the code for the Contacts class or was it given to you to modify?
