java - select positions of value of string or int -

-

i'm trying select positions of value , print parts of value position in java when i'm working on android app. example if have number four-digit, 4375 if select 3rd 1 system print 7, 4th 1 system print 5..

you can select portion of string string.substring() methods. see https://docs.oracle.com/javase/7/docs/api/java/lang/string.html more help.

hence, convert digit string , use substring() method part want.

i provide solution suggestion:

    private string getsubdigit(int value, int postion){         // should check if value correct , ready processed.         if(check(value)) {            string temp = "" + value;            return temp.substring(position,position+1);         }else{            return "";         }       }
