请问如何在JTextArea中屏蔽回车换行？也就是我敲了回车不让换行。

//pls try.
import javax.swing.*;
import java.awt.*;
import java.awt.event.KeyEvent;

public class TestTextArea {
public static void main(String[] args) {
final JFrame frame = new JFrame(TestTextArea.class.getName());
frame.setDefaultCloseOperation(3);
final KeyStroke enterKey = KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0 );
JTextArea messageTextArea = new JTextArea(3,2) {
protected boolean processKeyBinding(KeyStroke ks, KeyEvent e, int condition, boolean pressed) {
if (ks.equals(enterKey)) return false;
return super.processKeyBinding(ks, e, condition, pressed);
}
};
messageTextArea.setEditable(true);
messageTextArea.setFont(new Font("Helvetica", Font.PLAIN, 14));
messageTextArea.setSelectedTextColor(Color.blue);
messageTextArea.setSelectionColor(Color.lightGray);
frame.getContentPane().add(messageTextArea);
SwingUtilities.invokeLater(new Runnable() {
public void run() {
frame.pack();
frame.setVisible(true);
}
});
}
}

//or try.
KeyStroke enter = KeyStroke.getKeyStroke("ENTER");
textArea.getInputMap().put(enter, "none");
