Downloadable resources

I know someone fairly new to Java who is interested in continuing their Java education. However, they will have no internet access while they're not at school this summer and they don't really have enough money to buy a good book. Are there any good resources online that he could download to use over the summer? Links to .pdf files or (downloadable) tutorials or whatever would be appreciated.

You could go to amazon.com or other sites and buy good used book for cheap. I've done it and highly recommend it. On average, the quality of the books was much higher than the descriptions suggested.

I didn't consider a used book.. He might have enough money for that. Thanks
