9 Difference between Applet and Application in Java
In this article, I will be explaining the complete difference between Applet and Application in Java along with coding examples. Before to this, let’s see the definition of Java applet and application.
What is Java Applet?
An applet is a small application that performs specific operations or functions. It is a utility program which loaded from the web server and executed by the web browser.
Applets are designed to be embedded within the HTML page, thereby, providing functionalities that a simple HTML page cannot provide.
What is an Application in Java?
A Java application is a standalone java program that runs on client or server.
It is a program that runs on itself as and when the main() method of any specific class is executed. An application has a functionality that benefits user or some other java application.
Still confused? Let’s see the differences…
Difference between Applet and Application in Java:
In other words, how is Java Applet different from Java Application?
The major differences between an applet and an application in JAVA are as follows:
| Sr.No. | Characteristic | Java Application | Java Aapplet |
|---|---|---|---|
| 1. | Definition | An application is a standalone Java program which can be run independently on client/server without the need of a web browser. | An applet is a form of Java program which is embedded with HTML page and loaded by a web server to be run on a web browser. |
| 2. | main() method | The execution of the program starts from the main() method. | There is no requirement of main() method for the execution of the program. |
| 3. | Access Restrictions | Application can access local disk files/ folders and network system. | Applet doesn’t have access to the local network files and folders. |
| 4. | GUI | It doesn’t require any Graphical User Interface (GUI). | It must run within GUI. |
| 5. | Security | It is a trusted application and doesn’t require much security. | It requires high-security constraints as applets are untrusted. |
| 6. | Environment for Execution | It requires Java Runtime Environment (JRE) for its successful execution. | It requires a web browser like Chrome, Firefox, etc for its successful execution. |
| 7. | Installation | It is explicitly run and installed on a local system.An applet doesn’t have access to local files and so it cannot perform read and write operations on files stored on local disk. | It doesn’t require any explicit installation to be done. |
| 8. | Read/ Write Operation | An application can perform read and write operations on files stored on the local disk. | An applet doesn’t have access to local files and so cannot perform read and write operations on files stored on local disk. |
9. Examples [Java Applet Vs Application]:
Here are examples of Java application and applet. You can test these programming codes by running on your system.
Java Application Code Example:
public class MyApplication {
public static void main(String args[ ])
{
System.out.println(“Hello, Welcome to csestack.org”);
}
}
Java Applet Code Example:
import java.awt.*;
import java.applet.*;
public class Myclass extends Applet {
public void init() { }
public void start() { }
public void stop() {}
public void destroy() {}
public void paint(Graphics g) {}
}
Conclusion:
Java Applications and Java Applets in perspective with Java are two varied types of programs which are different in function. But both have their own particular usage and magnitude.
