Can an applet start another program on the client?
No, applets loaded over the net are not allowed to start programs on the client. That is, an applet that you visit can’t start some rogue process on your PC. In UNIX terminology, applets are not allowed to exec or fork processes. In particular, this means that applets can’t invoke some program to list the contents of your file system, and it means that applets can’t invoke System.exit() in an attempt to kill your web browser. Applets are also not allowed to manipulate threads outside the applet’s own thread group.

Objects are accessed by getting a handle to the object. Effectively, this is like getting a pointer to an object, but Java does not allow the equivalent of pointer arithmetic on object handles. Object handles cannot be modified in any way by the Java applet or application. • C and C++ programmers are used to manipulating pointers to implement strings and to i
