i have array, want divide smaller arrays of n size, , perform operation on each. current method of doing is implemented arraylists in java (any pseudocode do) (int = 1; <= math.floor((a.size() / n)); i++) { arraylist temp = subarray(a, ((i * n) - n), (i * n) - 1); // stuff temp } private arraylist<comparable> subarray(arraylist a, int start, int end) { arraylist toreturn = new arraylist(); (int = start; <= end; i++) { toreturn.add(a.get(i)); } return toreturn; } where list, n size of desired lists i believe way taking time when working considerably large lists (of 1 million in size) i'm trying figure out more efficient. you'll want makes use of list.sublist(int, int) views rather copying each sublist. easily, use guava 's lists.partition(list, int) method: list<foo> foos = ...

hi im confused abt method have create. have create histogram array num division categories i.e selecting reasonable integer range , step size numdivisons cover whole range of elements in array. @return array histogram in position contains * number of observations in division */ example: {1,3,4,5,10,15,17}. if numdivisions=2 need divide range (1 17) 2 divisions. example, range 0 10 (not included) , 10 20. in case there 4 values in range 0 <10 , 3 values between 10 , 20. histogram numdivisions=2 array {4,3}. public int[] histogram(int numdivisions) can tell me best method of doing it? thanks simple: get minimum , maximum elements of array take difference , divide num, obtaining "step" now iterate through array, placing number n in slot such * step <= n - min < (i+1) * step
