* Demonstrates how to read applet parameters. The next listing shows the Java code for the ParamTest.java file. Next, let's look at the Java applet code needed to read the parameters being passed to it. IntelliJ IDEA PSI Viewer Konstantin Bulenkov If you’re an IntelliJ IDEA plugin developer, you’re surely going to enjoy IntelliJ IDEA PSI Viewer (Tools -> View PSI Structure), which displays internal structure of various files, as they’re interpreted by IntelliJ IDEA. So far we've seen to create the HTML code that (1) invokes a Java applet using an applet tag, and (2) passes parameters to the applet. As a final note, notice that the tags are enclosed within the tags. These names and values can be whatever we want - whatever makes sense for your applet. Then, the only thing we need to do to pass parameters to the applet are to include the name and value of the desired parameters in tags. Java applet example - Passing applet parameters to Java appletsĪs you can see, the HTML file identifies the Java applet that we want to load - AppletParameterTest.class using an APPLET tag. We name this file AppletParameterTest.html. The listing below shows the source code for the sample HTML file we created for this article, including the applet tag shown. Hopefully you'll be able to use this same technique to make your own applets more flexible and portable. In this brief applet tutorial, we'll show you how to pass applet parameters from an HTML page to a Java applet. On the other hand, if you don't pass parameters into a Java applet, how will the applet know what font to use? Simple - you hardwire it into the Java source code! As I often say to my new puppy at home, "this is bad". If you pass parameters into your Java applets, they can be portable from one web page to another, and from one web site to another. For instance, you may want to tell the applet what background color it should use, or what font to use, to keep your Java applet consistent with the rest of your HTML-based web site.Ī great benefit of passing applet parameters from HTML pages to the applets they call is portability. Many times when you're developing a Java applet, you want to pass parameters from an HTML page to the applet you're invoking. Help keep this website running at ! Introduction The Applet class must be the superclass of any applet that is to be embedded in a Web page or viewed by the Java Applet Viewer.
