<T> T[]toArray(T[] a) Returns an array containing all of the elements in this queue, in proper sequence; the runtime type of the returned array is that of the specified array. Methods inherited from class java.util.AbstractQueue
When you interact with queue using this Java client library, errors returned by the service correspond to the same HTTP status codes returned for REST API requests. For example, if you try to retrieve a queue that doesn't exist in your Storage Account, a 404 error is returned, indicating ...

The Java Message Service (JMS) specification, which Message Queue implements, supports two commonly used models of interaction between message clients and message brokers, sometimes known asmessaging domains: In thepoint-to-point(orPTP) messaging model, each message is delivered from a message produce...
