Converting a class - InputStream to a String

Question

Hi. Very new to Java. I have the following class
import java.io.*;
class ShiftedInputStream extends InputStream
    ShiftedInputStream(InputStream source)
        source_ = source;
    public int read() throws IOException
        int bite = source_.read();
        if (bite != -1)
            bite >>>= 1;
        return bite;
    private InputStream source_;}
Currently being called as follows;
BufferedReader br = new BufferedReader( new InputStreamReader(new ShiftedInputStream(new FileInputStream( "/home/rich/cosworth/Logs/passwords.txt" )), "ASCII"));Rather than passing a file in (passwords.txt) I want to pass in a String. The problem I have is that I don't know the best way to do it. Do I
1) change the class ShiftedInputStream to accept a String, and if so how do I read a String bite by bite.
2) convert the String I want to pass in to an InputStream
3) something else completely.
Thanks for any help

I din get it still... But if ur talkin abt typecasting
Byte to string
string s = System.Text.Encoding.UTF8.GetString(bytes);String to byte
byte[] bytes = System.Text.Encoding.UTF8.GetBytes(s);
