Serialization via J2ME or BlackBerry APIs

Question

Is it possible to serialize an object into a string or a byte array using either the J2ME or BlackBerry APIs?

Thanks.

You are stuck with creating your own serialization process for your classes. It wouldn't be too difficult to create your own base class and then use somesort of reflection to automatically serialize your properties.

    ByteArrayOutputStream baos = new ByteArrayOutputStream();

    DataOutputStream outputStream = new DataOutputStream(baos);
    try {
        // serialize your object - 
        outputStream.writeInt(this.name);
        // Then push the player name.
        outputStream.writeUTF(this.timestamp);
    }
    catch (IOException ioe) {
        System.out.println(ioe);
        ioe.printStackTrace();
    }


// Extract the byte array
byte[] b = baos.toByteArray();
