Log in to Laulima, go to the site for this course, click on Weekly Engagement and complete the Week 1 - Participation Verification “assignment.”
Most programming assignments in this course are in Java, and so can be done on any OS. Assignments that require other programming languages (C/C++, Python) will be done via a Linux Docker container that is invoked from Java! Provided that Docker runs on your machine, you should be good for this course regardless of your OS.
Your system must support Java 21, so any JDK 21 will work (it’s the LTS). If you don’t know which version you have, if any, in a terminal just type java --version
. The first line of output will look like openjdk version "X.0.1"
. If X
is 21 or higher, you’re all set and you can proceed to Section 2.2 below. If not, or if you get some command not found
message, you have to install a more recent JDK.
There is plenty of information on how to do this on-line, with OpenJDK or Oracle’s JDK
Once you’re done, doing java --version
should behave as expected.
Maven is a build tool for Java, and we will use it extensively. It really
makes configuring/building Java projects a breathe. There are other
systems, some fancier (like Gradle), but in this course we’ll stick to
Maven. If you don’t know which version you have, if any, in a terminal
just type mvn --version
. The first line of output will look like Apache
Maven X.Y.Z
. If X.Y.Z
is 3.6.3 or higher, you’re all set and you can
proceed to Section 2.3 below. If not, or if you get some command not
found
message, then you have to install Maven:
On Ubuntu: sudo apt install maven
(on a recent Ubuntu this should install a version that’s 3.6.3 or above)
On MacOS: If you use MacPorts or HomeBrew to install software on your Mac, then just use one of those as you would for any other software install. If not, you can start using one of these two. Alternatively, you can always install Maven from source.
On Windows: you can simply download the Binary zip archive from the Maven download page
Make sure Docker is installed and runs on your system.
Make sure you have an IDE installed for developing Java code. I use the IntelliJ IDEA IDE, but if you already have your own IDE of predilection that’s fine of course.
