    <p>Edit of my code and question, I changed the BufferedWriter to class object and initialized it </p> <pre><code>public static String filename = "frequencies.txt"; public static BufferedWriter bufferedWriter; { try { bufferedWriter = new BufferedWriter( new FileWriter( filename ) ); } catch ( IOException e ) { e.printStackTrace(); } } private void plot_Frequencies ( final ITraceDetails msg ) { byte[] signal = msg.getFieldValue( "_Decoder Message" ).data(); int[] frequencies = new int[ 32 ]; try { for ( int i = 0, j = 29; i &lt; frequencies.length; i++, j += 2 ) { int low = signal[ j ] &amp; 0xFF; int high = signal[ j + 1 ] &amp; 0xFF; frequencies[ i ] = low | ( high &lt;&lt; 8 ); this.Frequencies.add( createGTSXYDataItem( msg.getMsgIndex(), msg.getMsgIndex(), msg.getExtendedMid(), frequencies[ i ] ), false ); } write_Frequencies( frequencies, band_number, bufferedWriter ); } catch ( Exception e ) { e.printStackTrace(); } } private void write_Frequencies ( final int[] frequencies, final int band, final BufferedWriter writer ) throws IOException { try { // Start writing to the output stream System.out.print( Arrays.toString( frequencies ) ); System.out.print( "\n" ); writer.write( "Hello World" ); writer.write( Arrays.toString( frequencies ) ); writer.newLine(); } catch ( FileNotFoundException ex ) { ex.printStackTrace(); } catch ( IOException ex ) { ex.printStackTrace(); } } </code></pre> <p>Now it does not print anything to the file , it just create an empty frequencie.txt file</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
