getEchoChar</H3>
<PRE>
public char <B>getEchoChar</B>()</PRE>
<DL>
<DD>Gets the character that is to be used for echoing.
 <p>
 An echo character is useful for text fields where
 user input should not be echoed to the screen, as in
 the case of a text field for entering a password.
 If <code>echoChar</code> = <code>0</code>, user 
 input is echoed to the screen unchanged.<DD><DL>

<DD>Sets the echo character for this text field.
 <p>
 An echo character is useful for text fields where
 user input should not be echoed to the screen, as in
 the case of a text field for entering a password.
 Setting <code>echoChar</code> = <code>0</code> allows 
 user input to be echoed to the screen again.<DD><DL>
