What Is a Jar File?
JAR stands for Java Archive. A JAR file contains image files, audio files, directories or class files in compressed versions. That means in a single JAR file, there can be a lot of other files. This seems that JAR files are similar to a ZIP file. Though they both look familiar, they both are different in their own way. They perform different functions. JAR files aggregate many Java class files and its meta data and resource files into a single file for distribution. JAR files are Java-specific manifest files and are built on the ZIP format.
ZIP files on the other hand are the compression files and have archiving features. JAR files essentially have a manifest which directs JAR on holding and containing the information. JAR files are designed to be specifically run under Java RuntIme Environment. The Java runtime Environment is a software that is designed to run other softwares including the JAR files.

How To Run Jar Files In Your Computer:
In this section, we will show how you can run the JAR files in your computer due to some reason. One technical reason for a JAR file not open on your PC is that you do not have Java Runtime Environment installed in your computer. You can run the JAR file using the Java Runtime Environment as well as can view the files contained in the JAR files by using any decompressing program. The procedure for both of your potential selection is given below.
Procedure 1: Running Jar Files
If you want to run the JAR file, the foremost thing you need to ensure is that Java Runtime Environment is installed in your computer. In case you do not have this program installed in your computer, you need to download the latest Java Runtime Environment from this link https://www.java.com/en/download/ . Once you are done with downloading and installing the Java Runtime Environment, double click on the JAR file to open it. In case the file does not open by double clicking on it, you need to right click on the JAR file and select “open with” and from the list of programs, select “Java Runtime Environment” and check “Always choose this app to open jar file” and select “ok”. This should always open the JAR files by the Java Runtime Environment as default by double clicking on any JAR file.
Procedure 2: Decompressing the Jar File
Decompressing the JAR file is as simple as opening a ZIP file. It is a non-executable process where you can only view the content of the JAR file. There are many software that can decompress the JAR file namely “WinRAR”, “7-ZIP”, “JarX”, and you can download any of these from the internet. Once you have a decompressing program in your computer, you can easily open the JAR by following the below stated steps.
Open WinRAR on your computer.
Click on the compressed Jar file to open with WinRAR. The JAR file will open as shown below.
Once the file is extracted, double click on the JAR file to make it open.
That is all; the JAR file will open revealing all the files it had bundled together in it.
If you have a JAR file and are unable to open it, you can also rename the file type as a “ZIP” file and use the WinRAR or any other extraction program to open the JAR file. This will work as well.
Opening a JAR file is not a big issue if you know the right chord to strike. Make sure you have the Java Runtime Environment Installed in your computer. Then you can easily run the JAR file. Alternatively, you can use any decompressing program to decompress the JAR file to view its contents. However, there are other issues with JAR files as well such as the JAR file will not open after you double click on it or due to other reasons. For that, there are procedures to solve this issue as well and make things work for you but that is saved for another article.
