output of console : {"result":[1572],"status":"ok"}

my question :

the value of bracked changing between 0 & 28800 , boolean. value 1 character (like[2]), 5 character (like[27924]), sometime [true] or [false].when run prg, need string value of bracked. how can ?

 while (true){         nextline =buff.readline();           if (nextline !=null){            system.out.println(nextline);               }         else break;          // added line , solved problem         system.out.println(nextline.substring((integer.valueof(nextline.indexof('[')) + 1),(integer.valueof(nextline.indexof(']')))));      } } catch(malformedurlexception e) { system.out.println("check url :" + e.tostring() ); }

output of console : {"result":[18627],"status":"ok"} 18627

thanks interest
