    Direct Known Subclasses:
    JApplet

    An applet is a small program that is intended not to be run on its own, but rather to be embedded inside another application.

    The Applet class must be the superclass of any applet that is to be embedded in a Web page or viewed by the Java Applet Viewer. The Applet class provides a standard interface between applets and their environment.

      • Applet

        Constructs a new Applet.

        Note: Many methods in java.applet.Applet may be invoked by the applet only after the applet is fully constructed; applet should avoid calling methods in java.applet.Applet in the constructor.

        Throws:
        HeadlessException - if GraphicsEnvironment.isHeadless() returns true.
        Since:
        1.4
        See Also:

    • Method Detail

      • setStub

        Sets this applet's stub. This is done automatically by the system.

        If there is a security manager, its checkPermission method is called with the AWTPermission('setAppletStub') permission if a stub has already been set.

        Parameters:
        stub - the new stub.
        Throws:
        SecurityException - if the caller cannot set the stub
      • isActive

        Determines if this applet is active. An applet is marked active just before its start method is called. It becomes inactive just before its stop method is called.
        Returns:

      • getParameter

        Returns the value of the named parameter in the HTML tag. For example, if this applet is specified as

        then a call to getParameter('Color') returns the value 'blue'.

        The name argument is case insensitive.

        Parameters:
        name - a parameter name.
        Returns:
        the value of the named parameter, or null if not set.
      • getAppletContext

        Determines this applet's context, which allows the applet to query and affect the environment in which it runs.

        This environment of an applet represents the document that contains the applet.

        Returns:
        the applet's context.
      • resize

        Overrides:

        Parameters:
        d - an object giving the new width and height.
      • isValidateRoot

        Indicates if this container is a validate root.

        Asus rt n12+ reset. Applet objects are the validate roots, and, therefore, they override this method to return true.

        Overrides:
        isValidateRoot in class Container
        Returns:
        true
        Since:

        Parameters:
        msg - a string to display in the status window.
      • getImage

        Returns an Image object that can then be painted on the screen. The url that is passed as an argument must specify an absolute URL.

        This method always returns immediately, whether or not the image exists. When this applet attempts to draw the image on the screen, the data will be loaded. The graphics primitives that draw the image will incrementally paint on the screen.

        Parameters:
        url - an absolute URL giving the location of the image.
        Returns:

        name - the location of the audio clip, relative to the url argument.
        Returns:
        the audio clip at the specified URL.
        See Also:
        AudioClip
      • getAppletInfo

        Returns information about this applet. An applet should override this method to return a String containing information about the author, version, and copyright of the applet.

        The implementation of this method provided by the Applet class returns null.

        Returns:
        a string containing information about the author, version, and copyright of the applet.
      • getLocale

        Gets the locale of the applet. It allows the applet to maintain its own locale separated from the locale of the browser or appletviewer.
        Overrides:
        getLocale in class Component
        Returns:
        the locale of the applet; if no locale has been set, the default locale is returned.
        Since:
        JDK1.1
        See Also:
        Component.setLocale(java.util.Locale)
      • getParameterInfo

        Returns information about the parameters that are understood by this applet. An applet should override this method to return an array of Strings describing these parameters.

        Each element of the array should be a set of three Strings containing the name, the type, and a description. For example:

        The implementation of this method provided by the Applet class returns null.

        Returns:
        an array describing the parameters this applet looks for.
      • play

        Plays the audio clip at the specified absolute URL. Nothing happens if the audio clip cannot be found.
        Parameters:
        url - an absolute URL giving the location of the audio clip.
      • play

        Plays the audio clip given the URL and a specifier that is relative to it. Nothing happens if the audio clip cannot be found.
        Parameters:
        url - an absolute URL giving the base location of the audio clip.
        name - the location of the audio clip, relative to the url argument.
      • init

        Called by the browser or applet viewer to inform this applet that it has been loaded into the system. It is always called before the first time that the start method is called.

        A subclass of Applet should override this method if it has initialization to perform. For example, an applet with threads would use the init method to create the threads and the destroy method to kill them.

        The implementation of this method provided by the Applet class does nothing.

        See Also:
        destroy(), start(), stop()
      • start

        Called by the browser or applet viewer to inform this applet that it should start its execution. It is called after the init method and each time the applet is revisited in a Web page.

        A subclass of Applet should override this method if it has any operation that it wants to perform each time the Web page containing it is visited. For example, an applet with animation might want to use the start method to resume animation, and the stop method to suspend the animation.

        Note: some methods, such as getLocationOnScreen, can only provide meaningful results if the applet is showing. Because isShowing returns false when the applet's start is first called, methods requiring isShowing to return true should be called from a ComponentListener.

        The implementation of this method provided by the Applet class does nothing.

        See Also:
        destroy(), init(), stop(), Component.isShowing(), ComponentListener.componentShown(java.awt.event.ComponentEvent)
      • stop

        Called by the browser or applet viewer to inform this applet that it should stop its execution. It is called when the Web page that contains this applet has been replaced by another page, and also just before the applet is to be destroyed.

        A subclass of Applet should override this method if it has any operation that it wants to perform each time the Web page containing it is no longer visible. For example, an applet with animation might want to use the start method to resume animation, and the stop method to suspend the animation.

        The implementation of this method provided by the Applet class does nothing.

        See Also:
        destroy(), init()
      • destroy

        Called by the browser or applet viewer to inform this applet that it is being reclaimed and that it should destroy any resources that it has allocated. The stop method will always be called before destroy.

        A subclass of Applet should override this method if it has any operation that it wants to perform before it is destroyed. For example, an applet with threads would use the init method to create the threads and the destroy method to kill them.

        The implementation of this method provided by the Applet class does nothing.

        See Also:
        init(), start(), stop()
      • getAccessibleContext

        Gets the AccessibleContext associated with this Applet. For applets, the AccessibleContext takes the form of an AccessibleApplet. A new AccessibleApplet instance is created if necessary.
        Specified by:
        getAccessibleContext in interface Accessible
        Overrides:
        getAccessibleContext in class Panel
        Returns:
        an AccessibleApplet that serves as the AccessibleContext of this Applet
