What does this "..." do ?

Well, nothing really interesting... It's just some syntactic sugar. :P

It makes an array with the arguments. You can cast the code with 2, 3 or more arguments. Some sample code:

Database database = DatabaseFactory.getDatabase(
DatabaseFactory.SQLITE3, "/tmp/test.db", null, null);
String[] data = {"xephandor", "19"};
String[] data2 = {"saskia", "19"};
String[] data3 = {"erland", "19"};
DataResult[] result = database.executeStatement("delete from users where name='?' and age=?",data, data2, data3);

This will return the error state of the query.

I know, the implementation sucks big time, but it may work.

may, should... all in live is relative (?)

For Eli2:

String... === String[]

And

String[]... === String[][]

Wait, you haven't seen the new Thread() yet!

Ah ok
I have never seen this syntax, and never needed to use it.
Although it seems to be really common.

A lot of people like it, and I use it from time to time...

Another improvement in Java 1.5 were the for-each loops. REALLY useful when you just want to iterate a list, it saves a lot of typing (and you know that most of the bugs come from typos).

printf() is a variadic function, as is any function that takes a variable amount of arguments. It's really common

I don't know why, but I don't like printf.
