Question

Why do this

} catch (SQLException sqle) {
    sqle.printStackTrace();
} finally {
    cs.close();
    rs.close();
}

Instead of this

} catch (SQLException sqle) {
    sqle.printStackTrace();
}
rs.close();
cs.close();

Answer 1

Because if an exception gets thrown no code after the try block is executed unless the exception is caught. A finally block is always executed no matter what happens inside your try block.
