How to Setup Java on Mac

Here are the steps to set up Java on a Mac operating system:

1. Download the latest version of Java from the Oracle website (https://www.oracle.com/java/technologies/javase-downloads.html).
2. Run the downloaded installer package and follow the instructions to install Java on your computer.
3. Once the installation is complete, open the terminal and type "java -version" to verify that Java has been installed properly.
4. Next, set the JAVA_HOME environment variable to the location of the installed Java. You can do this by: a. Open the terminal and type: sudo nano /etc/bashrc b. Add the following line to the file: export JAVA_HOME=$(/usr/libexec/java_home) c. Save the file (Ctrl+O) and exit (Ctrl+X) Finally, add the Java bin folder to your system's PATH environment variable by: a. Open the terminal and type: sudo nano /etc/bashrc b. Add the following line to the file: export PATH=$JAVA_HOME/bin:$PATH c. Save the file (Ctrl+O) and exit (Ctrl+X) Verify the setup by opening a terminal and typing "javac" (without quotes). This should display the options for the Java compiler. You should now be able to run Java programs on your Mac computer.
