 |
|
I am trying to create code that enables the user to browse serially through a CSV file, however, the following doesn't work, any idea why?
| Code: |
public void //<editor-fold defaultstate="collapsed" desc="Opens content from the catalogue file">
openCatalogue (int skipRecords)
//</editor-fold>
throws IOException
{
int fieldNumber = 1 + skipRecords;
while ((fieldNumber + skipRecords > 0) &&
(fieldNumber <= FIELDS_PER_RECORD) &&
(aRecord.readFields(CURRENT_CATALOG_FILE, FIELD_DELIMITER) != null))
{
if (fieldNumber == (1 + skipRecords))
{
txtLocation.setText(aRecord.readFields(CURRENT_CATALOG_FILE, FIELD_DELIMITER).get(fieldNumber - 1));
}
else if (fieldNumber == 2 + skipRecords)
{
txtTitle.setText(aRecord.readFields(CURRENT_CATALOG_FILE, FIELD_DELIMITER).get(fieldNumber - 1));
}
else if (fieldNumber == 3 + skipRecords)
{
txtAuthor.setText((aRecord.readFields(CURRENT_CATALOG_FILE, FIELD_DELIMITER).get(fieldNumber - 1)));
}
else if (fieldNumber == 4 + skipRecords)
{
txtPublisher.setText((aRecord.readFields(CURRENT_CATALOG_FILE, FIELD_DELIMITER).get(fieldNumber - 1)));
}
else if (fieldNumber == 5 + skipRecords)
{
Integer musicType = Integer.parseInt(((aRecord.readFields(CURRENT_CATALOG_FILE, FIELD_DELIMITER).get(fieldNumber - 1))));
int musicTypeAsPrimitive = musicType.intValue();
cboMusicType.setSelectedIndex(musicTypeAsPrimitive);
}
else if (fieldNumber == 6 + skipRecords)
{
final short SECONDS_TO_MINUTES = 60;
Integer lengthInSeconds = Integer.parseInt(aRecord.readFields(CURRENT_CATALOG_FILE, FIELD_DELIMITER).get(fieldNumber - 1));
txtLengthInMins.setText("" + (lengthInSeconds / SECONDS_TO_MINUTES));
txtLengthInSeconds.setText("" + (lengthInSeconds % SECONDS_TO_MINUTES));
}
++fieldNumber;
} //end while
}
...
private void btnPreviousActionPerformed(java.awt.event.ActionEvent evt) {
try
{
this.openCatalogue(FIELDS_PER_RECORD * -1);
}
catch (IOException e)
{
System.out.println("DEBUG" + e.getMessage());
}
}
private void btnNextActionPerformed(java.awt.event.ActionEvent evt) {
try
{
this.openCatalogue(FIELDS_PER_RECORD);
}
catch (IOException e)
{
System.out.println("DEBUG" + e.getMessage());
}
}
