mock: garbage collector

[adam Lui]

source : learnKey

which request(s) that the garbage collector executes?
A. System.gc();
B. System.runGC();
C. System.getRuntime().gc();
D. Runtime.gc();
E. Runtime.runGC();
F. Runtime.getRuntime().gc();

I picked A, F in the mock exam,
but since it didnt auto save the report and i closed the software by accident,
i am not sure the answers.

[Gaurav Bhatia]

A and F are correct.
Try compiling the code.

[Jari Timonen]

A and F are correct.

[Fu Dong Jia]

A and F are correct.

[Raghavan Muthu]

Yes, A and F are correct though C seems to be so!

I assume option D is also right

Nope. Runtime's gc() method is a non-static method, so you can't invoke it without an instance of Runtime.
