That error message suggests to me that you have code that's not inside a method or something. Post the code you are using (create an SSCCE as suggested in the other comment that demonstrates exactly what you are doing) — Goibniu, Oct 02 '13 at 10:58
.. 2) `lblA.setBounds(91, 68, 46, 14);` Java GUIs might have to work on a number of platforms, on different screen resolutions & using different PLAFs. As such they are not conducive to exact placement of components. To organize the components for a robust GUI, instead use layout managers, or [combinations of them](http://stackoverflow.com/a/5630271/418556), along with layout padding & borders for [white space](http://stackoverflow.com/q/17874717/418556). — Andrew Thompson, Oct 02 '13 at 11:13

Place

final JLabel lblA = new JLabel("New label");

before

addWindowListener(new WindowAdapter() {
    @Override
    public void windowOpened(WindowEvent arg0) {

        lblA.setText("Hello Java"); // Error is here
    }
});

not after it and your syntax error should go away.
