The browser should provide an environment known as a container for the execution of the applet.

destroy() method Browser Responsibilities for Applet Life CycleĪpplet life cycle methods are callback methods because they are called implicitly by the browser for the smooth execution of the applet.

Following are the methods for a full applet cycle. Here, programmers write the above-mentioned methods with some code but never calls. These methods are named so because they are called automatically by the browser when required for smooth execution of the applet. All of these methods have a name and they are called as callback methods. In the life of execution, the applet exists (lives) in one of these 5 states. This cycle is known as Applet life cycle, where each state is signified by methods. Life Cycle of Java AppletsĪn applet undergoes various stages between its creation of objects and object removal as the work of the applet will get done. One disadvantage of Applets is that plugins are required at the client browser for executing applets.

Applets can be executed by browsers running under different platforms.

It works at client side so less response time.

Java applets have been mentioned here for information purposes, but you also need to know that Java applets are deprecated from Java in 2017 and have been completely removed from Java SE 11 (18.9) released in September 2018.

They were introduced in the first version of the Java language, which was introduced in the year 1995. The applet in Java can appear in a frame of the web page, a new application window, Sun's AppletViewer, or a stand-alone tool for testing them.

The browser's Java Plug-in software manages the lifecycle of an Applet. The JApplet class should be used for all applets that use Swing components to construct their graphical user interfaces (GUIs). Swing provides a special subclass of the Applet class called. The Applet class provides the standard interface between the applet and the browser environment. An applet must be a subclass of the class. Applets interact with the user through the AWT and not through the console-based I/O classes. The first import statement is for the Abstract Window Toolkit (AWT) classes. This applet begins with two import statements. After an applet arrives on the client, it has limited access to resources so that it can produce a graphical user interface and run complex computations without introducing the risks of viruses or data security breaching. The applet is usually embedded in an HTML page on a Web site and can be executed from within a browser. The applet is also capable of running in HTML.
