I've pretty much figured out all of the major issues I was having trouble with, thanks to the help from the people in these forums(thanks!). The info from my text file is displaying in the JTextArea but for some reason I can only get the last line of the file to display. There are 10 lines in the text file that I'm trying to display.

Here's my updated code:

public TextArea() { initComponents(); try { FileReader one = new FileReader ("info.txt"); BufferedReader buf = new BufferedReader(one); String line = ""; StringTokenizer st = null; int lineNumber = 0, tokenNumber = 0; //textArea.setText(line); while ((line = buf.readLine()) != null) { lineNumber++; //break comma separated line using "," st = new StringTokenizer(line, ","); while (st.hasMoreTokens()) { //display csv values tokenNumber++; line = ("Title: " + st.nextToken() + "\n" + "Make:" + st.nextToken() + "\n" + "Model:" + st.nextToken() + "\n" + "Year:" + st.nextToken() + "\n" + "Price:" + st.nextToken() + "\n" + "Notes:" + st.nextToken() + "\n" + "Details:" + st.nextToken() + "\n"); textArea.setText(line); } //reset token number tokenNumber = 0; //textArea.setText(line); } } catch (FileNotFoundException e) { JOptionPane.showMessageDialog(this, "File not found"); } catch (IOException e){ JOptionPane.showMessageDialog(this, "Data not read"); }

I'm trying to display some text in a JTextArea I have set up in a simple GUI. Easy right? That's what I thought, but I'm clearly not that advanced at Java. The hook is the information I want to display in the JTextArea is in a text file (file.txt).

Right now I have a main class and a class called TextArea that houses the GUI and two methods. In the main class I have set up a simple array with some text in it, and I'm able to get it to display in the JTextArea. Basically the code all works fine, the only thing I can't figure out and need to change is have the information in the array coming from a text file. So if anyone can help me figure this out I'd really appreciate it. And if there is another way to get a textfile to appear in JTextArea without putting it into an ArrayList first I'd love to know.

Here's my code for the Main class

package texttoarraylist; import java.util.*; import java.io.*; /** * * @author RJ */ public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { String dvds [] = {"text1", "text2"}; ArrayList myList = new ArrayList(); for (int sub = 0; sub < dvds.length; sub++){ myList.add(dvds[sub]); } TextArea one = new TextArea(); one.setVisible(true); one.setShowText(myList); } }

And here's the code for the TextArea Class

package texttoarraylist; /** * * @author RJ */ public class TextArea extends javax.swing.JFrame { /** Creates new form TextArea */ public TextArea() { initComponents(); } /** This method is called from within the constructor to * initialize the form. * WARNING: Do NOT modify this code.
