NX:Am I allowed to modify the "DBMain" interface?

[Sang-Wook Kim]

Hello,
I am working on the URLyBird and I have a question after having
a look at the interface "DBMain", which is the only given java
codes. Are we allowed to modify this interface such as by adding
more methods and more exceptions? I believe it is possible since
it's not written anywhere that we are not allowed to do so.
Thanks in advance for the reply!

My instructions state: "Your data access class must be called "Data.java", must be in a package called "suncertify.db", and must implement the following interface: ". So I'd say no, you can't modify it.

Nope(Its not advisable). If you want to add any helper methods and other exceptions, you can extend the given interface and add additional methods and exceptions to new interface.
A -- Sun provided interface.
B -- Your interface.
C -- Data class.
You can do somewhat like this...

interface A {
}
interface B extends A {
}
class C implements B {
}

You can add to B as you wish.
Good Luck

Dear Charlie, Satish,
Thank you for your replies! So I should leave "DBMain" as it is.
Thanks again and good luck!
