Java Training

Hello,

I am extending some tutoring on JSE 5 at my college. The audience is final year students pursuing bachelor's of Engineering.
I am using Thinking of Java as the reference book. All the PPTs that I am making are based on this book. In addition, I am planning to ask the students to buy a copy of Head First Java.

Do you think that this would help them in a good way?

I would also be grateful to anyone who can suggest some interesting games/activities to learn Core Java. This is going to be a 9 hour per day long training program for about 10-12 days. So I don't want it to be a drudgery. I want it to be interesting. I have come up with some activities but I don't think that they are really very good. Also, some of them seem to be like quite time consuming.
Any suggestions/comments are welcome!

What activities have you come up with? If you could briefly describe them, you may get some good suggestions to improve them.

Hello James,

I'm very naive in this field, but these are a couple of activities I've thought about

1) To explain the Is-a and Has-a relations, I've made cards with a picture on each card. Each card is part of a larger group. There are five such groups. Each student gets one card and he needs to find the group it belongs to. The group has a whole has to derive the relations that exist between all these objects and the first group that comes with the solution - gets a prize - mostly chocolates

example - There would be pictures of a Car, BMW, Wheel, and so on. Each student will have one of these. He has to find others with whom he'll have some relation (I'll be displaying the objects in a group on the Projector). They then have to find the relations
Car has a wheel (or BMW has a wheel)
BMW is a car and so on.

2) I've designed some small quizzes as well.

Since this is the first week, these are the only activities I've completely planned for. Need some more suggestions for the next week.

It's a class of 45 students and I'll also have help from 5 volunteers.
