File Extension CLASS

File type: Java Bytecode file

About the CLASS file type:

If Windows cannot find the appropriate program associated with .CLASS files, then your registry may have errors. Check your Windows registry for errors (includes file association errors).

The .CLASS file extension is associated with Sun Microsystem's Java programming language bytecode files. When a Java compiler compiles a source code file (which will end with the file extension .JAVA) it will store the output in a .CLASS file which can then be loaded using a Java Virtual Machine.

Additional Information:
To open, or execute, a .CLASS file you will need to install a Java Virtual Machine.
