erlang lists:dropwhile weird result -


can please me understand what's going on here

lists:dropwhile(fun(x) -> x < 8 end, lists:seq(1,10)).  "\b\t\n" % ??? ? why not [8,9,10]  lists:dropwhile(fun(x) -> x < 7 end, lists:seq(1,10)).    [7,8,9,10] % correct

your results correct in both cases. unexpected string in first case due fact in erlang strings lists of integers. therefore, erlang chooses interpret first list string, since contains printable ascii codes. in second case list contains code 7, not printable, erlang forced interpret integer list.

you can print actual integer list using

mylist = lists:dropwhile(fun(x) -> x < 8 end, lists:seq(1,10)), io:format("~w", [mylist]).

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
