java - Giving Position to values in an ArrayList -

-

i'm working on assigning positions values in arraylist in java.

for example arraylist containing {5,6,3,1,9,10,0,2,6}.

how can correctly assign positions numbers have {5th,3rd,7th 2nd,1st,8th, 6th,3rd}.

i have sorted arraylist containing numbers in java.

am stuck @ giving position numbers.

so work?

    public static arraylist<string> getpositions(arraylist<integer> list) {     arraylist<string> positions = new arraylist<string>();     string[] endings = { "th", "st", "nd", "rd" };     integer last = 100;     integer lastrank = 1;     (int index = 0; index < list.size(); index++) {         int position = index + 1;         if (last == list.get(index)) {             position = lastrank;         }         int remainder = position % 10;         string rank = position + "";         string ending = endings[0];         if (remainder <= 3) {             if ((position % 100) - remainder != 10) {                 ending = endings[remainder];             }         }         rank = rank + ending;         last = list.get(index);         lastrank = position;         positions.add(rank);     }     return positions; }

i give credit robert van der spek coming more efficient way assign ending of position.

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
