What is the difference between applet and JApplet?
A JApplet expects to be embedded in a page and used in a viewing environment that provides it with resources. In all other respects, however, applets are just ordinary Panel objects. As Figure 23-1 shows, an applet is a kind of Panel .
A Java Application is a type of program that can get independently executed on a computer. A Java Applet is a small program that makes use of another application program so that we can execute it. The execution of the Java application begins with the main() method.
JPanel vs JFrame both are commonly used classes available in java; JPanel can be considered as a general container, which is used in case of complex or bigger functions which require grouping of different components together; on the other hand, JFrame is generally used to host simple elements used in a window like a ...
JApplet is a java swing public class designed for developers usually written in Java. JApplet is generally in the form of Java bytecode that runs with the help of a Java virtual machine (JVM) or Applet viewer from Sun Microsystems. It was first introduced in 1995.

The APPLET tag should be written in the source code file, with comments around it.
- Write HTML APPLET tag in comments in the source file.
- Compile the applet source code using javac.
- Use applet viewer ClassName. class to view the applet.
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.
An applet is a Java program that can be embedded into a web page. It runs inside the web browser and works at client side. An applet is embedded in an HTML page using the APPLET or OBJECT tag and hosted on a web server. Applets are used to make the website more dynamic and entertaining.
The difference between Applet and Application is that Applet is a small java program that can be run by a Java-compatible web browser while application is a standalone program that can directly run on the machine.
Examples of Web-based applets include: QuickTime movies. Flash movies. Windows Media Player applets, used to display embedded video files in Internet Explorer (and other browsers that supported the plugin)
An applet container is the environment that runs a Java applet and provides secure applet execution. Examples include Web browsers and the applet viewer in Java's software development kit (SDK). The applet container uses the sandbox security model, preventing applets from accessing system resources and causing harm.
What is the difference between applet and frame?
An applet must be a public class, frame doesn't have to. In an applet, construction happens in the init() method; in the frame, it's in the constructor. The browser starts the applet. You start the frame from main() or another method.
FlowLayout. The flow layout is the default layout manager for all Panel objects and applets.
What is an Applet? A java applet is program that can be included in a HTML page and be executed in a java enabled client browser. Applets are used for creating dynamic and interactive web applications.
The browser, as a runtime, has become powerful enough to make Java Applets unnecessary. Modern webapps with some amount of JavaScript on the frontend replaced Java Applets.
Overview. The applets are used to provide interactive features to web applications that cannot be provided by HTML alone. They can capture mouse input and also have controls like buttons or check boxes. In response to user actions, an applet can change the provided graphic content.
- To run an applet with the Applet Viewer, enter the following command: appletviewer <name> , where <name> is one of the following options: The file name of an HTML file that calls an applet. ...
- To debug an applet with the Applet Viewer, use the debug parameter with the appletviewer command.
...
They will be the same for every applet you make:
- Write the Java code in a text file.
- Save the file.
- Compile the code.
- Fix any errors.
- Reference the applet in a HTML page.
- Run the applet by viewing the web page.
...
Advantage of Applet
- It works at client side so less response time.
- Secured.
- It can be executed by browsers running under many plateforms, including Linux, Windows, Mac Os etc.
The applet element was deprecated in HTML 4.01 and rendered entirely obsolete by HTML5. Support for the Java browser plugin has been dropped by virtually all leading web browsers.
The applet life cycle can be defined as the process of how the object is created, started, stopped, and destroyed during the entire execution of its application. It basically has five core methods namely init(), start(), stop(), paint() and destroy().These methods are invoked by the browser to execute.
Is applet available in Java?
An applet is a program written in the Java programming language that can be included in an HTML page, much in the same way an image is included in a page.
swing has been deprecated and marked for removal.
AppletViewer is a standalone command-line program from Sun to run Java applets. Appletviewer is generally used by developers for testing their applets before deploying them to a website. As a Java developer, it is a preferred option for running Java applets that do not involve the use of a web browser.
The contentPane should be the parent of any children of the JApplet . As a convenience, the add , remove , and setLayout methods of this class are overridden, so that they delegate calls to the corresponding methods of the ContentPane .
Short answer: Applets are intended to be small bits of functionality run in a web browser and downloaded on-demand. Swing is a collection of user interface components, like text boxes and windows, that are meant to be assembled by a developer for use on the desktop.
No, there isn't.
It was simple to make it work on FreeBSD, Linux, Microsoft Windows and macOS – that is, to make it cross-platform. Applets were supported by most web browsers through the first decade of the 21st century; since then, however, most browsers have dropped applet support for security reasons.
Save this answer. Show activity on this post. In short, this is because many main stream browsers had either removed or planned to remove standards based plugin support, therefore Oracle wants Java developers to migrate from Java applets to plugin-free Java Web-start technologies.

A JVM is required to view an applet. The JVM can be either a plug-in of the Web browser or a separate runtime environment. The JVM on the user's machine creates an instance of the applet class and invokes various methods during the applet's lifetime.
What is the disadvantage of applet?
Applets cannot stream data directly into the browser. Applets cannot subscribe to events detected by the browser that are triggered outside of the applet area. For example, applets cannot detect that a user followed a bookmark. Similarly, applets cannot detect that a user typed in a URL that should be followed.

There are two types of applets: local applets and remote applets.
Swing is a lightweight Java graphical user interface (GUI) that is used to create various applications. Swing has platform-independent components. It enables the user to create buttons and scroll bars. Swing includes packages for creating desktop applications in Java.
Swing in java is part of Java foundation class which is lightweight and platform independent. It is used for creating window based applications. It includes components like button, scroll bar, text field etc. Putting together all these components makes a graphical user interface.
