Result Set re assign issue.

Question

Just a novice question. I have a code like
ResultSet rs = psmt.executeQuery("some query here");
// perform iterate on rs.
rs = psmt.executeQuery("some other query here");
on finally,
rs.close();
My question is will it create two instance on rs and left one closed and another unclosed or will it close both the ResultSet?
Regards,
A.

The real question is on issuing finally {rs.close}, will it close both instance?No, it won't. close() is invoked on the currently referenced object. Which is why I pointed out that you should close resources when done with them. Before even thinking of assigning the same variable to another instance, and before the variable goes out of scope.
If you need two ResultSets in the same scope, use two variables. Than you can close both in the same finally block.
will it cause memory leak?Probably. I don't do JDBC, so I won't categorically say it will.
