In this type of sampling, you begin by identifying someone who meets the criteria for inclusion in your study. you then ask them to recommend others who they may know who also meet the criteria. although this method would hardly lead to representative samples, there are times when it may be the best method available. this type sampling is especially useful when you are trying to reach populations that are inaccessible or hard to find. for instance, if you are studying the homeless, you are not likely to be able to find good lists of homeless people within a specific geographical area. however, if you go to that area and identify one or two, you may find that they know very well who the other homeless people in their vicinity are and how you can find them. what sampling strategy is this?

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.
