In Unix terminology, an environment variable is a string containing information such as drive name, path, filename, etc. JAVA_HOME is an environment variable that points to the directory where Java Runtime Environment or Java Development Kit is installed in the system. To be specific, say if you have Java installed in the path C:\Program Files\Java\jdk1.8.0_121 on your computer, then your Java_Home is C:\Program Files\Java\jdk1.8.0_121. Basically, JAVA_Home is just an example used by Java-based programs like Apache Tomcat and other application server tools to find where Java is placed in the system.

These third-party programs use environment variables that point to the JDK or JRE directory. In simple words, it is easy for the programs to locate the executable directory like javac in the computer. If you are not using these third-party programs, it may not be mandatory for users to configure JAVA_Home in your system. In this article, we will explain in detail how to set JAVA_HOME as an environment variable in Windows 10.
