Different ways of creating objects?

Hi All,

I am new to Java and am studying a text book on the subject.

I have come across the following two lines of code; each of which creates a new object -

Calendar cal = Calendar.getInstance();

Date now = new Date();

I have a reasonable understanding of the 'new' keyword, and it's relationship to creating objects.

However I am wondering if anybody can explain to me, or point me in the direction of a good resource, which thoroughly explains why some objects are created with dot(.) notation, e.g.: Calendar.getInstance();, and others are created with the 'new' keyword? I am anticipating that the difference will relate to 'System' classes, but I have no idea of what these actually are!

Any help here would be greatly appreciated.

Kind Regards,

Davo
