Given the code fragment:
What is the result?
- A. 10 : 10
- B. Compilation fails
- C. 5 : 5
- D. 5 : 10
Answer: A
Explanation:
The variable i is local to all instances of class Test so each time we create an instance, i=0 and the loop add 5 to count.
The variable count (static) is global to all instances of class Test and all instances share the same variable. It's been initialized only once to zero an retains its value between the calls to changeCount Since we call two times the method changeCount, the final result is 10 : 10
