Applet’s Life Cycle
- Once the applet has loaded, the init() method is called. used to serve as an initialization.
- When the applet is relaunched and after init(), start() is called. utilized to initiate or continue applet execution.
- To redraft the applet, call paint(Graphics g). The content of the applet is shown there.
- When the applet is no longer visible or active, the stop() method is called.
- When the applet is stopped, such as by closing the browser or leaving the page, the destruct() method is called.
Displaying and Loading
The applet> tag, which is no longer supported, was used to embed applets into HTML pages. This tag defined the class, size, and other details of the applet. Later, to accomplish the same task, the <object> and <embed> tags were introduced.
Security
A security sandbox environment keeps applets from carrying out dangerous actions on the client’s computer while they are running. The user’s filesystem, network access, and other actions are restricted in this sandboxed environment. Applets had to be digitally signed in order to perform additional functions outside of the sandbox, and users had to give express consent.

A Java applet is a little application created in the Java programming language and run on a web browser while embedded in an HTML page. In essence, it’s a method for introducing Java’s “write once, run anywhere” feature to the world of web browsers.
Components and Organization
- Applets are subclasses of the ‘java.applet.Applet’ class.
- For their graphical user interface, they can use either the AWT (Abstract Window Toolkit) or Swing frameworks, however, AWT has a smaller environmental impact and was previously more popular.
