How to run a JAR file in Windows 10

JAR files are nothing but files similar to EXE files that need a Java framework for running. Just like how the exe files need Windows OS to run, the JAR files need Java framework.

When one opens a JAR file, they not just open it like an archive file but like an executing file. Just know that since JAR files do not open using Windows OS, we will need Java Framework on the PC.

Download and install Java Framework

To run JAR files, Windows users need Java installed on their PC. While installing Java, make sure that the files and the Java version are corresponding. In case you have an older version of Java installed on your PC, and if it causes any problem in installing the latest Java framework,  then you can remove the former by the Java Remover Tool.

After installation of Java, follow the below 3 steps-

Set System Path for Java

Now set the JAVA_HOME path. This will enable the JAVA file you run to find the essential libraries for the program.

One can also use the command line for echoing the Java path to check if it is correct.

Run a Java or JAR file

Double click on the JAR file and you will see that it automatically runs they way the EXE files execute. In case there is some issue with version, the file will certainly inform you.

In case there is a JAR file on your PC that is not running on its own, then you can utilize the java JDK so as to run it.

Then open the Command Prompt, and enter the command –  java -jar name_of_jar_file.jar. This will automatically execute the JAR file.

Set the Java or JAR file association

Lastly, establish a file association with  Java run time. This way every time you run the file, you are not asked to select a program that can execute it.
