Comparing arrays that have same elements in different order

Question

I wrote below code to compare to arrays that have same elements but in diff order.

 Integer arr1[] = {1,4,6,7,2};
 Integer arr2[] = {1,2,7,4,6};

Answer 1

You are reinventing wheel to sort arrays.

Use

java.util.Arrays.sort(T[] a, Comparator c)

also there are methods to sort primitive types such as int.
