Change an int array to an int integer

An interview question:

The Java implementation transforms an int array into an int integer. For example: int[] arr = new int[]{1,2,3,4,5}; Becomes 12345

/** * created by leo on 15/10/27. */public class interview {     public static void main (String[] args)  {         system.out.println (parseint (new int[]{1,2,3,4,5}));         system.out.println (Integer.parseint ("12345"));    }     /**     * 12345     *  @param  arr      *  @return      */    public  static final int parseint (Int[] arr) {         int length = arr.length;        int total  = 0;        for  (int i = 0; i  < length; i++) {            int num = arr[i];             total = total +  Calculateweightnum (num, length -  (i + 1))  ;         }        return total;    }     private static int calculateweightnum (int num , int  Numoften) {        int result = num;         for  (int i = 0; numoften > 0 & & i < numoften; i++) {             result = result * 10;        }         return result;    }}
