Delete records from a Table. Please help

Question

Hello Folks,
I have a table that contains 7 records with a Button to delete each record.
I am unable to delete any records from the table.
Please can some one just have a look into my class and tell me how
to delete a record from the table when the button is clicked.
You can also run this class from the your command Prompt
Just cut this and create a new java file.
Please assist.
