copying array by value in java

Question

I tried to make an independent copy of an array but couldnt get one. see i cannot copy it integer by integer using a for loop because of efficiency reasons. Is there any oth

Answer 1

You can use System.arraycopy, but I doubt it will be much more efficient. The memory has to be copied anyways, so the only optimization possible is to copy bigger chunks of memory at once. But the size of a memory chunk copied at once is strongly limited by the processor/system-architecture.
