/import/teaching/BSc/1st/ItP) can be found here, along with some other material described in the lecture summaries for the last year I taught the course.
The notes were produced to accompany lectures and textbooks, not to replace them, and in the final year I taught the course I concentrated particularly on building up a set of external links rather than extending or modifying the notes. So while they may be read in order as a tutorial in programming using Java with the emphasis I felt appropriate for the course, they are not a complete piece of work, nor are they my final thoughts on "how to program using Java".
A few of these notes were written by other members of staff who assisted me on this course, acknowledgement is given where this is the case.
