How to get Messages by the consumer according to priority of the messages set by the publishers RabbitMQ - rabbitmq

Question

I have publish messages with some priority set for a single consumer(i.e single consumer that may receive messages according to message priority).
What i want is to get that messages and print them according to the message priority on the consumer side. Hey guys Help me out in this !
public class Send extends Thread {
int priority;
String name = "";
String app_type = "";
private static final String EXCHANGE_NAME = "topic_exchange";
public void run()
{
ConnectionFactory connFac = new ConnectionFactory();
connFac.setHost("localhost");
try {
Connection conn = connFac.newConnection();
Channel channel = conn.createChannel();
channel.exchangeDeclare(EXCHANGE_NAME,
BuiltinExchangeType.TOPIC);
for(int j=1; j<=200; j++)
{
randomWait();
int random = (int)(Math.random() * 10 + 1);
String routingKey = j+"."+"update"+"."+app_type;
String msg = name;
channel.basicPublish(EXCHANGE_NAME, routingKey, new
AMQP.BasicProperties.Builder()
.contentType("text/plain")
.deliveryMode(2)
.priority(priority)
.build(),
msg.getBytes("UTF-8"));
System.out.println("Sent " + routingKey + " : " + msg +
" "+" Priority : "+priority);
}
channel.close();
conn.close();
} catch (IOException ex) {
Logger.getLogger(Send.class.getName()).log(Level.SEVERE, null,
ex);
System.out.println("Exception1 :--"+ex);
} catch (TimeoutException ex) {
Logger.getLogger(Send.class.getName()).log(Level.SEVERE, null,
ex);
System.out.println("Exception 2:--"+ex);
}
}
void randomWait()
{
try {
Thread.currentThread().sleep((long)(200*Math.random()));
} catch (InterruptedException x) {
System.out.println("Interrupted!");
}
}
public static void main(String[] args) {
// TODO code application logic here
Send test1 = new Send();
test1.name = "Hello ANDROID";
test1.app_type = "ANDROID";
test1.priority = 10;
Send test2 = new Send();
test2.name = "Hello ANDROID";
test2.app_type = "ANDROID";
test2.priority = 5;
test1.start();
test2.start();
}
}
In the above code I have use thread to pass the priority and message value and started the both the thread at the same time to publish messages with different priorities. I have set the priority value in the AMQ Builder.

The queue has to be configured to support priority.
