What are the advantages and disadvantages of using a Java-Applet for chat functionality instead of PHP?

One advantage of using a Java-Applet for chat functionality is that it can provide a more interactive and dynamic user experience compared to PHP. However, Java-Applets require the user to have Java installed on their browser, which can be a disadvantage as it may not be supported on all devices or browsers. Additionally, Java-Applets can be more complex to develop and maintain compared to PHP.
