java class file





























a java class file is a file (with the .class filename extension) containing java bytecode that can be executed on the java virtual machine (jvm). a java class file is usually produced by a java compiler from java programming language source files (.java files) containing java classes (alternatively, other jvm languages can also be used to create class files). if a source file has more than one class, each class is compiled into a separate class file.

filename extension





























a filename extension is an identifier specified as a suffix to the name of a computer file. the extension indicates a characteristic of the file contents or its intended use. a file extension is typically delimited from the filename with a full stop (period), but in some systems it is separated with spaces.





























some file systems implement filename extensions as a feature of the file system itself and may limit the length and format of the extension, while others treat filename extensions as part of the filename without special distinction.
