Modifying Text in a JTextArea Component</h3>
The text in a text area can be modified using the method described in
<a href="../javax.swing.text/EditTextField.html" class="eglink"><font size="-1"><b>e969</b> Modifying Text in a JTextComponent</font></a>. However, the text area
supports a similar set of convenience editing methods which are
demonstrated in this example.
<pre>
// Create the text area
JTextArea ta = new JTextArea(<font color="#0066ff"><i>"Initial Text"</i></font>);
// Insert some text at the beginning
int pos = <font color="#0066ff"><i>0</i></font>;
ta.insert(<font color="#0066ff"><i>"some text"</i></font>, pos);
// Insert some text after the 5th character
pos = <font color="#0066ff"><i>5</i></font>;
ta.insert(<font color="#0066ff"><i>"some text"</i></font>, pos);
// Append some text
ta.append(<font color="#0066ff"><i>"some text"</i></font>);
// Replace the first 3 characters with some text
int start = <font color="#0066ff"><i>0</i></font>;
int end = <font color="#0066ff"><i>3</i></font>;
ta.replaceRange(<font color="#0066ff"><i>"new text"</i></font>, start, end);
// Delete the first 5 characters
start = <font color="#0066ff"><i>0</i></font>;
end = <font color="#0066ff"><i>5</i></font>;
ta.replaceRange(null, start, end);
