Question

Hello
ive managed to display the text file text in the console, but i want it to show up in the textArea component i have in a frame,
it seems to display the last character . in the text area
wheres the rest of the text...this was a lot easier in VB.NET
any help would be much appreciated
heres my code...
private void openButtonActionPerformed(java.awt.event.ActionEvent evt)  {//GEN-FIRST:event_openButtonActionPerformed
// TODO add your handling code here:
     FileNameExtensionFilter filter = new FileNameExtensionFilter("Text Files Only","txt");
     editorFileChooser.setFileFilter(filter);
     int returnVal = editorFileChooser.showOpenDialog(this);
     if (returnVal == JFileChooser.APPROVE_OPTION){
          System.out.println("You chose to open this file: " + editorFileChooser.getSelectedFile().getName());
          openFileName = editorFileChooser.getSelectedFile().getName();
          openFile = new File(openFileName);
          try {
               this.readFile = new FileReader(openFile);
          } catch (FileNotFoundException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          int inputCharacters;
     try {
     while ((inputCharacters = readFile.read()) != -1){
          System.out.print((char)inputCharacters);
          char[]CHARAARAY = {(char)inputCharacters};
          s3 = new String(CHARAARAY );
          this.editorTextArea.setLineWrap(true);
     this.editorTextArea.setText(s3.toString());
     readFile.close();
     catch(IOException ex){
          System.out.println();
}//GEN-LAST:event_openButtonActionPerformed

There was a basic problem in the logic of that code, that resulted in the assumption (by the JRE) that every file the user attempted to load, was located in the 'current directory'. It was fixed by abandoning the String based file name of the file, and instead setting openFile to the selected file in the chooser. I also demolished the loading code by replacing the JTextArea with a JEditorPane (much easier).
