Further Java

Principal lecturers: Dr Alastair Beresford, Dr Andrew Rice
Taken by: Part IB
Past exam questions
Note: Questions from the old Concurrent Systems & Applications course are often relevant, although some knowledge of what is now the Concurrent & Distributed Systems course may required to answer parts of these questions. This year, questions for the Further Java course will not rely on knowledge of the Concurrent and Distributed Systems course in this way. With this caveat, suitable questions from the Concurrent Systems and Applications course include: 2002P5Q4, 2003P5Q4, 2004P4Q8, 2005P5Q4, 2006P5Q4, 2009P5Q6.

Tick List

Students must pass five "ticklets" (1-5 inclusive) in order to gain the overall tick for this course. Work completed for Tick 0 is marked separately and is also worth a tick.

Practical classes

Students are expected to attend one practical session per week. The dates and times of the practical sessions associated with this course are as follows:

Monday 2nd November2pm — 4pmA & B
4pm — 6pmC & D
Monday 9th November2pm — 4pmA & B
4pm — 6pmC & D

Monday 23rd November2pm — 4pmA & B
4pm — 6pmC & D
Monday 30th November2pm — 4pmA & B
4pm — 6pmC & D



The workbook for each practical class will appear here just prior to the start of the practical session.

Workbook errata

The printed workbooks contain (at the very least!) the following errors. Errors are indexed by workbook (W), page (P) and line (L), which may be negative, indicating that the reader should count upwards from the bottom of the page. These errors have been corrected in the on-line versions of the workbooks shown above. If you find any further errors, please email ticks1b-admin[at]

There is an error in the use of database connections and calls to commit in Workbook 5. Since the class Database only creates a single connection to the database, and calls to commit are made on this single connection, different threads may still interleave updates to the statistics table and the messages table. One easy fix is to create a new instance of Database for each instance of ClientHandler, however this might lead to performance problems when a large number of clients are connected. A better solution would associate a database connection with each instance of ClientHandler. You do not need to implement either fix to pass Ticklet 5 this year.
