[a] create a class called âcycleâ which has two instance integer variables as properties, ânumberofwheelsâ and âweight.â create a constructor with two parameters, using the same variable names in the parameter list. assign each variable to numberofwheelsâ and âweightâ 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 constructorâs 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.
