This document provides information about applet programming in Java. It discusses that applets are small Java programs used primarily for internet computing. Applets can perform tasks like displaying graphics, playing sounds, and accepting user input. Key differences between applets and standalone applications include applets not having a main method, needing to be embedded in an HTML page, and having restrictions on file/network access. The document also covers the applet lifecycle, writing applet code, and using HTML tags to embed applets in web pages.
