(JTable) How can i get the first columns cell in a selected row?

Question

Hello. I am trying to figure out how i can get the first columns cell within a selected row no matter what cell is selected in that row. I have a class that extends AbstractTableModel which represents the table. Now i have another class that extends DefaultSelectionModel. Each model is added to the JTable via setModel(TableModel dataModel), setSelectionModel(ListSelectionModel newModel). Now i don't understand what i have to return from getMaxSelectionIndex(). Any ides? Thanks.
  class xTableModel extends AbstractTableModel{
     private static String[] cols;
     private Object[][] data;
        public void setTableModel(Object data[][], String[] cols){
         this.cols = cols;
         this.data = data;
        public String getColumnName(int col){
         return cols[col];
        public int getRowCount() {
         return data.length;
        public Object getValueAt(int row, int col) {
         return data[row][col];           
        public void setValueAt(Object value,int row,int col){
         data[row][col]=value;
        public int getColumnCount(){
         return cols.length;
class ColumnListenerModel extends DefaultListSelectionModel{
     public int getMaxSelectionIndex(){}

Answer 1

int row = table.getSelectedRow();
Object data = table.getValueAt(row, 0);
