Hi all I have one question.
Which one of the following operations is NOT supported by java.lang.Runtime?

a) Execute native operating system commands.

b) Dynamically unload Class files.

I am little bit confuse about this
We have exec method in this class so that we can execute programme like notepad ,calculator etc

and we have runfinalization for any objects pending finalization.

so what may be the answer for this question?

Is this a SCJP question? java.lang.Runtime is not on SCJP objective list.
You may get your answer in Beginner Forum.

Thanks,
