Object (which has non-serializable attr.) serialization

Question

i could not solve object serialization problem in anyway. how can this be performed without "java.io.NotSerializableException"?
import java.awt.Image;
import java.awt.Toolkit;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectOutputStream;
import java.io.Serializable;
public class Object2ByteArray {
    public static void main(String[] args) {
        Object2ByteArray obj2ba = new Object2ByteArray();
        AnObject anObj = obj2ba.new AnObject();
        try {
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            //FileOutputStream fos = new FileOutputStream("C:\\obj.file");
            ObjectOutputStream oos = new ObjectOutputStream(baos); //or (fos)
            baos.writeTo(oos);
            oos.writeObject(anObj);
            oos.flush();
            byte[] objInBytes = baos.toByteArray();
            System.out.println("An object (which has a non-serializable element[Image]) is written to ObjectOutputStream.");
        } catch (IOException e) {
            e.printStackTrace();
    public class AnObject implements Serializable {
        Image img = Toolkit.getDefaultToolkit().getImage("C:\\anil.jpg");
        int c = 10;
        String desc = null;
}

Hi,
No, transient means that the attribute won't be sent over the stream. You usually declare fields that you don't want to send, or can't send as transient.
