getting numbers and calculating them in jTable

[Joe Don]

Hey guys,what I am trying to do on jtable is when a user enters values of numbers in the table, by click of button, those numbers are calculated and display in another column. For example, 4 = 2 + 2 in a table.This means getting inputs from user and summing them up. My getRowCount() and getValueAt() methods don't seem to work for me recently. I hope this forum can do me some good. Thanks in advance.

Don't do any calculations in a JTable. Create a calculations class which does them

Thanks for your guide. I wrote a simple class that allows me to do that. I used the jTable swing component on the NetBeans IDE. Here is the simple class:

DefaultTableModel model = (DefaultTableModel)jTable1.getModel();
//int rows = jTable1.getRowCount();// not necessary here for now.
int a;
int b;
int c;

a=Integer.parseInt(textfield1.getText().trim();

b=Integer.parseInt(textfield2.getText().trim();
 c=a+b;

model.addRow(new Object[]{a,b,c});
