Customers might want their shipments to be delivered very urgently,in which case the priority of shipments comes into role. For those kinds of emergency shipments, the shipment detail will have an additional attribute to say if it is a priority shipment or not. While unloading the containers, the priority shipments are to be sent out first than the other. Writ a program using the concept of priority queue to display a list which depicts the order in which shipments are sent out if there are priority shipments.Creat a class Shipment with the following private member variables/attributes. 
String name 
String arrivalPort 
String departurePort 
Integer priority
Include a default constructor and 4-argument constructor with following argument order name, arrivalPort, departurePort, priority
Include appropriate getters and setters. Override compareTo method by implementing Comparable interface.
Creat a class Main to test above classes.
