Java Applets

In order to run an applet, you must have a web browser. An applet can be a completely utilitarian Java application on the grounds that it has the whole Java API’s available to it. There are some essential contrasts between an applet and a standalone Java application, including the accompanying:

  • A main() function is not conjured on an applet, and an applet class won’t define main().
  • An applet is a Java class that extends and enhances the java.applet.applet class.
  • When a client sees a HTML page that contains an applet, the code for the applet is automatically downloaded to the client’s machine.
  • Applets are intended to be inserted inside a HTML page.
  • The JVM on the client’s machine makes an instance of the applet class and conjures different routines amid the applet’s lifetime.
  • The security requirements for an applets are very strict. The security of an applet is frequently alluded to as sandbox security, contrasting the applet with a youngster playing in a sandbox with different decides that must be emulated.
  • A JVM is a base requirement for viewing an applet. The JVM can be either a module of the Web program or a different runtime environment.
  • Other classes that the applet needs can be downloaded in a solitary Java Archive (JAR) file.
