                     price = in.readInt();
                     book= in.readUTF();
                     System.out.format(" %s  %d%n",book, price);
                    
                     //if (in == -1)
                          //eof = true;

          }
       }
      catch (EOFException e) {

                e.printStackTrace();
      }

    }
   }

The error is no main class!

Why?

Check out the signature of your main method:

public void main(String[] args) throws IOException

Isn't there something missing?
