I am trying to run some old java applets from the old book "Algorithms and Data Structures In Java" by Robert LaFore.
I have JDK 1.8 / Java 8 installed and it includes appletviewer.exe
I don't have any recollection of how one would run them.
I've got appletviewer.exe in my path.

As another route I just tried https://sourceforge.net/projects/portableapps/files/Mozilla%20Firefox%2C%20Portable%20Ed./ Mozilla Firefox, Portable Edition 220.127.116.11 2007-10-22
But Firefox doesn't come with the plugin and can't install it
Going back to trying with appletviewer, I found from googling that error, that appletviewer is meant to run be given an HTML file.
So I tried
And I get
C:\aaa>Appletviewer Array.html java.lang.NoClassDefFoundError: personGroup at Array.init(Array.java:746) at sun.applet.AppletPanel.run(AppletPanel.java:434) at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.ClassNotFoundException: personGroup at sun.applet.AppletClassLoader.findClass(AppletClassLoader.java:219) at java.lang.ClassLoader.loadClass(ClassLoader.java:418) at sun.applet.AppletClassLoader.loadClass(AppletClassLoader.java:152) at java.lang.ClassLoader.loadClass(ClassLoader.java:351) ... 3 more
I tried jd-gui-windows-1.6.6 and opened Array.class and I see that it has
private personGroup thePersonGroup;
At this URL
No doubt that is a reference to a file system
Chap02/Array/Array.class but I can't see any personGroup.class or personGroup.java
