Format output of Buffered writer string
<p>I have the following code:</p>

<pre><code>BufferedWriter buffWriter = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile)));
buffWriter.write("\"time\",\"x voltage\", z voltage \n");
</code></pre>

<p>Later on, I call buffwriter.write again:</p>

<pre><code>buffWriter.write("\"" + time[i] + "\",\"" + an_array[i] + "\", \"" + an_array2[i] + ",\n");
</code></pre>

<p>Everything is fine, except one really small thing. There is a " on the left side my an_array2 values. How do i get rid of this?</p>
