Given the code. Which line of code marks the earliest point that an object referenced by myInt becomes a candidate for garbage collection?



A) Line 4
B) Line 5
C) Line 6
D) Line 7
Correct answer:7

i think answer should be line 4
because
first, myint---->new Integer(0) //first object
then
myint------>new Integer(1)

so on till ----> new Integer(4)

so after first object would be eligible for GC line 4

OCPJP 6.0 93%
OCPJWCD 5.0 98%

after line 4 myint is assigned to arr[i] at line 5 so object reffered by myint has another reference at line 5 and hence it cant be GCed until the method has completed.


SCJP 1.6 96%

What does "scjptest" mean? Is this from the actual exam?
