1. Standalone applications: A standalone application is a program that runs on your computer. It is more or less like a C or C++ program.
2. Applets: An applet is a application designed to travel over the internet and to be executed on the client machine by Java compatible web browser like Firefox or google chrome. Applets are also java programs but they reside on the servers. An applet can not be executed like standalone application. Applet can be executed only by embedding it into an HTML page like an image or sound file. To run an applet you need to access an HTML page which has applet embedded into it. When the web browser downloads such an HTML page, It subsequently loads the executable file, which contains Applet and then executes it on the local machine.
3. Web Applications: Web applications run on the web server. Web applications are accessed through web clients i.e. web browsers like firefox and google chrome. Whenever you access some web site by specifying the url, you are accessing some web application written in java.
