Java for Hydrologists 101

There are a few postings on Java in this blog. Since I want to teach it to my students, I am quietly starting to populate this page with presentations which, eventually, will constitute the core of an informal class (;-)) the Java for Hydrologsts 101.

The focus of the JfH-101 is not simply to gain Java knowledge from the scratch (or so), but to address those topics and issues that have to do with my experience of hydrologist. So, I will try to cover Java as well as OMS3, and at the right time Geotools, and jgrasstools, not forgetting the tools of the tool (Ant, Maven, Git)^*, but in the meanwhile I will try to address the topics related to object oriented programming.  Programming is actually very much not talking about  that but doing it, so many of the slides will actually recall to actions.

3 -  A few diversions

• Short Intro to UML*  class diagram (YouTube 2018)
• UML - stands fro Universal Modelling Language. It is a set of graphic tools that can be used to sketch OO programs. The classical reference is Martin Fowler's, UML 2.0 distilled, 2003. It is a short and nice and time-affordable reading.

• Writing data to a File (no frills, no much design) (YouTube Live Video)
• Reading and writing data to a File. Designing the classes (YouTube Live Video)
• Reading and writing data to a File with Java 8. (YouTube Live Video) 
• For getting more on Streams see the chapter 3 of Modern Java in Action (a book worth to buy).

• Learning a little better what is a regular expression
•  Reading and writing data to a File with Java 8 II and III (YouTube video)

6 - Working with Git

• From command line
