Split array into two parts without for loop in java

Question

I have an array of size 300000 and i want it to split it into 2 equal parts. Is there any method that can be used here to achieve this goal?

Will it be faster than the for-loop operation or it will cause no effect on performance?

Answer 1

You can use System.arraycopy().

int[] source = new int[1000];  int[] part1 = new int[500]; int[] part2 = new int[500];  //              (src   , src-offset  , dest , offset, count) System.arraycopy(source, 0           , part1, 0     , part1.length); System.arraycopy(source, part1.length, part2, 0     , part2.length);
