Suppose within your web browser you click on a link to obtain a web page. the ip address for the associated url is not cached in your local host, so a dns lookup is necessary to obtain the ip address. suppose that n dns servers are visited before your host receives the ip address from dns; the successive visits incur an rtt of rtt1, …, rttn. further suppose that the web page associated with the link contains exactly one object, consisting of a small amount of html text. let rtts denote the rtt between the local host and the server containing the object. assume that the transmission time of the object is ti. how much time elapses from when the client clicks on the link until the client receives the object

Write a car class having two private member variables called tank and speed. write public methods called pumpgas and gofast. the method pumpgas gets an integer for gas that must be pumped. that value needs to be added to tank (no more than 20 gallons). it must return the amount of gas that is purchased ($4 per gallon). the method gofast should increase the speed by 5 each time it is called.write a constructor for the above class that initialized both variables to zero.write a tostring to display both the tank and speed when the car is printed.modify the car class to implement the interface comparable and an interface called carinter having the public methods in carinter.write the main program to create an array of size 5 of type car. create 5 car objects having each location of the array to refer to one of the cars. test the pumpgas, gofast, equals method on the array items. write an enhanced loop to print all the car values (using a tostring written last time).write a generic method to find the minimum of four items. pass int, double, char, string and car objects to test this method.
