A Windows' filename consists of two parts: filename and file type (or file extension) separated by a dot, e.g., Hello.java, Hello.class, Test.txt, etc. Windows can associate a program to each file type. For example, double-clicking a .txt invokes NotePad; double-clicking .jpg invokes Photo or Paint. This is a legacy from the old DOS'es day of 8.3 (name.type) filename syntax.
