how to use an abstract class?

[stranger123]

Hi,

Can you explain how to use an abstract class? I want to use Calendar to find weekday but we cannot use
Calendar calendar = new Calendar(06,04,22)......

Thank you in advance.

Reading the first 10 lines of the api-doc would have shown:

Calendar rightNow = Calendar.getInstance();

Thank you.
Is that the method every abstract class can use to create an object of the class? Can you explain a little more about abstract class?

Can you explain a little more about abstract class?

Yes, I can, but I'm tired of repeating stuff you'll find in every book, in online-Tutorials and FAQs.

It's just to much to explain to be handled in an q&a-forum.
Here is one article which links to a second one:

If you have specific questions, or don't understand something, you're welcome.

That method can be used in every abstract class, which provides it. Most abstract classes don't.
