This piece of code works fyn. But if I remove EventQueue.invokeLater() , first key that has been typed is not getting recoganised

   public static class ListenerDemo implements KeyListener
    {
    String userString = null;
    private String getUserTypedString(KeyEvent e)
    {
        return ((JTextField) e.getSource()).getText();
    }

    @Override
    public void keyTyped(final KeyEvent e) {
        EventQueue.invokeLater(new Runnable() {

            @Override
            public void run() {
                userString = ((JTextField) e.getSource()).getText();
                System.out.println("User str = " +userString);


            }
        });
    }

Input in JCombox : 1 , In keyTyped output is User str = 1

But, If I dont use EventQueue.invokeLater()

Input in Jcombobox which I type is 1 , but output is userTyped =

Then on typing 2, I get output as userTyped = 1

If all the events are handled by EDT thread , then is it mandatory to use EventQueue.invokeLater() . Why keyType is getting recoganised late?
