what host to set for RabbitMQ send test - rabbitmq

Question

So I am having trouble understanding how to use rabbitmq. I have the following Send.java class I am using RabbitMQ to send a message:
import com.rabbitmq.client.ConnectionFactory;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.Channel;
public class Send {
private final static String QUEUE_NAME = "hello";
public static void main(String[] argv) throws java.io.IOException {
// create a connection to the server
ConnectionFactory factory = new ConnectionFactory();
factory.setHost("WHAT DO I PUT HERE"); // <==========================What do I put here??
Connection connection = factory.newConnection();
// next we create a channel, which is where most of the API
// for getting things done resides
Channel channel = connection.createChannel();
// to send we must declare a queue for us to send to; then
// we can publish a message to the queue:
channel.queueDeclare(QUEUE_NAME, false, false, false, null);
String message = "Hello World!";
channel.basicPublish("", QUEUE_NAME, null, message.getBytes());
System.out.println(" [x] Sent '" + message + "'");
channel.close();
connection.close();
}
}
I don't really understand what I can set the host as to make this run as a Java application. Can someone explain? Thanks!

It's really self-explanatory... This method sets the default host to use for connection.
If you're using RabbitMQ on your local machine you can set it like this:
factory.setHost("localhost");
Or alternatively:
factory.setHost("127.0.0.1");
