question on swings i.e delete button

[smart]

Hello, Good Morning every one i am new to work with swings i am facing
problem with delete button.

In an application i kept a button Delete . For delete button i have
taken ShowConfirmDialog i.e YES_NO_OPTION.

When i press YES it is deleting record which is correct. But when i
press NO button it is deleting record which is not happen. I used for
delete query is like this

[ pstmtdel=con.prepareStatement("delete from ICLASS where
Sno='"Sno"'"); ]

[ pstmtdel.executeUpdate();]

And try with if condition also when i put query in if condition it's
showing an error .

Error is variable pstmtdel might not have been initialized

So, how can solve this one. Help me regarding this topic


Thanks

Please provide the full code snippet you are referring to. I see no "if"
condition in the code snippet you provided, therefore it is impossible to
find out what your problem is.
