android - Retrieving information from sqlite cursor -


i've make function search in db cursor column value. send string values search , function returns positions of rows have values. well, suppose work way. when run error in logcat:

java.lang.arrayindexoutofboundsexception: lenght=3; index=3

here function:

public string buscareceita(cursor c, string[] o) {       string info = "";     int f=0;     string pos= "";             int totalpos = c.getcount();      for(int y=0;y<totalpos;y++){         (string buscar : o) {             c.movetoposition(y);             info = c.getstring(c.getcolumnindex("idingredientes"));             string b[] = info.split("\\.");              for(int i=0; <= b.length; i++){                 if (b[i]==buscar){                     f++;                 }             }         }         if (f>=3) {             pos+=c.getstring(c.getposition())+".";                      }                 }     return pos;  }

in column "idingredientes" have formatted string like: 2.5.17. (this ids want). function suppose return ids if match minimal of 3 values.

sorry poor english guys, i'm brazil. grateful help!

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...
