Installing Java on macOS

To install Java on macOS, follow these steps:

Step 1: Download the JDK

Go to the Oracle JDK download page, choose the latest JDK version, and download the appropriate .dmg installer.

Step 2: Install the JDK

Open the .dmg file you downloaded and follow the prompts to install the JDK. You may need to enter your administrator password during the installation process.

Step 3: Set Environment Variables

Once the installation is complete, you need to configure environment variables so your system knows where Java is installed. Open the Terminal and type:

nano ~/.bash_profile

This command opens the .bash_profile in a text editor. Add the following lines to set the JAVA_HOME variable:

export JAVA_HOME=$(/usr/libexec/java_home)
export PATH=$JAVA_HOME/bin:$PATH

Press Ctrl + X to exit, Y to save the changes, and Enter to confirm. Close and reopen the Terminal to apply the new settings.

Step 4: Verify the Installation

To confirm Java is installed correctly, check its version with the following command:

java -version

If you encounter an error, it indicates the installation wasn’t successful.
