The argument is an integer giving the width of the TextField in characters.

TextFields have methods either to get the text that a user typed in, or to write some text in the box: String word1 = tf.getText ( ) ; tf.setText ( "Thanks!" ) ;

Note that when the user presses enter, a TextField can also generate an ActionEvent, but it is generally better user design to respond to button events.
