My name is Jeff Friesen and I teach various technologies. Because I mostly teach Java, I was nicknamed JavaJeff back in the 1990s. I teach Java by writing articles and books, and by creating other resources. My goal is to help people master this technology and improve their job prospects.
In the 1980s I studied Fortran at high school, and later attended Brandon University where I obtained a Bachelor of Science degree with majors in computer science and mathematics. I studied Pascal, VAX assembly language, data structures and algorithms, computer graphics, Cobol, computer networks, digital image processing, APL, databases, systems programming, compiler construction, and numerical analysis. I also studied calculus, analysis, linear algebra, statistics, and set theory and algebra. I graduated in 1987 and received the following diploma:
After graduating, I worked at a telecom company (where I created software to automate computer tasks and track employee absences, among other activities), an investment firm (where I created software to manage a client's portfolio of investments, and accomplished other tasks), and two software development firms. I taught myself C/C++, Visual Basic, Windows APIs and architecture, HTML, XML, UML, and Java (and more).
At some point, I began to freelance as a tech teacher, focusing mainly on the Java language, Java APIs, and other Java topics through the articles and books I continue to write for InfoWorld, Apress, and other companies. I've also taught Java to students in college and university environments.
