Applets are written in a language different from the scripting or HTML language that invokes it. The applet is written in a compiled language, whereas the scripting language of the container is an interpreted language, hence the greater performance or functionality of the applet.
Java Applets were small programs written in Java that ran inside a web browser. Learning about Applet helps us understand how Java has evolved and how it handles graphics. Note: java.applet package has been deprecated in Java 9 and later versions, as applets are no longer widely used on the web.
Applets are tiny computer programs that fulfill a particular function. They have limited functionality and are generally embedded into a larger program or software platform. This enables applets to function swiftly and consistently without using a significant amount of system resources.
When you use a Java technology-enabled browser to view a page that contains an applet, the applet's code is transferred to your system and executed by the browser's Java Virtual Machine (JVM).
The entire java.applet package has been removed from JDK 26, which will release in March 2026. JDK 25 (an LTS release depending on your vendor) is the last Java SE version to include the java.applet API. This was done under JEP 504: Remove the Applet API and the reasons behind the removal as well as its timing deserve an explanation. A Bit of Background About Applets The java.applet.Applet ...
What is an applet? An applet is a small computer program that performs a specific task. It is typically embedded within another larger app or software platform and has limited functionality. This allows applets to run quickly and reliably without demanding a lot of system resources.
The Applet class provides a framework for applet execution, defining methods that the system calls when milestones -- major events in an applet's life cycle -- occur.
Java applets are small applications written in the Java programming language, or another programming language that compiles to Java bytecode, and delivered to users in the form of Java bytecode.
