In my application ,i am using jTable.
jTable consist of four column.
At fourth column ,check box is being added,during run time.

So now the problem description.
Suppose in database table there are four records,i get those records,
and set them in jTable,with corresponding check box.

So now in jtable there are four records as well as four corresponding check box.

next ,when in table there are only two records,programtically i will get
those records, set them again in jtable ,but now this time two records are
set in jtable ,with corresponding check box,but the next two other rows
also contain the check box.

so please write, what could be the problem

How are you "setting" them in the table? Do you have a customized table model which holds the data?
Usually, when you tweak the model, you also need to fire the fireTableDataChanged() for the changes to be reflected in the table.
If you can post the "set them in the table" code, we can try and identify what is going wrong.
