You have just purchased a new Dell PowerEdge R820 Rack Server. The server is equipped with four Xeon E5-4650 CPUs, 128 GB of RAM, four 1 TB SAS hard drives, and two 750-watt power supplies. You have a 21-inch LCD monitor connected to your server. You want a UPS to keep your server running for up to 20 minutes in the event of a power failure. You prefer a rackmounted solution. Use the UPS selector tool at APC's Web site (a well-known UPS vendor). The UPS selector is at www. apcc. com/tools/ups_selector/. Determine which model of UPS will work well for this server, and state your reasons.

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.
