Need Help in Swing

I have tried the below two ways

FIRST: String str = queryTextArea.getText();
final JTextArea textArea = new JTextArea();
textArea.setFont(new Font("Sans-Serif", Font.PLAIN, 12));
textArea.setText(str);
textArea.setCaretPosition(0);
JScrollPane scrollPane = new JScrollPane(textArea);
scrollPane.setPreferredSize(new Dimension(350, 150));
JOptionPane pane = new JOptionPane(scrollPane, JOptionPane.PLAIN_MESSAGE,JOptionPane.PLAIN_MESSAG E);
JDialog dialog = pane.createDialog(null, "Query");
dialog.setResizable(true);
dialog.setVisible(true);



String str = queryTextArea.getText();
final JTextArea textArea = new JTextArea();
textArea.setFont(new Font("Sans-Serif", Font.PLAIN, 12));
textArea.setText(str);
textArea.setCaretPosition(0);
JScrollPane scrollPane = new JScrollPane(textArea);
scrollPane.setPreferredSize(new Dimension(350, 150));
int res = JOptionPane.showConfirmDialog(null,scrollPane,"Que ry", JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE);
System.out.println( "showInputDialog: " + res );
if(res==0)
queryTextArea.setText(textArea.getText());


Please help in having a doc-Modal

Thanks

maybe try pulling out the final before the JTextArea's
