In this case, run the command in 3rd step to check whether javac is already installed. response, it means you already have Java. If you see java is not recognized as an internal or external command, operable program or batch file response like on the image below, it means Java isn't installed on your Windows 11. Type java -version command and hit Enter.

Instead, it contains class libraries and supporting files required for the purpose of execution of the program.In this tutorial, I'm going to show you how to install Java and configure its environment variables on Windows 11, including JAVA_HOME.Įven if you don't have any idea about how to complete these tasks, thanks to the clear explanations and screenshots for each step, you'll be able to install Java completely. On the other hand, JRE is not responsible for development purposes so it doesn’t contain such tools as the compiler, debugger, etc. Since JDK is responsible for the development purpose, therefore it contains tools which are required for development and debugging purpose.

It is mainly used for creating an environment for code execution. It is mainly used for the execution of code and its main functionality is development. JRE(Java Runtime Environment) is the implementation of JVM(Java Virtual Machine) and it is specially designed to execute Java programs. JDK also contains numerous development tools like compilers, debuggers, etc. JDK(Java Development Kit) is used to develop Java applications. Let’s see the main difference with the help of the below diagram: If we only want to execute a program, we just need to install JRE and not JDK, since there is no development or compilation of the code required. It doesn’t contain any development tools like a compiler, debugger, etc. It consists of JVM, Java binaries, and other classes for the smooth execution of the program. It is the implementation of JVM (Java Virtual Machine) and it is specially designed to provide an environment to execute Java programs. We can possibly install more than one JDK version on the same computer. It contains Java Runtime Environment(JRE) and other development tools like an interpreter, compiler, archiver, and a document generator. Java developers can use it on their Windows, macOS, Solaris, and Linux to code and run Java programs.
