Write a method convert that takes an argument arr that is an array for which you can assume every array element is an instance of a subclass of CoinCollection (don't worry about the array having nil elements). Implement convert so that it returns an array of procs, each of them taking an argument conversionRate, and returning the value of the corresponding CoinCollection given the specified conversionRate.

[a] create a class called “cycle” which has two instance integer variables as properties, “numberofwheels” and “weight.” create a constructor with two parameters, using the same variable names in the parameter list. assign each variable to numberofwheels” and “weight” respectively. write a separate application to test the class and display its properties. note: do not change the names of the instance variables or the variables listed in the constructor’s parameter list. [b] edit your class cycle by adding a default constructor which will assign the default values of 100 to represent the numberofwheels, and 1000 to represent the weight, by invoking a call to the other constructor. modify your application created in [a] to test the class.
