Get the Message Type in JMS - IBM MQ

I am building an application which reveives message from a Message Queue , Process it and and send the generated response to another queue. I have successfully built the same.

But, before sending the msg I must get the Correlation ID, Message ID and Message Type from it, So that I will be able to set these in my generated response msg as well.

I have fetched CorrelationID and Message ID using the below code.

               Message Requestmessage = ReceiveMessage(queueName);
               String correlationID = Requestmessage.getJMSCorrelationID();
               String messageID = Requestmessage.getJMSMessageID();

How will I get the Message Type. There are 5 types of Messages as far as I understood. 1. Text Message 2. Byte Message 3. Stream Message 4. Object Message 5. Map Message All I need is, to find out which type my "Requestmessage" belongs to.

Thanks in Advance.

Found the answer. I used instanceof keyword.

        if(Requestmessage instanceof TextMessage )
        {
             //
        }

        if(Requestmessage instanceof BytesMessage)
        {
            //
        }
        if(Requestmessage instanceof ObjectMessage)
        {
            //          
        }
        if(Requestmessage instanceof StreamMessage)
        {
            //
        }
