Difference Between Applet and Servlet in Java

In this post, we will understand the difference between applet and a servlet in Java.

Applet

• They are executed on client-side.

• It runs within a Web browser.

• It runs on the client machine.

• Its parent packages are ‘java.applet.*’ and ‘java.awt.*’.

• Some methods include init(), stop(), paint(), start(), destroy().

• A user interface is needed to execute an applet.

• User interface examples are AWT or swing.

• It requires user interface on client machine to execute the applet.

• This is done since it needs more bandwidth.

• They prone to risk since they are executed on the client machine.

Servlet

• It is executed on the server-side.

• It runs on the web Page.

• It runs on the server.

• Its parent package includes ‘javax.servlet.*’ and ‘java.servlet.http.*’.

• Some of the life cycle methods include init(), service(), and destroy().

• It doesn’t need an interface to execute.

• Since they are executed on servers, they need less bandwidth.

• They are more secure in comparison to applet since they are under the security of server.
