.jar File Extension

Developer: Oracle
File type: Java Archive File
You're here because you have a file that has a file extension ending in .jar. Files with the file extension .jar can only be launched by certain applications. It's possible that .jar files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .jar file?

A Java Archive file is also called a JAR file, and these Java Archive files are integrated with compilation specifications proprietary to Oracle. These Java Archive files are also implemented with encoding specifications also proprietary to Oracle for the JAR format. JRE (Java Runtime Environment) uses the data stored in these JAR files as reference data or an application library of a program developed using Java and intended to run in platforms where the Java Runtime Environment is enabled. The content of a JAR file may include framework code developed to initialize and run Java programs. These JAR files can also be created as standalone applications for mobile phones, tablet computers and desktop or laptop computers installed with the Java Runtime Environment. Program resources may also be included in the content of a JAR file, and a manifest file can optionally be entered in a JAR file. Some Web browsers are integrated with support for the Java Runtime Environment and can thereby be used to access the data stored in these JAR files. The Java Virtual Machine is also known as the Java Runtime Environment. Sun Microsystems was the original developer of the JAR format before it was acquired by Oracle.

how to open a .jar file?

Launch a .jar file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .jar file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .jar files aren't yet associated with it. In this case, when you try to open a .jar file, you can tell Windows which application is the correct one for that file. From then on, opening a  .jar file will open the correct application.

The Java Runtime Environment was developed by Oracle and this is a very useful application today as most of the programs offline and online use Java technology. This application is used on most operating systems to allow users to run applications that require Java whether they are Java plug-ins or Java Web start. This application belongs to the Java Development Kit, wherein it is known as a set of tools that is used for Java application development. The Java Runtime Environment also features a Java virtual machine and this is the feature that enables Java applications to run on a certain operating system. This virtual machine makes up an ideal environment for creating applications with Java. It contributes a lot to convenience for users when it comes to opening Java applications. This software is available in different languages as well as runs on Windows, Linux and MAC operating systems. Also, this is one of the applications used to open JAR files which stand for Java Archive Files.

a word of warning

Be careful not to rename the extension on .jar files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .jar. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
