Java applet

Java applet - Technical information 1 Java applets are executed in a sandbox by most web browsers, preventing them from accessing local data like clipboard or file system. The code of the applet is downloaded from a web server and the browser either embeds the applet into a web page or opens a new window showing the applet's user interface.

Java applet - Technical information 1 A Java applet extends the class java.applet.Applet, or in the case of a Swing applet, javax.swing.JApplet. The class must override methods from the applet class to set up a user interface inside itself (Applet) is a descendant of Panel which is a descendant of Container. As applet inherits from container, it has largely the same user interface possibilities as an ordinary Java application, including regions with user specific visualization.

Java applet - Example 1 The following example is made simple enough to illustrate the essential use of Java applets through its java.applet package. It also uses classes from the Java Abstract Window Toolkit (AWT) for producing actual output (in this case, the "Hello, world!" message).

Java applet - Disadvantages 1 Some browsers, notably mobile browsers running Apple iOS or Android do not run Java applets at all.

Java applet 1 Java applets were introduced in the first version of the Java language in

Java applet 1 They are usually written in Java (programming language)|Java but other languages such as Jython,[ dex.html Jython applet page] JRuby,[ jruby-inside-an-applet/ About Java applets in Ruby] Scala (programming language)|Scala or Eiffel (programming language)|Eiffel (via SmartEiffel)[ A tool to produce Java applets with SmartEiffel] may be used as well.

Java applet 1 Until approximately 2011, Java applets had been many times faster than JavaScript.[ ctalBenchmark.html An example of the 2005 year performance benchmarking] Unlike JavaScript, Java applets have access to 3D hardware acceleration, making them well suited for non-trivial, computation intensive visualizations

Java applet 1 Since Java's bytecode is cross-platform (or platform independent), Java applets can be executed by browsers (or other client (computing)|clients) for many platforms, including Microsoft Windows, FreeBSD, Unix, OS X and Linux. It is also trivial to run a Java applet as an application software with very little extra code so that it can be run directly from the integrated development environment (IDE).

Java applet - Technical information 1 Java applets are executed in a sandbox (security)|sandbox by most/all web browsers, preventing them from accessing local data like clipboard (software)|clipboard or file system. The code of the applet is downloaded from a web server and the browser either compound document|embeds the applet into a web page or opens a new window showing the applet's user interface.

Java applet - Technical information 1 A Java applet extends the class, or in the case of a Swing (Java)|Swing applet,. The class must override methods from the applet class to set up a user interface inside itself (Applet) is a descendant of which is a descendant of. As applet inherits from container, it has largely the same user interface possibilities as an ordinary Java application, including regions with user specific visualization.

Java applet - Embedding into a web page 1 Deprecating applet tag has been criticized.[ JECT Criticism] of APPLET tag deprecation Oracle now provides a maintained JavaScript code[ Java applet launcher from Oracle - Link Broken!] to launch applets with cross platform workarounds.

Java applet - Example 1 Simple applets are shared freely on the internet for customizing applications that support plugin (computing)|plugins.For example, see [ Java applet section in Wikiversity]

Java applet - Advantages 1 A Java applet can have any or all of the following advantages:[ deployment/applet/index.html Oracle official] overview on Java applet technology

Java applet - Disadvantages 1 *Some browsers, notably mobile browsers running iOS (Apple)|Apple iOS or Android (Operating System)|Android do not run Java applets at all.[ _mobile.xml]

Java applet - Unsigned 1 Communities may solve this problem via Code review|source code review or running applets on a dedicated domain.[ Proposal:Java_applet_support Strategy.Wikimedia.org], proposal with discussion about Java applets in community sites[ Ultrastudio.org], user editable educational site with full applet support

Java applet - Alternatives 1 Of these, JavaScript is not always viewed as a competing replacement; JavaScript can coexist with applets in the same page, assist in launching applets (for instance, in a separate frame or providing platform workarounds) and later be called from the applet code.[ html Rgagnon.com], calling a Java applet from JavaScript JavaFX is an extension of the Java platform and may also be viewed as an alternative.

Comet (programming) - Early Java applets 1 The ability to embed Java applets into browsers (starting with Netscape 2.0 in March 1996http://web.archive.org/web/ /www27.netscape.com/comprod/products /navigator/version_2.0/index.html Netscape.com from 1996 (via Archive.org)) made real-time communications possible, using a raw Transmission Control Protocol|TCP sockethttp://java.sun.com/j2se/1.4.2/docs/api/ java/net/Socket.html to communicate between the browser and the server

Applet - Java Applet 1 Since Java's bytecode is platform- independent, Java applets can be executed by browsers running under many platforms, including Microsoft Windows|Windows, Unix, Mac OS, and Linux

Applet - Java Applets 1 A Java applet contains different security models: Java_applet#Unsigned|unsigned Java applet security, Java_applet#Signed|signed Java applet security, and Java_applet#Self_signed|self signed Java applet security.
