Answer 1

i am written some code see this public void actionPerformed(ActionEvent e) {
// Handle open button action.
if (e.getSource() == browse) {
int returnVal = fc.showOpenDialog(NnsClient.this);
if (returnVal == JFileChooser.APPROVE_OPTION ) {
File file = fc.getSelectedFile();
// This is where a real application would open the file.
log.setText(file.getParent());
} else {
log.setText("Open command cancelled by user." + newline);
log.setCaretPosition(log.getDocument().getLength());
// Handle update button action.
} else if (e.getSource() == update) {
File file = fc.getSelectedFile();
String val = file.getAbsolutePath();
File file1 = new File (val);
try
RandomAccessFile ra = new RandomAccessFile(file1,"r");
//System.out.println(ra);
long last = ra.length();
System.out.println(last);
FileReader fis = new FileReader (file1);
//LineNumberReader lr = new LineNumberReader(fis);
//System.out.println(lr);
//lr.skip(last);
//int countRec = lr.getLineNumber()-1;
//System.out.println(countRec);
BufferedReader bis = new BufferedReader(fis);
StringBuffer sb = new StringBuffer();
String line = null;
while((line= bis.readLine())!=null)
     //int i = line.length();
     System.out.print(line.toString());
     //System.out.println(line);
     //sb.append(line);
System.out.println(sb.append(line));
     sb.append("\n");
tf.setText(sb.toString());
ra.close();
fis.close();
//dis.close();
bis.close();
catch(FileNotFoundException e2)
e2.printStackTrace();
catch(IOException e1)
e1.printStackTrace();
}this is for action performed in this code only i want to develop that when i click on update i wanto get the file data on different tabs
JTabbedPane tp = new JTabbedPane();
JPanel pa = new JPanel();
pa.add(scroll);
//pa.add(ns.ta.setText(sb.toString()));
JPanel pb = new JPanel();
pb.add(tf);
t.setEditable(false);
//setPrefferedSize(new Dimension(30,40));
//tf.setText(sb.toString());
tp.addTab("tab1", pb);
tp.addTab("tab2",pa);
content.add(tp,BorderLayout.SOUTH);this code is for tabbedpanes on my program
