Hvordan sætter jeg en klasse ind?

Jeg er ved at lave en MIDlet, og vil bruge RMS.
Til det har jeg fundet følgende klasse hvorfra jeg kan bruge RMS:

import java.io.*;
import javax.microedition.rms.*;

public class Record implements DataInput {

    private RecordStore _rs;
    private byte[] _data;
    private int _length;
    private int _id;
    private DataInputStream _din;

    public Record( RecordStore rs ){
        this( rs, 100 );
    }

    public Record(
              RecordStore rs, int initialRecordSize ){
        _rs    = rs;
        _data  = new byte[ initialRecordSize ];
        _din    = new DataInputStream(
                  new ByteArrayInputStream( _data ) );
        _length = -1;
    }

    public byte[] getByteArray() { return _data; }

    public int getLength() { return _length; }

    public byte[] moveTo( int id )
                throws RecordStoreNotOpenException,
                              InvalidRecordIDException,
                                  RecordStoreException,
                                          IOException
    {
        _length = _rs.getRecordSize( id );

        if( _length > _data.length ){
            _data = new byte[ _length + 40 ];
            _din  = new DataInputStream(
                  new ByteArrayInputStream( _data ) );
        }

        _rs.getRecord( id, _data, 0 );
        _id = id;
        _din.reset();

        return _data;
    }

    public void readFully(byte b[])
                                  throws IOException {
        _din.readFully( b );
    }

    public void readFully(byte b[], int off, int len)
                                  throws IOException {
        _din.readFully( b, off, len );
    }
      return _din.skipBytes( n );
    }

    public boolean readBoolean() throws IOException {
        return _din.readBoolean();
    }

    public byte readByte() throws IOException {
        return _din.readByte();
    }

    public int readUnsignedByte()
                                  throws IOException {
      return _din.readUnsignedByte();
    }

    public short readShort() throws IOException {
        return _din.readShort();
    }

    public int readUnsignedShort()
                                  throws IOException {
      return _din.readUnsignedShort();
    }

    public char readChar() throws IOException {
        return _din.readChar();
    }
    public int readInt() throws IOException {
        return _din.readInt();
    }

    public long readLong() throws IOException {
        return _din.readLong();
    }

    public String readUTF() throws IOException {
        return _din.readUTF();
    }
}

Problemet er bare, at den hele tiden melder tilbage 'class' or 'interface' expected.

Det project jeg arbejder ud fra er

import java.io.*;
import javax.microedition.rms.*;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;

public class TestStore
    extends MIDlet
    implements CommandListener

{



  private Form mMainForm;

  public TestStore()
  {
    mMainForm = new Form("Min første MIDlet");
    mMainForm.append(new StringItem(null, "hello world"));
    mMainForm.addCommand(new Command("Afslut", Command.EXIT, 0));
    mMainForm.setCommandListener(this);
  }


  public void startApp()
  {
    Display.getDisplay(this).setCurrent(mMainForm);
  }

  public void pauseApp() {}

  public void destroyApp(boolean unconditional) {}

  public void commandAction(Command c, Displayable s)
  {
    notifyDestroyed();
  }

}

Hvordan får jeg klassen sat ind i mit projekt?
