I am new in Java programming language and I know that there are four platforms of the Java programming language
Java Platform, Standard Edition (Java SE)
Java Platform, Enterprise Edition (Java EE)
Java Platform, Micro Edition (Java ME)
I already read about the four platforms through the below link
But what I want to make sure of it by experts here that Java EE has more packages than Java SE and Java ME has less packages than Java SE and definitely than Java EE. Also I need to know where can I find a list of these different packages.
I've downloaded the Java SE Development Kit from the linke below
I've download the Eclipse IDE also. Can I write application(s) that connects to database or I have to download the Java EE SDK as it contains packages which in turn contains the classes by which I can connect to the database and execute queries etc. and these packages do not exist in Java SE SDK, and the same question if I want to write application(s) for a mobile device(s) do I have to download the Java ME SDK or I can begin write such application(s) without the need to download these SDK(s)?
Thanks in advance
