what host to set for RabbitMQ send test -

-

so having trouble understanding how use rabbitmq. have following send.java class using rabbitmq send 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 connection server         connectionfactory factory = new connectionfactory();         factory.sethost("what put here"); // <==========================what put here??         connection connection = factory.newconnection();         // next create channel, of api         // getting things done resides         channel channel = connection.createchannel();          // send must declare queue send to;         // can publish message 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 understand can set host make run java application. can explain? thanks!

it's self-explanatory... method sets default host use connection. if you're using rabbitmq on local machine can set this:

factory.sethost("localhost");

or alternatively:

factory.sethost("127.0.0.1");

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()
