Can Opera run Java applets?
Yes it supports Java though like Web 2.0 it requires you install the EPOC Java Runtime Environment first. If this isn’t installed and you load a page containing an applet, a message will appear in the top right-hand corner telling you that Java is not available. Also since Opera itself has a far greater RAM overhead than Web 2.0 you may require more memory to run the same applets. If there isn’t enough RAM, or available memory drops too low after the applet is loaded it will simply disappear.
