It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. See the FAQ for guidance on how to improve it.

Only if either:

  • You explicitly grant the applet increased rights (this also requires the applet to be cryptographically signed, which in theory allows you to find out who wrote it and sue them when it turns out to be damaging)
  • Your JVM has a security hole that the applet exploits

No. Java has a built in security mechanism will prevents applets from performing certain method calls. See the documentation for Runtime#exec(), for example.

Java runs in a "Sandbox" and can't take over your computer.
