I want to get this going as early as possible in case there are any problems. So please get on this ASAP so we have plenty of time to solve problems.
You will need to download and install two pieces of software: the Java compiler (known as the JDK), and a Java development environment (IDE: Integrated Development Environment) called jGRASP.
If you are on a school/district laptop, you will need to use the Software Center app:
If you are on a non-school/district computer, you will have to install this software yourself. Some of you may already have the JDK installed because of other software on your computer that is written in Java. If you think this applies to you, you may safely skip the JDK installation, although you may find that you need to come back and complete it anyway.
