java - Converting binary to decimals and characters -

i want convert binary decimals , characters this:

11010 --> 1101 + 0(parity bit) -->decimals= 11 --> char ";" 10101 --> 1010 + 1             -->decimals= 5  --> char "5" . .  public class stringek {      string bitek = "1101010101001000001000001";     string[] bits;     string four;     char par;     int parity;     string digits;     int n = 0;     int b;     int kurens;     int decimalis;     int digit;      public stringek() {         this.kurens = 0;         bits = new string[200];         (int = 0; < 25; += 5) {             bits[n] = bitek.substring(i, + 5);             n++;         }         (int = 0; < n; ++i) {             int j = 0;             4 = bits[i].substring(j, j + 4);             (int p = 0; p < 4; ++p) {                 b = integer.parseint(four.substring(p));                 kurens += b;             }             par = bits[i].charat(j+4);             //system.out.print(par);             parity = par-'0';             decimalis = integer.parseint(four, 2);             digit = decimalis + 48;             if ((kurens + parity) % 2 == 0) {                 system.out.println("binarys: "+four+"-"+par+" = "+"'"+(char)digit+"'"+" decimalis:"+decimalis+"  parity <invalid>  ");             }             else{                 system.out.println("binarys: "+four+"-"+par+" = "+"'"+(char)digit+"'"+" decimalis:"+decimalis+"  parity <valid>  ");             }         }     }  } 

but program results this:

binarys: 1101-0 = '=' decimalis:13  parity <invalid>   binarys: 1010-1 = ':' decimalis:10  parity <valid>   binarys: 0010-0 = '2' decimalis:2  parity <invalid>   binarys: 0001-0 = '1' decimalis:1  parity <invalid>   binarys: 0000-1 = '0' decimalis:0  parity <valid> 

can me resolve? have cause in case parity valid, don't know why here parity invalid (i know cause results if give me results, want know how resolve valid when valid , invalid when invalid). thanks

public string[] splitstringevery(string s, int interval) {     int arraylength = (int) math.ceil(((s.length() / (double)interval)));     string[] result = new string[arraylength];      int j = 0;     int lastindex = result.length - 1;     (int = 0; < lastindex; i++) {         result[i] = s.substring(j, j + interval);         j += interval;     } //add last bit     result[lastindex] = s.substring(j);      return result; }
