Problem with number of bits........

Question

Hello every one here........
I have a problem while converting a string of bits into characters...........my method is something like this......I am giving a string on client side....converting that string into string of bits and sending the bits to server side....now my problem is how to convert this string of bits into string which i originally gave at client side......
I used a method as shown below:
while(str.length()>0)
          i=7;
          System.out.print((char)Integer.parseInt(str.substring(0,i),2));
          str=str.substring(i);
here "str" is the string of bits which i received from client.......now coming to original problemEach character in the string which i gave on client side are converted to string of bits having 7 bits except the "space character" which is taking only 6 bits...... in my method as i am grouping 7 characters and printing the output i am getting wrong result after "space character"........
can anyone solve my problem.....
thanks in advance....

class BitStuff
     public static void main(String args[])
          try{
          String str=JOptionPane.showInputDialog("Enter ur code");
          char ch[]=str.toCharArray();
          String bitString="";
          String stuffedBits[]=new String[10000];     
          String stuffedString="";
          String counts;
/*here i am ensuring dat each character generates 7 bits*/
          for(int i=0;i<ch.length;i++)
               counts=(Integer.toBinaryString(ch));
               if(counts.length()<7)
                    for(int j=counts.length();j<7;j++)     
                    counts="0".concat(counts);
               bitString=bitString.concat(counts);
          String bitsArray[]=bitString.split("11111");
          for(int i=0;i<bitsArray.length;i++)
               stuffedBits[i]="111110".concat(bitsArray[i]);
               stuffedString=stuffedString.concat(stuffedBits[i]);
          stuffedString=stuffedString.replaceFirst("111110","");
          stuffedString="01111110".concat(stuffedString);
          stuffedString=stuffedString.concat("01111110");
          System.out.println(stuffedString);
          Socket s=new Socket("localhost",8280);
          OutputStream os=s.getOutputStream();
          byte b[]=stuffedString.getBytes();
          os.write(b,0,b.length);}
          catch(Exception e)
          {System.out.println(e);}
as the ascii of space is 32 it is 100000 here the method returns as 100000 instead of 0100000......
