Java applet Introduction: Applet can be translated into small applications. Java Applet is such a small application written in Java language. They can be directly embedded into webpages, and can produce special results. A webpage containing an Applet is called a Java-powered page, which can be called a webpage supported by Java. When a user accesses such a webpage, the Applet is downloaded to the user's computer for execution, provided that the user is using a Web browser that supports Java. Since the Applet is executed on the user's computer, its execution speed is not limited by the network bandwidth or Modem access speed. Users can better enjoy the multimedia effects of Web-based applets. In Java Applet, You can implement graphics rendering, font and color control, animation and sound insertion, human-computer interaction, network communication, and other functions. The Applet also provides a Window development tool named Abstract Window Toolkit (AWT. AWT uses the GUI elements of the user's computer to create standard graphical user interfaces, such as Windows, buttons, and scroll bars. Currently, there are a lot of Applet examples on the network to vividly present these functions. Readers can access the corresponding web pages to view their effects. <BR> How Applet works. the HTML file code of a webpage containing an Applet contains a pair of tags such as <applet> and </applet>. When a web browser supporting Java encounters this pair of tags, the corresponding small application code will be downloaded and the Applet will be executed on the local computer.
