We need to install Java and add JAVA_HOME in the Operating System user environment variable to work with software like Maven, Jenkins, React Native, Gradle, Tomcat and develop mobile apps with SDK. The path is required to be set for using tools such as javac, java, etc. If you have Java file outside the JDK/bin folder, it is necessary to set the path of JDK.
If you keep the Java source file inside the JDK/bin directory, the path is not required to be set because all the tools will be available in the current directory.
