I don't undertand why is this giving me Unhandled exception type ClassNotFoundException on command =  (String)dstObj.readObject(); ?

import java.io.IOException;
import java.io.InputStream;
import java.io.PipedOutputStream;
import java.io.ObjectInputStream;

public class Mystream implements Runnable {

      private InputStream in;
      
      public Mystream(PipedOutputStream srcPri, InputStream in)
      {

            this.in = in;
            
      }
      public void run()
      {
            try{
                  
                  ObjectInputStream dstObj = new ObjectInputStream(in);
                  
                  String command = null;
                  
                  //recieve a command
                  command =  (String)dstObj.readObject();
                  
                  //do something
                  System.out.print("TA doing something");
                  
            }catch(IOException e){
                  e.printStackTrace();
            }
            
      }
}

should be


     public void run()
     {
          try{
               
               ObjectInputStream dstObj = new ObjectInputStream(in);
               
               String command = null;
               
               //recieve a command
               command =  (String)dstObj.readObject();
               
               //do something
               System.out.print("TA doing something");
               
          }catch(IOException e){
               e.printStackTrace();
          }
            catch(ClassNotFoundException e) {
                e.printStackTrace();
            }
         
     }
