Why use finally instead of code after catch [duplicate]

Answer 1

The finally block may not always run, consider the following code.

public class Tester {
    public static void main(String[] args) {
        try {
            System.out.println("The main method has run");
            System.exit(1);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            System.out.println("The finally block has run");
        }
    }
}

In your case, I would suggest to wrap the code inside finally block into try/catch, as this code apparently may throw an exception.

    } catch (SQLException sqle) {
        sqle.printStackTrace();
    } finally {
     try {
        cs.close();
        rs.close();
     } catch (Exception e) {
      //handle new exception here
    }
