data structures - java file input pair of numbers linkedlist -


i've been looking around , can't seem find best answer problem i'm doing. have .txt file need read in, looks little this:

1,10 5,16 2,7 4,12 3,19

now i'm supposed create linked list fine, biggest problem i'm not sure how read in pair, first number represents process id , second amount of time takes before termination. want parseint string , grab each 1 separately before , after comma, or there easier way @ doing this. can't use arraylists either.

scanner fin = new scanner(new filereader(file));  while(fin.hasnext()){  int s = fin.nextint();

this have got far reading file in

is need?

scanner fin = new scanner(new filereader(file); string pattern = ","; fin.usedelimiter(pattern); while (fin.hasnext()) {     string s = fin.nextline();     string[] arr = s.split(pattern);     int processid = integer.parseint(arr[0]);     int time = integer.parseint(arr[1]); }

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
