JTextArea Storing Each Line

I'm making an Address Book application, and I have the basic fields (name, age, phone numbers, etc.) and I have a JTextArea for placing miscellaneous comments, since I won't know how much info I need to add. It could be one line or hundreds.

I want to know if there is a way to store this data and place it back into the field when the contacts information is loaded. I could store the entire JTextArea as a String, but would that keep the correct formatting? Or save many Strings into an ArrayList or something similar.

Additionally, is there a method to save blocks of text as opposed to single lines? For example. I might want to store an URL, or I might want to store a 5-line poem the contact wrote. Obviously, storing the URL could take one line, but the poem would take 5 lines and therefore 5 Strings.

What seems like a decant storage solution? If my concept doesn't make sense, please comment and I'll try to make it more clear.

Saving it as a single String should fine, it will, normally, preserve newlines as well.

This will of course, depend on where you are storing it

It sounds to me like your address book app is asking a user to input simple values as you suggested and I'm assuming it is saving these values into a "Contact" object or something similar.

If this is the case, you can simply add a String comments; to the Contacts class and implement a getter and setter method accordingly.

Just get the data from the JTextField and store it into that Contact's comments variable.

Contact person = new Contact();
person.setComments(textArea.getText());

Something like that. Then you can reference the person.getComments() later on and print that back out to the TextField if thats what you want to do with it.
