Java Applets are also the so-called Java byte codes. They are just delivered in the form of byte codes during execution as they are being run in web browsers through the use of the Java Virtual Machine or the JVM. The Java Applets area also tested through the Sun’s Applet Viewer, which serves as a stand alone tool in testing Java Applets.
When the first version of Java programming language was introduced in the year 1995, the Java Applets was also introduced. The Java Applets are normally written in the programming language of Java. However, they can also be written in some other form of languages that compile the Java byte codes called the "Jython".
The Java Applets are the one providing the interactive features to some web applications that HTML cannot provide. They can also be executed in many platforms by web browsers as the byte codes of Java technology are platform independent. Among the platforms that can be executed by Java Applets include the Linux, Mac OS, UNIX and Windows. Open source tools like the applet2app are used in converting Java Applets to a Java application, and Linux and Windows executable stand alone. These tools have the advantage of running Java Applets in offline mode without the requirement of using internet browser software. There is also the server-side applet called the Java Servlet that also has the characteristics of the Java Applets. The only difference is its’ functions, language and some other characteristics.
In the "sandbox" of most web browsers, the Java Applets are being executed that prevents them the access from any local data. The execution involves the downloading of the codes of the Java Applets from the web server as well as from the web browser. After all the codes of the Java Applets are downloaded, the web browser either opens another window that shows the user interface of the applets or embeds the Java Apple into the page of the web. The Java Applets are displayed on the page of a web with the use of the detracted HTML element or any recommended object element. Through this, the sources of the Java Applets as well as the location statistics are specified.
The Java Applets may also have some advantages. One of its main advantages is its simplicity to work on different operating systems of Mac OS, Linux, UNIX and Windows. Java Applets are also platform independent that it can perform cross-over in different platforms. They can also work on all installed versions of Java technology running at the same time rather than just the version of plug-ins.
