Convert CLASS to JAR

What is CLASS file?

The CLASS file extension is used by Java software to represent compiled Java programs. A .CLASS file contains machine code called bytecode, which can be read and executed by Java Virtual Machine (JVM), an interpreter for code written in Java language. This bytecode of compiled program have stable format, and that makes it possible to launch compiled programs on any machine and operating system that has a suitable Java virtual machine installed.

What is JAR file?

The JAR (Java Archive) file extension is associated with the Java Runtime Environment (JRE). It is a platform independent file format used to combine multiple class files and associated metadata time into one file for distribution. JAR files are not dependent on any specific hardware or operating system, and can be used in any Java environment. It works like a ZIP file, by compressing more than one files into a single unit for easier management and storage. [ ⏩ ] JAR file extension

How to convert the file from CLASS to JAR?

To successfully convert the CLASS file to JAR, you should install one of the applications from the list. After installing the software, open the program and select the file you want to convert (file-name.CLASS). The next step is to select the target format from the list, in this case JAR (usually converters allow you to convert to several different formats, so check out their features - maybe one of the available formats will suit you more than JAR).

What is a file conversion?

A data conversion is normally an automated process to some extent. The effect of the operation of one program is automatically the input product of another application. If that does not happen we need to help the process a little bit and convert the file on our own, e.g. CLASS to JAR. To obtain a matched structure of the data, it is necessary to use an appropriate converter.

Program for converting CLASS files to JAR files is a kind of a "binary code translator" compensating for the differences in the code or translating it in such a way so that another application could use it. For us, as users, the visible change will be only another file extension. (After converting the file, it will be the extension JAR, while before this step we had the CLASS file). For the programs, the difference is on a much higher level – either the application will be able to open a new JAR file, or not.
