Repeat after Me

Here an application that has two JTextFields. The user types into one field and hits enter. The application then copies text from that field to the other.

In the picture, the user typed in "Sherlock" and then hit enter. Here is an applet that does much the same thing. Swing components work in applets as well as applications.

Type your name in the first field then hit enter to see it echoed to the second field. The code for the applet is nearly the same as the code for the application.
