Adding a directory to the Java PATH

Paths

To add a directory to the Java PATH, follow these steps:

Locate the Java installation directory: The first step is to locate the directory where Java is installed on your system. This directory contains the bin folder, which contains the Java executables like java, javac, and jar.
Copy the Java installation directory path: Once you have located the Java installation directory, copy the full path of the directory (e.g., C:\Program Files\Java\jdk1.8.0_231). Make sure to include the full path, including the bin folder.
Set the Java PATH environment variable: Next, you need to set the Java PATH environment variable. This variable tells the operating system where to look for Java executables when you run them from the command line.
- On Windows, you can set the environment variable using the following steps:
  - Press Win + X and choose System.
  - In the System window, click on Advanced system settings.
  - Click on the Environment Variables button.
  - In the System Variables section, scroll down to find the Path variable and click on Edit.
  - Add a new entry at the end of the list, using a semicolon (;) as a separator, and paste the Java installation directory path.
  - Click OK to save the changes.
- On MacOS and Linux, you can set the environment variable by editing the ~/.bashrc or ~/.bash_profile file:
  - Open a terminal window.
  - Type nano ~/.bashrc or nano ~/.bash_profile and press Enter.
  - Add the following line at the end of the file:
    export PATH=/path/to/java/bin:$PATH
  - Replace /path/to/java with the actual Java installation directory path.
  - Press Ctrl + X, then Y, and then Enter to save and exit.
Verify the Java PATH: To verify that the Java PATH has been set correctly, open a new command prompt or terminal window and type java -version. If Java is correctly configured, you should see the version information for Java.

By adding a directory to the Java PATH, you can ensure that Java executables are easily accessible from the command line, simplifying the execution of Java programs or use of Java tools.
