What is a j file?

A J file is a source code file written in the Java programming language. Java was originally developed by Sun, and is a very popular programming language for developing both web applications and software programs. J files also frequently use the .JAVA file extension. J files may contain source code for an entirely complete program, or may contain smaller bits of code used by complete programs. J files are supported across the Mac, Windows, and Linux operating systems, and can be accessed and edited by a variety of Java readers and Java-based developer tools.  Other examples of source code files are C, FOR and H.
