To learn Java, you need to have a copy of JDK (Java Development Kit) installed on your machine. If you are a Mac computer user, you can follow this tutorial to download and install JDK 13 on your Mac computer.
1. Go to Oracle Java SE download website at oracle.com/technetwork/java/javase/downloads/index.html.
2. Click "Download" next to "Java Platform (JDK) 13".
3. Click "jdk-13_osx-x64.bin.tar.gz" from the download list. It will be saved to your "Downloads" directory automatically.
4. Start a Terminal window and run commands below to install it.
herong$ cd ~/Downloads herong$ gunzip jdk-13_osx-x64.bin.tar.gz herong$ tar -xf jdk-13_osx-64.bin.tar herong$ sudo mv jdk-13.jdk/ /Library/Java/JavaVirtualMachines/
5. Test the installation, open a command window to try the java command. If you are getting the following output, your installation was ok:
herong$ java -version java version "13" 2019-09-17 Java(TM) SE Runtime Environment (build 13+33) Java HotSpot(TM) 64-Bit Server VM (build 13+33, mixed mode, sharing) herong$ javac -version javac 13
