Prerequisites to Install Java in macOS

As a part of the system requirements, the system must have an intel-based microprocessor with macOS(10.x or later versions) as an operating system running over it. In addition, the system must have administrative privileges because JDK must be installed systemwide and not for the specific user group or a user profile. Lastly, the system needs a 64-bit web browser, such as Safari.

Evaluate the Current JDK Version in Java

If a user uses a command prompt to run the Java application, one should first check the default version of JDK using the command java -version. A system can have more than one Java installed over it.

After running the given command in the prompt, you’ll know that JDK is already installed if a specific version is displayed. However, if you encounter the command not found message, there’s no JDK that’s previously installed.

JDK Download Instructions Using the UI Interface

  • Download the JDK .dmg file for macOS.
  • Click the accept button for the license agreement.
  • From the download section, double-click on the .dmg file to start its execution.
  • A finder window appears that has an open box icon, and the .pkg package file name comes.
  • Double-click on the .pkg file to start the installation.
  • Initially, a pop-up window appears.
  • Click the continue button.
  • The type dialog box appears.
  • Click the install button.
  • The progress bar now appears over the dialog box with a message over it to enter the system credentials.
  • Enter the username and password and click the install button to install the application.
  • Once successful installation takes place, delete the .dmg file to save disk space.

JDK Download Instructions Using the Command Prompt

  • Open the command prompt.
  • Run the command to install the JDK from the Homebrew package manager, brew tap adoptopenjdk/openjdk.
  • To install Java 8, run the command, brew cask install adoptopenjdk8, to install the version.
  • Once the JDK gets successfully downloaded, open the .bash_profile file.
  • Use the nano ~/.bash_profile command to open the file.
  • Add the Java home path to the file using the command, export JAVA_HOME=/usr/libexec/java_home -v1.8.
  • Press Ctrl+X to exit the file.
  • Reload the .bash_profile to take effect.
  • Check the Java version from the command prompt using java -version OR $JAVA_HOME.
