hi guys i really need plentiful help here. i am on my way developing a test case generator that will generate test cases for black box testing and white box testing. i've attached the program here. here's my problem:

1. i'm supposed to 'store' identifiers such as if..else and do...while. the problem is, i don't know how to store it and using what types of class. my lecturer said that i should use class list but i'm confused and as the result i got stuck on this part and the project is in dangerous level.

can someone help me out with this matter? just one example of how to store it and then accessing it is good enough for me. i am really desperate here. hope you guys can help me out. thanks in advanced
