Here is the link to exam 2 of the Fall 2001 semester. This semester's exam 2 will have a similar format and similar type of questions. Use the lab time to work on the old exam as a way to prepare for the upcoming exam. Feel free to discuss the problems with your lab mates. The labbies are there to help you too.
Exam 2 will cover materials from week 05 to week 10 inclusive. Be sure to know the syntax of anonymous classes and how to use them. Lab 07 of Fall 2001 has a few good exercises on anonymous classes. Take a look!
You probably will recognize a few questions similar to the ones we did in the lectures. You should try to do them without looking at the lecture notes.
Relax, enjoy the learning, and don't forget to have fun!
