У меня есть фрагмент кода, который устанавливает ListModel на основе содержимого файла и добавляет его в jList.Код работает правильно, когда я выбираю файл в первый раз.Когда я выбираю второй файл, он дает исключение Array Out of Bounds.Ошибка происходит в runList.setModel (модель);
Вот код
protected class OpenFileListener implements ActionListener
{
@Override
public void actionPerformed(ActionEvent ae) {
try
{
JFileChooser fileChooser = new JFileChooser();
fileChooser.setFileFilter(new FileNameExtensionFilter("*.txt", "txt"));
fileChooser.setCurrentDirectory(new File("."));
int result = fileChooser.showOpenDialog(null);
fileName = fileChooser.getSelectedFile().getPath();
molfindOutText.setText(getFileName());
DefaultListModel model = new DefaultListModel();
runList.setModel(model);
File f = new File(getFileName());
Scanner scanner = new Scanner(f);
lineNo = 0 ;
int i = 0;
idLines = new ArrayList();
while (scanner.hasNextLine())
{
String line = scanner.nextLine();
lineNo = lineNo+1;
if (line.matches(".*COMPOUND_IDENTIFICATION_RUN.*"))
{
model.add(i, line);
runList.setSelectedIndex(0);
idLines.add(lineNo);
i++;
}
}
currentRun = 1;
if (idLines.size()>1)
{
extractRunInfo(idLines.get(0),idLines.get(1)-2);
}
else
{
extractRunInfo(idLines.get(0),lineNo);
}
scanner.close();
runList.addListSelectionListener(lsl);
}
catch(Exception e)
{
System.out.println(e.toString());
}
}
