1. In this lab, you will read two files. Firstly, the ‘AccountData.csv’ file has the name and account number. Use each account number to scan the ‘BankData.csv’ file for a matching account number to get a ‘balance’ from the account transactions. You must repeatedly open, read the ‘BankData.csv’ file and close it for each account number in the ‘AccountData.csv’ file unless you wish to store its entire contents in a static array. (More code and may not be enough time to complete.) 2. So, for this lab, read my pseudocode in the given java files FIRST!! 3. ANALYZE my code carefully. 4. Then start coding the solution. I have given the solution to each lab instructor to help you during the time for your specific lab. 5. You will submit in iCollege, ONLY one file: BankDataProcessing.java 6. No need to submit the data files or the BankAccount ‘object’ file. 7. Do NOT MODIFY the ‘BankAccount.java’ file.
