A First Java Program

We start by writing what is called a Java applet. This is a form of a Java program that can be embedded in a HTML document and accessed from the web. An example HTML document that calls our example applet is shown below:

			<HTML>
			<HEAD>
			<TITLE>Demo Applet</TITLE>
			</HEAD>
			<BODY>

			<H1>Demo Applet</H1>
			<P>My favorite class is 6.837</P>
			<HR>
			<CENTER>
			
			<APPLET code="Demo.class" width=200 height=200>
			</APPLET>
			
			</CENTER>
			<HR>
			</BODY>
			</HTML>
	
    The italicized lines add the Java applet to our document. Notice the .class extension. All Java source code files should end with a .java extension. The source is here.
