title: Why FileWriter doesn't create a new file?
body: <p>Consider the following code:  </p>
  
  <pre><code> m_Writer = new PrintWriter(new FileWriter("LoginHistory.dat")); 
   m_Writer.println(Integer.toString(s_NumOfLogins)); 
   m_Writer.println(m_LoginHistoryStr);
   m_Writer.close();   
  </code></pre>
  
  <p>Any ideas why I don't find any file called LoginHistory.dat?<br>
  Thanks</p>
  
  <p>Update: I've just found that I get an exception after line:  </p>
  
  <pre><code>m_Writer = new PrintWriter(new FileWriter("LoginHistory.dat"));
  </code></pre>
  
  <p>and its details are:<br>
  Any ideas what is the real problem?    </p>
