A Java applet is a small software program written in the Java language, a programming language used primarily on the World Wide Web. A Java applet is a separate file referenced by an HTML (HTML: The standard markup language used for documents on the World Wide Web. HTML uses tags to indicate how Web browsers should display page elements such as text and graphics and how to respond to user actions.) document. A Java applet might be used to add animation, music, database operations, or Web page updates to a Web page. If you are a developer, you can edit Java applet code from Office.
When you open a Web page that contains a Java applet in an Office program, an icon representing the applet
appears on the page. The icon does not appear when you view the Web page in a browser or when you print your Web page.
Tip
Be careful when copying and moving Java applets. Although some Java applets are self-contained and work correctly in any location on any page, other Java applets are dependent on the structure of the Web page. When copied or moved to another Web page— or to another location within a Web page— these Java applets might not run correctly or might return errors when viewed in a browser.
