Error in MIDlet

Question

i am trying to create a midlet that gets the BTSPP of the connected device, here's the code
import javax.microedition.io.*;
import javax.bluetooth.BluetoothStateException;
import javax.bluetooth.DataElement;
import javax.bluetooth.DeviceClass;
import javax.bluetooth.DiscoveryAgent;
import javax.bluetooth.DiscoveryListener;
import javax.bluetooth.LocalDevice;
import javax.bluetooth.RemoteDevice;
import javax.bluetooth.ServiceRecord;
import javax.bluetooth.UUID;
public final class BTMIDlet extends MIDlet
     public void startApp()
          // set the port number
          BCC.setPortNumber("COM12");
          // set the baud rate
          BCC.setBaudRate(9600);
          // set the connectable mode
          BCC.setConnectable(true);
          // set the discovery mode to Limited Inquiry Access Code
          BCC.setDiscoverable(DiscoveryAgent.LIAC);
          // retrieve the device that is at the other end of
          // the Bluetooth Serial Port Profile connection,
          // L2CAP connection, or OBEX over RFCOMM connection
          RemoteDevice remote = RemoteDevice.getRemoteDevice(javax.microedition.io.Connection c);
          // retrieve the Bluetooth address of the remote device
          String remoteAddress = remote.getBluetoothAddress();
          // retrieve the name of the remote Bluetooth device
          String remoteName = local.getFriendlyName(true)
but i m getting the msg that io variable doesn't exist. now wat shud i do??

I modified the code anew the track where to code is going.
          int a = MainDisplay.size()-1; 
          // this line will print the size of the form - 1
          System.out.println(a);
          display.setCurrent(procCategory);
          for (int i=a; i>=0; i--){
          // this line will print the current item being deleted.
              System.out.println(i);
              MainDisplay.delete(i);
          }Here's the output of the console window.

I uploaded the said file again to my phone but I also got the same error. It says application error and so so the application needs to be closed. I've tried every method but it seems like it can't be debugged. could this be really a KVM problem? I don't see any error in the code I am making.
By the way, MainDisplay is of type form (User Interface). the delete(i) is a method for forms deleting the item indexed by i. All the items appended in a form is indexed from 0 to size()-1, where size() is also a method indicating the number of elements being appended to it.
