问题 Hello everyone my name is Fyree! I have an assignment for an introductory Java course where I need to create a program that takes user input for the beginning values, and all five year values to make a line graph (but that is for another post), and also print the rate.

TLDR: How to post .jar file on website, & if you do so via applet, can someone who cannot edit the site create an applet for the website? If it is the

问题 Of all these methods what's being run and in what order?? I guess the first question to ask is whats being run first?

问题 So I am creating this applet which I want to have full on swing components in it. I have looked at all the docs, I have made the applet, and I can get something to show up in it if I override the update(Graphics g) method, but simply adding components to the contentPane doesn't seem to be doing it!

问题 I am trying to do some automated testing with selenium on a site that has a java applet. Specifically, I want to test different java versions on different browsers. It is relatively easy to change the jre that is being used by local applications/commandline - usually just a modification of the PATH and perhaps a registry tweak (HKEY_LOCAL_MACHINE/SOFTWARE/JavaSoft/Java Runtime Environment/CurrentVersion seems to need to be changed sometimes).
