In my code I delete all rows when closing with the following code:
public void removeAllRows() {
System.out.println("Rowcount:\t" + this.getRowCount());
if ((this.getRowCount()-1) > 0) {
System.out.println("\nJetzt wird der Tabelleninhalt gelöscht\n");
for( int i = this.getRowCount()-1; i >= 0; i-- ) {
this.removeRow(i);
}
}
}
So now when I want to update the content with a refresh button with the following code:
line = 0;
BufferedReader br = null;
String linesplit;
try {
System.out.println("*** Einchecken-Tabellen-Daten werden geladen ***");
br = new BufferedReader(new FileReader("tableData.txt"));
while ((linesplit = br.readLine()) != null) {
System.out.println(linesplit);
// String aufsplitten
String[] arr = linesplit.split(";");
for (int i = 0; i < arr.length; i++) {
if (i < (arr.length - 1)) {
getCheckinModel().setUpdateValueAt(arr[i], line, i);
} else {
getCheckinModel().setUpdateLastValueAt(arr[i], line, i);
}
}
line++;
System.out.println("\n Setted in line" + line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
}
I receive the following error:

How can I create new rows after deleting them with the following method?
