我认为这是我的代码的有用块。：
private void initialize() {
frmInformacijaApieMuzikos = new JFrame();
frmInformacijaApieMuzikos.setResizable(false);
frmInformacijaApieMuzikos.setIconImage(Toolkit.getDefaultToolkit().getImage(KDVizualizuotas.class.getResource("/lt/kvk/i3_2/kalasnikovas_stanislovas/resources/Sidebar-Music-Blue-icon.png")));
frmInformacijaApieMuzikos.setTitle("Muzikos stiliai");
frmInformacijaApieMuzikos.setBounds(100, 100, 262, 368);
frmInformacijaApieMuzikos.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
txtStilius = new JTextField();
txtStilius.setBounds(10, 34, 128, 20);
txtStilius.setColumns(10);
JButton btnIekoti = new JButton("Ie\u0161koti");
btnIekoti.setBounds(146, 36, 89, 19);
btnIekoti.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
