btnNewButton = new JButton("ok"); btnNewButton.addActionListener(new ActionListener() { private String i; private String a; public void actionPerformed(ActionEvent arg0) { i = textField.getText(); a = "Abandon"; if(i == a){ lblNewLabel.setText("Abandon"); } } });

    Changing the text of the label must be performed in the swing event stream. Try this:

     public void actionPerformed(ActionEvent arg0) { SwingUtilities.invokeLater(() -> { if ("Abadon".equals(textField.getText())) lblNewLabel.setText("Abadon"); else myLabel.setText("my text"); }); }

    In general, you have an error in the code; strings should be compared using the equals method.
