Java - Applet Basics

An applet is a Java program that keeps running in a Web program. An applet can be a completely useful Java application since it has the whole Java API available to its. 

There are some critical contrasts between an applet and an independent Java application, including the accompanying − 

An applet is a Java class that expands the java.applet.Applet class. 

A primary() strategy isn't conjured on an applet, and an applet class won't characterize fundamental(). 

Applets are intended to be inserted inside a HTML page. 

At the point when a client sees a HTML page that contains an applet, the code for the applet is downloaded to the client's machine. 

A JVM is required to see an applet. The JVM can be either a module of the Web program or a different runtime condition. 

The JVM on the client's machine makes an example of the applet class and conjures different techniques amid the applet's lifetime. 

Applets have strict security decides that are implemented by the Web program. The security of an applet is frequently alluded to as sandbox security, contrasting the applet with a tyke playing in a sandbox with different standards that must be taken after.
