Macos – How To Install Java 17

Macos - How To Install Java 17
To successfully install Java 17 on Macos, start by downloading the appropriate .dmg file from the official Oracle website; then proceed to open this installer package and faithfully follow the included instructions, hence ensuring an optimized system environment for effective Java development.

Steps Description
Download Java 17 Visit Oracle’s official website and find the download link for Java SE Development Kit 17. Choose the macOS x64 Compressed Archive.
Installation Preparation Once the download is complete, a .tar.gz file will be available. Extract this file to reveal a directory named jdk-17.jdk which contains all the necessary installation files.
Moving Files Open Terminal and navigate to the location of the extracted folder. Utilise the ‘mv’ command to move this directory to /Library/Java/JavaVirtualMachines/. This is usually where all JDKs are stored in MacOS.
Setting JAVA_HOME Use Nano or Vim to open your shell profile (like ~/.bashrc or ~/.zshrc). Add the line:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-17.jdk/Contents/Home

. Save and exit the editor.

Verifying Installation In the terminal, run

java -version

to verify successful installation. If installed correctly, it should return:

‘java version “17.0.1”‘

We begin with downloading Java 17 from Oracle’s official site. It’s vital to ensure the macOS x64 Compressed Archive is chosen for this step to align with the MacOS setting.

Following a successful download, an archive (.tar.gz) file becomes available containing the necessary Java 17 installation files. This file needs to be extracted to advance further.

Next, using the MacOS terminal, we guide our path towards the folder where the extracted files reside. Following this, utilizing the ‘mv’ command helps us move this folder towards its designated spot: /Library/Java/JavaVirtualMachines/ which is coincidentally the common store place for all JDKs on MacOS.

The following action lies in setting the JAVA_HOME by opening the shell profiles found within the likes of ~/.bashrc or ~/.zshrc using either Nano or Vim tool. Addition of the following line in that profile is essential:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-17.jdk/Contents/Home

. Post entry, an act of saving before exiting is necessary.

Final verification steps includes running

java -version

to confirm a successful installation. If the process proceeds without hindrance, the terminal would rightly display ‘java version “17.0.1”‘.

Just as Jamie Zawinski aptly put: “Software Engineering might be science; but that’s not what I do. I’m a hacker, not an engineer”, your experience installing Java 17 on MacOS might well turn out to be a fun little hacker journey instead!
