PATH is an environment variable that is used by Operating System to locate the exe files (.exe) or java binaries ( java or javac command). The path once it is set, cannot be overridden. The PATH variable prevents us from having to write out the entire path to a program on the Command Line Interface every time we run it. Moreover, the path is just a variable that stores a bunch of shortcuts.

To execute Java console-based programs in Windows or Linux environments, we have to use Java and javac commands. The commands java and javac are not known to the operating system as we don’t specify where the executables reside. Hence, we need to specify the path where the executables are located. This is the reason we set the path and specify the path of the bin folder because the bin contains all binary executable files. After setting the path, it can load all necessary items in the program including the compiler or interpreter itself. 

Below is the procedure for how to set Java Path in both Windows and Linux?

Setting the Java path in Windows 10 is a simple process that ensures your computer recognizes and can execute Java programs. By following the steps outlined in this article, you can easily set the Java path and start developing Java applications.

Remember to download and install the latest version of Java from the official website. Then, modify the system environment variables by adding the Java path. This will allow you to run Java programs from anywhere on your computer.

In this article, you will understand the details about JAVA_HOME environment variable and how to set it on Windows 10. 

What is JAVA_HOME?

By convention, JAVA_HOME is the name of an environment variable on the operating system that points to the installation directory of JDK (Java Development Kit) or JRE (Java Runtime Environment) – thus the name Java Home. For example:

JAVA_HOME = c:\Program Files\Java\jdk1.8.0_201

Why is JAVA_HOME needed?

To develop Java applications, you need to update the PATH environment variable of the operating system so development tools like Eclipse, NetBeans, Tomcat… can be executed because these programs need JDK/JRE to function. So the PATH environment variable should include JAVA_HOME:

PATH = Other Paths + JAVA_HOME

Other paths are set by various programs installed in the operating system. If the PATH environment variable doesn’t contain a path to JRE/JDK, a Java-based program might not be able to run. For example, typing java in the command prompt showing this error:

'java' is not recognized as an internal or external command, operable program or batch file.

Or Eclipse will fail to launch:

How to set JAVA_HOME on Windows 10

Here are the visual steps to properly set value for the JAVA_HOME and update the PATH environment variables in order to setup Java development environment on your computer:

1. Firstly, you need to identify the Java home directory, which is typically under C:\Program Files\Java directory. Open My Computer and navigate to this directory, you will see:

Картинка с сайта: www.codejava.net

Here, the home of JDK is under C:\Program Files\Java\jdk1.80_201. The version number may vary, depending on the JDK you installed.

2. Open the System Environment Variables dialog by typing environment in the search area on Start menu. Click the suggested item Edit the system environment variables:

The System Properties dialog appears, click the button Environment Variables.

Картинка с сайта: www.codejava.net

Click OK, and you will see the JAVA_HOME variable is added to the list.

4.Update the PATH system variable. In the Environment Variables dialog, select the Path variable and click Edit:

Картинка с сайта: www.codejava.net

Then in the Edit environment variable dialog, double click on the empty row just below the last text line, and enter %JAVA_HOME%\bin as follows:

Картинка с сайта: www.codejava.net

The percent signs tell Windows that it refers to a variable – JAVA_HOME, and the \bin specifies the location of java.exe and javac.exe programs which are used to run and compile Java programs, as well as other tools in the JDK.

Click OK button to close all the dialogs, and you’re all set. Now you can open Eclipse or NetBeans to verify. Or open a command prompt and type in javac –version, you should see:

NOTES:

You can add the path to the bin directory of Java home directly into the PATH variable. But it’s strongly recommend to follow the above steps to setup a JAVA_HOME variable because many Java programs depend on it.

When you installed a JDK, you might not need to update the system variable because the installer already did it for you.
