<DL>
<DD>Constructs a new text area with the specified text,
 and with the rows, columns, and scroll bar visibility
 as specified.
 <p>
 The <code>TextArea</code> class defines several constants
 that can be supplied as values for the
 <code>scrollbars</code> argument: 
 <code>SCROLLBARS_BOTH</code>, 
 <code>SCROLLBARS_VERTICAL_ONLY</code>, 
 <code>SCROLLBARS_HORIZONTAL_ONLY</code>, 
 and <code>SCROLLBARS_NONE</code>. Any other value for the 
 <code>scrollbars</code> argument is invalid and will result in 
 this text area being created with scrollbar visibility equal to 
 the default value of <A HREF="../../java/awt/TextArea.html#SCROLLBARS_BOTH"><CODE>SCROLLBARS_BOTH</CODE></A>.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>text</CODE> - the text to be displayed. If
             <code>text</code> is <code>null</code>, the empty
             string <code>""</code> will be displayed.<DD><CODE>rows</CODE> - the number of rows.  If
             <code>rows</code> is less than <code>0</code>,
             <code>rows</code> is set to <code>0</code>.<DD><CODE>columns</CODE> - the number of columns.  If
             <code>columns</code> is less than <code>0</code>,
             <code>columns</code> is set to <code>0</code>.<DD><CODE>scrollbars</CODE> - a constant that determines what
             scrollbars are created to view the text area.<DT><B>Since: </B><DD>JDK1.1</DD>
