我在猜猜游戏.JTextField不能为空,不能长于或小于5且不能包含数字.我该怎么做最后一部分？

@Override
public void actionPerformed(ActionEvent e) {
    if (text.getText().isEmpty()) {
        showErrorMessage("You have to type something");
    } else if (text.getText().length() != 5) {
        showErrorMessage("Currently only supporting 5-letter words");
    } else if (contains integer){
        showErrorMessage("Words don't contain numbers!");
    } else {
        r.setGuess(text.getText());
    }
}
