1.  Standalone Application:

Standalone applications are also known as desktop applications. These are also known as window-based applications. These are traditional or conventional softwares that we need to use on every machine. For Example standalone applications are: Media players, antivirus etc. AWT(Abstract Window Toolkit) and Swing are used for creating or building standalone applications in java.
