In this tutorial, I am going to show you how to add a Java applet that will play in both Internet Explorer and Firefox as well as other types of browsers and will also validate. We will need to use the <object> tag and its attributes classid, type, width, and height. We will also need the <param> tag and its required name attribute along with the value attribute. We will also need one more thing, which is Internet Explorer’s conditional comments, which I will explain in a bit.

Before I begin, Java is not JavaScript they are two completely different types of technologies. Java is used to create small applications like applets, calculators, clocks, drawing shapes and other types of special effects and more that you can embed and run in your browser. I can write a whole book about Java but in this tutorial, I will just explain how to embed a Java applet to your web page.

The third way to add Java applets to your web pages, only works in Firefox and Mozilla type browsers. We will need to use the <embed> tag and its attributes, which include code, width, height, type and pluginspage.

Now the second method for embedding Flash movies to your web pages involves using the <object> and <param> tags along with their attributes. For instance, the <object> tag has four required attributes, which include height, width, classid and codebase. And the <param> tag has two attributes, which include the required name attribute along with the value attribute. Let me explain the <object> tag and its attributes first and then I will explain the <param> tag and its attributes.
