Buen dia algun alma que me ayude, tengo un jtable y le agregue unos checkbox al final, deseo que al seleccionar por ejemplo 1° y 4ta fila estas sean sumadas y mostradas -- solo he logrado sumar el total de la columna pero no las que selecciono en el checkbox, como puedo hacer, tengo este codigo

double sumatoria1=0.0;
int totalRow= TablaDatos.getRowCount();
totalRow-=1;
for(int i=0;i<=(totalRow);i++)
{
double sumatoria= Double.parseDouble(String.valueOf(TablaDatos.getValueAt(i,2)));

sumatoria1+=sumatoria;



total.setText(String.valueOf(sumatoria1));
