Implement the following integer methods:

a)method celsius return the celsius equivalent of a fahrenheit temperature, using the calculation
celsius = 5.0/9.0*(fahrenheit -32);

b) method fahrenheit returns the fahrenheit equivalent of a celsius temperature, using the calculation
fahrenheit = 9.0/5.0*(celsius +32);

c)use the method from part (a) and (b) to write an application the enables the user either to enter a fahrenheit temperature and display the celsius equivalent or enter a celsius temperature and display the fahrenheit equivalent

Write a method that accepts a string object as an argument and returns the number of words it contains. for instance, if the argument is "four score and seven years ago", the method should return the number 6. demonstrate the method in a program that asks the user to input a string and then passes that string into the method, printing out whatever the method returns.

All of the following are characteristics that must be contained in any knowledge representation scheme except

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.
