JTable to txt File

[Tzaphiel]

Hi - I am relatively new to Java and was wondering if anyone could help me with the following issue. I am trying to write a JTable to a txt file, and have the JTable also be able to read the txt file. The problem is that it is writing the letters with a square symbol between each of them and therefore is unable to then read them back into the JTable. Here is my code for saving the file.

Thanks!

	public void saveFile() {
		File file = null;
		JFileChooser fc = new JFileChooser();
		fc.setCurrentDirectory (new File ("."));
		int result = fc.showSaveDialog (this);
		if (result == JFileChooser.APPROVE_OPTION) {
			file = fc.getSelectedFile();
			if (file.exists ()) {
				int response = JOptionPane.showConfirmDialog (null,
					"Overwrite existing file?","Confirm Overwrite",
				JOptionPane.OK_CANCEL_OPTION,
				JOptionPane.QUESTION_MESSAGE);
				FileOutputStream fos; 
				DataOutputStream dos;
				    try {
				      fos = new FileOutputStream(file);
				      dos = new DataOutputStream(fos);
				      for (int i = 0; i < Billing.data[0].length; i++){;
				    	  dos.writeChars(table.getValueAt(i, 0).toString().trim());
				    	  dos.writeChars("\t");
				    	  dos.writeChars(table.getValueAt(i, 1).toString().trim());
				    	  dos.writeChars("\t");
				    	  dos.writeChars(table.getValueAt(i, 2).toString().trim());
				    	  dos.writeChars("\t");
				    	  dos.writeChars(table.getValueAt(i, 3).toString().trim());
				    	  dos.writeChars("\t");
				    	  dos.writeChars(table.getValueAt(i, 4).toString().trim());
				    	  dos.writeChars("\t");
				    	  dos.writeChars(table.getValueAt(i, 5).toString().trim());
				    	  dos.writeChars("\n");
				      } // end for
				    } // end try
			    	catch (IOException e) {
			    		System.err.println(e.getMessage());
			    	} // end catch
            } // end inner if
        else fc.cancelSelection();
		} // end outer if
	} // end method saveFile

try using WriteBytes instead of WriteChars. It might work because it worked for me:)
