Error in byte shifting a string

Question

Hi all
I am trying to set up a class that will byte shift a string. The class will accept an encrypted string as a parameter, calculate the decrypted version of this and then return it. It seems to be ding this correctly except it adda an extra character at the beginning of the string it returns.
For example it returns 'demo1' when it should just be 'demo1'.
I have the following so far
import java.io.*;
public class Decrypt {
    public Decrypt() {
    public String decryptPass(String encPass) {
        //Set blank decrypted pass to ""
        String decPass = "";
        try
            // loop through each char in encrypted pass, byte shiftin each char and
            // appending to the decrypted pass
            for( int i=0; i<encPass.length(); i++)
                int bt = encPass.charAt(i);
                if (bt != -1) {
                    bt >>>= 1;
                    decPass += (char)bt;
        catch (Exception e)
            e.printStackTrace();
        System.out.println("\t\t"+decPass);
        return decPass;
}Any ideas why this is would be appreciated.
Regards

Are you sure that the encrypted string is correct?
