An applet is a small Java program that is intended to be run within a web page. Applets are often used to provide interactive features on websites, such as games or graphical tools. They are embedded in HTML pages and are run within a Java-enabled web browser, or within a Java Applet Viewer. Applets are created using the Java programming language and are typically compiled to bytecode, which can be run on any device that has a Java Virtual Machine (JVM) installed. This allows applets to be run on a wide variety of devices, including computers, phones, and tablets.

Downloading and Installation of Java Applet Viewer on MacOS
To install the Java Applet in macOS, you need to install the Java Development Kit (JDK). The JDK includes the Java Applet Viewer, which allows you to run and test applets. Here’s how to install the JDK in macOS:
Step 1: Open a web browser and then search java JDK 8 download.
Step 2: Select the Java 8 Archive Downloads.
After clicking on the first option java JDK 8 download page will open.
Step 3: Scroll down the page and then you can see there is a different operating system. But here we are choosing Mac OS X x 64.
Step 4: After that accept the License Agreement and download the file.
Step 5: When the download is complete, open the installer package by double-clicking on it. Follow the instructions in the installer to install the JDK. Click on the next button.
Step 6: Now click on the install button to start the installation.
Wait until the installation process is complete.
Step 7: Now as you can see Java installation is successful.
Step 8: When the installation is complete, you can verify that the JDK is installed by opening a Terminal window and typing “java -version”. This should display the version of the JDK that you have installed.
Step 9: To run an applet, you can use the Java Applet Viewer by opening it from the Applications folder or by typing “appletviewer” in the Terminal. Then, open the HTML file that contains the applet code in the Java Applet Viewer. The applet will then be displayed in the viewer window.
