What is the suitable way to close the database connection in Java?

Question

I tried to close the DB connection.But had a bit of confusion, say

ResultSet rs = null 

Whether I have to it close by

rs.c         


        

Answer 1

I think the best way is do everything within a try-with-resources

try(conn=openConnection()){
  try(rs=conn.getResultSet()){
  }
}

So that you be entirely sure the resources will be properly closed at the end.
