Cannot run command window

In Windows I would expect to call up a seperate command window with the following, but it appears to freeze up. What am I doing wrong?

import java.io.*;

publicclass command{

publicstaticvoid main(String[]args){

try{

Process runprogram = Runtime.getRuntime().exec("C:\\windows\\system32\\cmd.exe");

try{

runprogram.waitFor();

}

catch(InterruptedException e){}

}

catch(IOException e){

System.err.println("Cannot run command window");

}

}

}
