Swing – Thread.sleep() stop JTextField.setText() working [duplicate]

by

When you use Thread.sleep() you’re doing it on the main thread. This freezes the gui for five seconds then it updates the outputField. When that happens, it uses the last set text which is blank.

It’s much better to use Swing Timers and here’s an example that does what you’re trying to accomplish:

if (match) {
    // Another class calculates
} else {
    outputField.setText("INPUT ERROR");
    ActionListener listener = new ActionListener(){
        public void actionPerformed(ActionEvent event){
            outputField.setText("");
        }
    };
    Timer timer = new Timer(5000, listener);
    timer.setRepeats(false);
    timer.start();
}
