In the method where you call the calculations method, wrap the call in this:

    public void actionPerformed(ActionEvent e){      
    Thread t = new Thread(new Runnable() {
        public void run() {
            try {
                label2.setText(bracket(splitLabel(label.getText())));
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });
    t.start();
    }
