Hi guys! I was working in LAB-1010. And I was surprised when I run "Exercise 3.1 - Call methods of the System class" and get the following result: Time for manual copy: 18 ms. Time for copy utility provided: 86 ms. As you can see, it seems to be the manual copy is more efficient than arraycopy() method. Then, I check the code again, but I didn't find errors.
What is happening? (My hardware is AMD Athlon(TM) XP 2500+ CPU (RAM 1 GB) with openSuse 11.2 O.S. and jdk1.6.0_17.) Thank you in advance. -- [Adrián E. Córdoba]
