Week 12: Nov 12

Exam is wednesday

1. Autoboxing:
We briefly encountered this in the past:

	ArrayList<int> numlist;		// fails!!
	
	ArrayList<Integer> numlist;
	numlist.add(3);			// ok: expect Integer, get int
	int z = numlist.get(0);		// ok: expect int; get Integer
	
This has nothing to do with arraylists. Automatic int <--> Integer conversion
works anywhere:

Integer Z;
int z;
Z = z+1
z = 2*Z;


===================================================

	overrides getShortDescription, getLongDescripton
	respond overrides GO, LIGHT, TAKE
	note the check of inventory in getXDescription
	constructor trick!
	Note how anything that's a Light can be lit!!

This time with detail about Light extends Item

Compare to Food extends Item;
fields: amount_left;
method: is_gone();

Only need to do this *if* we need to store some attribute.

Look at Torch.
