I am now able to programmatically read each cell and also write to each cell.
For example, to set a value at cell 5, 5:
mytable.setValueAt("cc",5,5);
where mytable is a JTable object
To read a value from cell 5,5 :
String myvalue = (String)mytable.getValueAt(5, 5);
To be done:
Next I will implement code to save the contents of each cell in this xml format:
where PC, JM and SK are example Lecturer's names.
I will also need to implement code to enable user to populate the JTable with any selected xml file of the above format.
