Edit table cells

Question

i have edited the setValueAt method of the TableModel interface to enable editing of cells in my JTable - in-situ. This works fine. However, i would like it so that when any change is made to the table data, it is automatically sorted depending on how it was sorted before the change was made. i have:
public void setValueAt(Object aValue, int row, int col) {
        if (col == 0) {
            bookList[row].setBookNumber(Integer.parseInt((String)aValue)); // Populates cell with new book number
            if (lastSort == "number") {
                listByNumber();
        } else {
            if (col == 1) {
                bookList[row].setTitle((String)aValue); // Populates cell with new book title
            } else {
                if (col == 2) {
                    bookList[row].setAuthorPrename((String)aValue); // Populates cell with new author prename
                } else {
                    bookList[row].setAuthorSurname((String)aValue); // Populates cell with new author surname
    }i would put more if statements in later for different sort methods but at the moment ill just stick with one. My problem is that the array is being sorted correctly, but the table doesn't update automatically to show the change. what DOES happen - is when you click on each row of the table, it changes until it is in the correct order. this leads me to think that the sorting works fine, but somehow my table model isnt reflecting the changes? can any help me update the table in real time?

Answer 1

no luck :( i tried:
   public void setValueAt(Object aValue, int row, int col) {
        if (col == 0) {
            bookList[row].setBookNumber(Integer.parseInt((String)aValue)); // Populates cell with new book number  
            listByNumber();
            fireTableDataChanged();and extended AstractTableModel but it still didnt work. is there anything else i would need to do?
