Java is, and always has been, the source of many security holes. Here’s how you can install JRE (Java Runtime Environment). Open Safari and go to the Oracle Java downloads page and download the JRE.tar.gz version. You should end up with a file named something similar to jre-8u65-macosx-x64.tar.gz.
Checking to see if Java is installed
For everyone:
- •Open a terminal window (or a command prompt window if you are using Windows--NOT Cygwin)
- •Type 'java -version' and press enter. Then, type 'javac -version' and press enter.
- •For each of these you should see some text, and then the numbers '1.6.0_##'. (It doesn't really matter what's after the “_”, as long as the first part says 1.6.0). If you do, then you're all set for class.
- •If you see numbers other than 1.6, or get an error message, follow the steps below to install Java on your computer.
