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?

To divide an array into two, we need at least three array variables. We shall take an array with continuous numbers and then shall store the values of it into two different variables based on even and odd values.
Using the copyOfRange() method you can copy an array within a range. This method accepts three parameters, an array that you want to copy, start and end indexes of the range. You split an array using this method by copying the array ranging from 0 to length/2 to one array and length/2 to length to other.
splice() actually removes elements from the source array, the remaining elements in the array will be the elements for the right half. Math. floor() will round down to give the left side one less than the right side for odd lengths. You could use Math.
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); If you love us?
