    Default Need line breaks in output display

    I have to get a list of entries from a text file to display in a JFrame. I was able to do that but everything is displaying on one line.

    How do I get it to display as it is listed in the text file?

    Here is what the text file contains:

    Rick Sebastian 49 Rick@home.com 813-111-2222
    John Doe 35 John@work.com 813-222-3333
    Peggy Bundy 50 Peggy@theoffice.com 813-333-4444
    Al Bundy 55 Al@thebar.com 813-444-5555
    Jane Doe 27 Jane@thebeach.com 813-555-6666

    Here is how it is displayed in the program:

    Here is the code I'm working with:

    package contact.display.info;
     
    import java.io.*;
    import javax.swing.*;
     
    /**
     *
     * @author Rick Sebastian
     */
    public class ContactDisplayInfo extends JFrame {
     
    JTabbedPane jtp1=new JTabbedPane();
    JPanel jp1=new JPanel();
    JTextArea t1=new JTextArea();
    ContactDisplayInfo () throws Exception
     
    {
            super("ContactDisplayinfo");
            FileReader f=new FileReader("C:/Users/Me/Documents/ContactInformationProgram/ContactInfo.txt");
            BufferedReader brk=new BufferedReader(f);       
            String s;
            while((s=brk.readLine())!=null){
            t1.append(s);
            }
            jp1.add(t1);
            jtp1.addTab("Tab1",t1);
            add(jtp1);  
            //setSize(400, 400);
            setLocationRelativeTo(null);
     
        }
        public static void main(String args[]) throws Exception
        {
            ContactDisplayInfo cdi=new ContactDisplayInfo();
            cdi.pack();
            cdi.setVisible(true);   
            cdi.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
        }
    }

    I set the frame size to 400 400 and that only changed the size of the frame. The text still extended out in one line. i know I need a word wrap of some sort, but I'm not sure how that's done, or how I would get it to group by individual entry. Ideally I would have 5 lines with 5 entries being displayed.

    Any help you can offer would be greatly appreciated!

    Rick

    Append a "\n" at the end of the line where you want the following data on the next line.

    In order to do that, I would have to modify the text file itself, no? If not, where would I put that in the code?

    Append the "\n" at the end of the String where you want the next String to go to the next line. The readLine() methods strips off the newline character when it reads a line from the file into a String. You need to put it back.
    If you don't understand my answer, don't ignore it, ask a question.

    Try this:
    If you need to print the output line by line you use this...

     while((s=brk.readLine())!=null){
            t1.append(s+"\n");
            }
