Consider the following class, which is intended to serve as a blueprint for objects that encapsulate two pieces of data: an even integer and a non-negative real number: public class ValuePair { int a; double b; public static double product() { return this. a * this. b; } } (2 points) The method product is supposed to be an instance method that returns the product of the two fields inside a ValuePair object. However, when we attempt to compile this class, we get error messages that indicate that product cannot access the fields. (Hint: What is another name for an instance method).

Acase study allows a more detailed look at the life of a single subject than any other study.

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.
