Question

See my method

public void removeRow(int[] selectedRow) {
    int len = selectedRow.length;
    for(int i=0; i<len; i++) {
        data.remove(selectedRow[i]);
    }
    fireTableDataChanged();
}

this is the error callstack

I am using static ArrayList data as data holder

Answer 1

The problem is that when you remove a row, your tables indices are adjusted/decremented on each remove resulting in the IndexOutOfBoundsException. You could remove the rows in reverse order to guard against this:

for (int i = selectedRow.length - 1; i >= 0; i--) {
   data.removeRow(selectedRow[i]);
}
