You have two options:
1. to use appletviewer which comes with your JDK to just see the applet work in a bare-bones browser
2. embed the applet tag in your HTML page.

<html>
    <title>My Applet</title>
    <body>
        <applet code="PrintApplet.class" width="400" height="400"></applet>
    </body>
</html>

But as it stands, <applet> has been deprecated.
So, here is what you do:
1. Add this to your <head> : <script src="http://java.com/js/deployJava.js"></script>
2. Add this to your <body>:

<script>
    var attributes = {codebase:'http://my.url/my/path/to/codebase',
                      code:'my.main.Applet.class',
                      archive: 'my-archive.jar',
                      width: '800', 
                      height: '600'};
    var parameters = {java_arguments: '-Xmx256m'}; // customize per your needs
    var version = '1.5' ; // JDK version
    deployJava.runApplet(attributes, parameters, version);
</script>

Again, as of HTML5, <head> is not needed so you can just type <script>....</script>
