I have already done a bunch of tutorials and I know c++ which seems pretty similar to java. The way I have been running my .class files are just using the applet tag and putting the .class in it. Heres an example of one html code I have used:
<applet code="BallMover.class" width="300" height="300">
I just don't understand jar files. I don't know how JVM would know when I want each different .class file to be ran. Is there like a run function that runs a differen't .class file or something?
