For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Fresh Paint - Java Arrays

I've just applied a coat of fresh paint to some of our Java examples - Arrays in Java - and added the refurbished examples on the web site. The great news is that the old code just worked (I love compatability) but I have much improved the comments.

1. [code] - a 2 dimensional array (or strictly speaking an array of arrays!)

2. [here] - a second example, where the array is not rectangular.

3. [here] - a dynamic example, where the various sizes are selected through user input (I have reused my WellHouseInput class to read from the user).




Other array handling examples ...

[here] - simplest array example in Java.

[here] - array initialisation in Java.

I've also extended my array first principles example to add in an array of strings and to do some good text handling - [here].

Illustration - from the training notes of our Java Courses; this illustrates the array structures set up in the examples that this blog refers to. Delegates on our course, which can be run at our training centre in Melksham, or on site, get a folder of notes that covers the course - around 60 to 80 pages per day.
