In this article we will learn about the pre-defined Applet class which is available in java.lang package and the methods available in it.

 

The Applet class provides the support for creation and execution of applets. It allows us to start and stop the execution of an applet. Applet class extends the Panel class which extends Container class and which in turn extends the Component class. So applet supports all window-based activities.

 

Methods in Applet Class

Below are some of the methods available in the class Applet:

  • init() – This method is called when the execution of the applet begins. It is the entry point for all applets.
  • start() – This method is automatically executed after the init() method completes its execution or whenever the execution of an applet is resumed.
  • stop() – This method executes whenever the execution of the applet is suspended.
  • destroy() – This method is called when the webpage containing the applet is closed.
  • getCodeBase() – Returns the URL associated with the applet.
  • getDocumentBase() – Returns the URL of the HTML document that invokes the applet.
  • getParameter(String paramName) – Returns the value associated with the paramName. Returns null if there is no value.
  • isActive() – Returns true if the applet is started or false if the applet is stopped.
  • resize(int width, int height) – Resizes the applet based on the given width and height.
  • showStatus(String str) – Displays the string str in the status bar of the browser or applet.
