address book next and previous buttons

Question

I'm making an address book and I need to cycle through my contacts. The contacts are imported from file and are read into the JTextFields as so:

name
phone
mobile
address

How do I go about doing this?

I've tried, it runs but the buttons do nothing.

edit: now using this:

           public void importContacts() 
           {
     try 
            {

             BufferedReader infoReader = new BufferedReader(new FileReader("../files/example.txt"));
            txtName   .setText(readLine(infoReader));
        txtPhone  .setText(readLine(infoReader));
        txtMobile .setText(readLine(infoReader));
        txtAddress.setText(readLine(infoReader));

            } 
            catch (IOException ioe) 
            {

            JOptionPane.showMessageDialog(null, ioe.getMessage());
        }

}

Answer 1

In your importContacts() method

you do :

 txtName.setText(Name.get(0));
 txtPhone.setText(Phone.get(0));
 txtMobile.setText(Mobile.get(0));
 txtAddress.setText(Address.get(0));

instead of .get(0) I think it should be .get(index) according to your code

--Edit--

or to avoid re-importing your contact here what your previous() method should be :

public void Previous()
            {
                    if (index > 0)
                    {
                            index--;
                    }
                    txtName.setText(Name.get(index));
                    txtPhone.setText(Phone.get(index));
                    txtMobile.setText(Mobile.get(index));
                    txtAddress.setText(Address.get(index));

            }

  public void Next()
            {
                    if(index < temp.size() - 1){
                 index++;
               }
                    txtName.setText(Name.get(index));
                    txtPhone.setText(Phone.get(index));
                    txtMobile.setText(Mobile.get(index));
                    txtAddress.setText(Address.get(index));

            }
