What is difference between java applet and java Swing?

Answer 1

An applet is a Java program embedded in an HTTP document. When the HTTP document is loaded into a web browser, the Java program executes on the web. A widget = window gadget, a GUI (graphical user interface) control. A GUI control, such as a command button, is accessed by the user via a mouse click or by the keyboard. GUI programs can run on one's PC.

Answer 2

applet is for browsers like firefox, chrome or IE

"well, 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. When you use a Java technology-enabled browser to view a page that contains an applet, the applet's code is transferred to your system and executed by the browser's Java Virtual Machine (JVM). For information and examples on how to include an applet in an HTML page, refer to this description of the <APPLET> tag.

The difference between the applet and swing is as mentioned below:

1.Applets are Java programs which are capable of being run within a browser. Swing is a GUI framework.

2. Applet belongs to java.awt package and swing belongs to javax.swing.* package.

3. Applet is a heavy weight component but swing comes under light weight component's category.

4.Swing is a set of classes under JFC that provide lightweight visual component , enable creation of attractive GUI. But Applet is heavyweight component and needs web browser or tool known as AppletViewer."

Answer 3

here are ways of retrieving user-defined property values both at applets and midlets.

The J2SE java.applet.Applet class provides the method public String getParameter(String name).

Parameters are defined at the applet's HTML file.

Example: if the applet is specified as

then a call to getParameter("user") returns the value "Enoch Root".

The J2ME javax.microedition.midlet.MIDlet class provides a similar method: public final String getAppProperty(String key).

It returns the value for the specified key from either its .jad file or the manifest file in the .jar file.

If the same key exists in both places, the value from the Java Application Descriptor (.jad) is returned.

Example: if there is a property

user: Enoch Root

then a call to getAppProperty("user") returns the value "Enoch Root".

If no value exists then both applet and midlet methods return null (note: in case of applets the name argument is case insensitive).

These values can be used to customize an application behavior without the need for recompilation.

Answer 4

an applet runs on a java compatible web browser an application runs on a stand alone computer.

applets do not have main methods while applications execution start with main method

applets are small programs applications are large programs

applets are designed for handling the clients site problems while java applications are designed to work with clients as well as server.

applications are designed to exist in a secure ares while applets are typically used

Answer 5

A Java Applet is a class which is intended to be run from within a web browser. Java Swing is an entire package of classes and interfaces which is dedicated to providing a comprehensive collection of GUI elements.

Answer 6

The major difference between an applet and a widget is that a widget has a host software system. An applet is an application.
