can you give-me a little hand about java threads?

I have done this so far, but I am getting an error on main class

I believe its how to get the command (BufferedReader and StringTokenizer methods)

Please give me a hint. Code Below:
by the way, I have to create myshell with differents commands working in differents threads.

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.StringTokenizer;

public class MyShell
{
public static void main(String args[]) throws IOException
{
boolean exit = false;
while (!exit)
{

// Modification of txt into String
System.out.println("There is MyShell >>> ");
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

// Devide whole string into different sub-strings(tokens)
// and check if there is more tokens to read.
String input = in.readLine();
StringTokenizer token = new StringTokenizer(input, "&");

while(token.hasMoreTokens())
{
String[] command = new String[3];
command[0] = "cdm.exe";
command[1] = "/C";
command[2] = token.nextToken();

if(command[2].equals("exit"))
{
System.exit(0);
exit = true;
}

Runtime run = Runtime.getRuntime();
Process proc = run.exec(command);
thread_1 errorMessage = new thread_1(proc.getErrorStream(), "ERRORp");
thread_1 outputMessage = new thread_1(proc.getInputStream(), "Output ");
errorMessage.start();
outputMessage.start();
}
}
}
}

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

class thread_1 extends Thread
{

InputStream input;
String str;

thread_1(InputStream input, String str)
{
this.str = str;
this.input = input;
}

// Override run method
public void run()
{
try
{
InputStreamReader iReader = new InputStreamReader(input);
BufferedReader bReader = new BufferedReader(iReader);
String output = null;

while ((output = bReader.readLine())!= null)
System.out.println(str + ">>> " + output);

}
catch (IOException e)
{
e.printStackTrace();
}

}
}
