Answer 1

        for (int i=0;i<jTable1.getRowCount();i++) {
            for (int j=0;j<jTable1.getColumnCount();j++) {
                Object value = jTable1.getValueAt(i,j);
                System.out.println(
                        " row="    + i +
                        " column=" + j +
                        " value="  + ( value != null ? value : "null" )
            System.out.println("");
        }
