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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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)) |
Using java, javac, jar, and CLASSPATH - a simple example
What Version of Java am I running? How do I edit, compile and run a Java program? What does this error message mean? How do I puts lots of classes into a single file, then run them from that file? How do I see what's in that file? How do I get Java to look for a class it needs in a series of places?
All good questions asked early on a Java course. And I answered them all earlier today. I have annotated the log [here], and you'll find the source code of my sample classes too - Annie, Bella, Chloe and Debbie.
From a Java Bootcamp Course, but taught on some other courses too! (written 2010-07-07)
