Ask Question. Asked 11 years, 2 months ago. Active 6 years, 1 month ago. Viewed 8k times. It says: Note: Keep implementations of the destroy method as short as possible, because there is no guarantee that this method will be completely executed.
I'm a bit shocked that the above isn't in the javadoc. Improve this question. Matt McHenry. Add a comment. Active Oldest Votes. But as far as i learned it, the general rule is: init should get the applet ready to run, but not actually set it in motion. The applet should be in a "stopped" state upon return from init. A stopped applet should be using as few resources as practically possible, and no CPU.
It generally won't read params and reload images and all that, as that should be done in init. It should not undo any of init 's work, as that would leave the applet unstartable if the functionality is properly separated. It basically undoes init. It should not stop the applet; that's stop 's job, and should already be done before destroy is called. Improve this answer. Do not construct a frame window for the application. Your application will be displayed inside the browser. Move any initialization code from the frame window constructor to the init method of the applet.
You don't need to explicitly construct the applet object. The browser instantiates it for you and calls the init method. Remove the call to setSize; for applets, sizing is done with the width and height parameters in the HTML file. Remove the call to setDefaultCloseOperation. An applet cannot be closed; it terminates when the browser exits.
If the application calls setTitle, eliminate the call to the method. Applets cannot have title bars. You can, of course, title the web page itself, using the HTML title tag.
Applets inherit a group of event-handling methods from the Container class. The Container class defines several methods, such as processKeyEvent and processMouseEvent, for handling particular types of events, and then one catch-all method called processEvent. Initially, the applet will display "initializing the applet.
Starting the applet. To display an image within the applet, you use the drawImage method found in the java. Graphics class. An applet can play an audio file represented by the AudioClip interface in the java. The getAudioClip method returns immediately, whether or not the URL resolves to an actual audio file. The audio file is not downloaded until an attempt is made to play the audio clip. Java - Applet Basics Advertisements. Previous Page. Next Page. Previous Page Print Page.
