ArrayList issues adding integers

Hi there,

I'm trying to create an arraylist of arraylists as a data structure to represent demographic data.

I've hit a brick wall already, when I try to add integers to one of my arraylists I get errors.

I'm using Eclipse and this program is for JavaSE 1.6

here's the code...

Eclipse tells me that there is:
Multiple markers at this line
- Syntax error on token(s), misplaced construct(s)
- Syntax error on token "id1", VariableDeclaratorId expected after this

at the lines that start caseid.add

Any help greatly appreciated!

Hi Michael. Welcome to The Ranch!

Your main problem there is that you're trying to add instructions directly to a class, rather than them being in a method. The declarations would work (but probably aren't what you intended - there's no reason for id1-id5 to be member variables). But the add lines have to be in a method (or at least an initialisation block).

Doh! Silly mistake, thanks Matthew!

It is sorta covered in the JavaRanch Style Guide.
