<center><h1>22.29 The Class <code>java.io.FileNotFoundException</code></h1></center>
<a name="30116"></a>
A <code>FileNotFoundException</code> is thrown to indicate that no actual file could be
opened for a specified path name. See constructors <code>FileInputStream</code> (<a href="javaio.doc2.html#28248">§22.4.1</a>,
<a href="javaio.doc2.html#28256">§22.4.2</a>) and <code>FileOutputStream</code> (<a href="javaio.doc14.html#29510">§22.16.1</a>, <a href="javaio.doc14.html#29518">§22.16.2</a>).
<p><pre><a name="30129"></a>public class <code><b>FileNotFoundException</b></code> extends IOException {
<a name="30130"></a> public <code><b>FileNotFoundException</b></code>();
<a name="30131"></a> public <code><b>FileNotFoundException</b></code>(String s);

<p>
<a name="30134"></a>

as its error message string.

<p>
<a name="30136"></a>

reference to the error message string <code>s</code> for later retrieval by the <code>getMessage</code>
method <a href="javalang.doc20.html#3275">(§20.22.3)</a>.
