A J2EE component that typically executes in a Web browser but can execute in a variety of otherapplications or devices that support the applet programming model.

In Advanced Java, an “applet container” typically refers to the environment or platform that hosts and manages Java applets. An applet is a small Java program that is embedded within an HTML page and is intended to be executed within a web browser. The applet container is responsible for loading, initializing, and running the Java applet.

In the context of Advanced Java, applets have become less common due to security concerns and the widespread adoption of other web technologies like JavaScript and HTML5. However, understanding the concept of an applet container is still relevant for historical context and for those who may encounter legacy systems or older codebases.

In the context of modern Java development, particularly for web applications, the focus has shifted to technologies like servlets, JavaServer Faces (JSF), and other frameworks for building dynamic and interactive web applications.
