Differentiate java applets from java application?
Distinguishing Java Applets from Java Applications - AchieversIT
Java Applets and Java Applications are two distinct types of Java programs, each with its own characteristics and use cases. Here's a breakdown of the key differences between Java Applets and Java Applications:
Purpose and Use:
Java Applets: Java Applets are designed to be embedded and executed within web browsers. They are primarily used for creating interactive content on web pages, such as animations, games, or small applications.
Java Applications: Java Applications are standalone programs that are intended to run independently on a user's computer or server. They are not embedded in web browsers and serve a wide range of purposes, from desktop software to backend server applications.
Execution Environment:
Java Applets: Java Applets run in a controlled environment within a web browser. They are subject to certain security restrictions and must be executed with a Java plugin. Browser support for Java Applets has decreased in recent years.
Java Applications: Java Applications run on a Java Virtual Machine (JVM) installed on the user's computer or server. They are not constrained by web browser limitations and have more direct access to system resources.
User Interaction:
Java Applets: Java Applets are designed for user interaction within web pages. They can respond to user events like clicks and keyboard input, making them suitable for creating dynamic web content.
Java Applications: Java Applications can be interactive and accept user input through graphical user interfaces (GUIs) or command-line interfaces. They are versatile for creating various types of software.
Deployment:
Java Applets: To deploy a Java Applet, it needs to be embedded in an HTML web page using the tag. Users may need to have the Java plugin installed to run Applets.
Java Applications: Java Applications are deployed as executable JAR (Java Archive) files or through installers. Users typically run them directly from their desktop or command line.
Access to System Resources:
Java Applets: Java Applets operate within a sandboxed environment with restricted access to system resources for security reasons. They cannot perform operations like file I/O without user permissions.
Java Applications: Java Applications have more extensive access to system resources and can perform operations such as file I/O, network communication, and hardware interaction, based on user permissions.
Web Browser Support:
Java Applets: Browser support for Java Applets has significantly declined over the years due to security concerns and the rise of alternative web technologies like HTML5 and JavaScript.
Java Applications: Java Applications do not rely on web browsers and are not subject to browser-related compatibility issues.
In conclusion, Java Applets and Java Applications serve different purposes and operate in distinct environments. Java Applets are designed for web-based interactivity within browsers, while Java Applications are standalone programs for a wide range of software development purposes. AchieversIT provides comprehensive Java training that covers both Java Applet development and Java Application development, equipping students with the skills needed for various programming scenarios.
