Installing Latest JDK on macOS
This section provides a tutorial example on how to download and install the latest version JDK, which includes some nice Java tools, on a macOS system.
As a Java developer kit, the Oracle JDK package includes a number of nice Java tools.
Here is what I did to download and install JDK 15, also called Java SE 15, on my macOS computer.
1. Go to Oracle Java SE download website at oracle.com/technetwork/java/javase/downloads/index.html.
2. Click "JDK Download" next to "Java Platform (JDK) 15".
3. Click "jdk-15_osx-x64_bin.dmg" from the download list. It will be saved to your "Downloads" directory automatically.
4. Double click on "jdk-15_osx-x64_bin.dmg" to install it.
To 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 "15" 2020-09-15 Java(TM) SE Runtime Environment (build 15+36-1562) Java HotSpot(TM) 64-Bit Server VM (build 15+36-1562, mixed mode, sharing)
Cool, I have successfully installed JDK 15 on my macOS computer!
