how can i change variable value in initialize from jbutton event?

private void initialize() {
    frame = new JFrame();
    frame.setBounds(100, 100, 450, 300);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    scrollPane = new JScrollPane();
    frame.getContentPane().add(scrollPane, BorderLayout.WEST);
    JButton btnNewButton = new JButton("New button");
    frame.getContentPane().add(tes, BorderLayout.NORTH);
    int n = 6;
    btnNewButton.addActionListener(new ActionListener() {

        public void actionPerformed(ActionEvent arg0) {
    //here iwant to change n value
          }

    }  
        });
}

Put n as global, so it will be never deallocated. Then inside actionPerformed you can process n as you wish.

In your example n is local to initialize and so it will be lost after the function terminate.
