Question
Part a)
Create a class called MyDegree. It should have two variables of type double. One called fahrenheit and the other celsius. It should have one constructor that takes in two variables, the first of type double the second of type String. Depending on the value of the String parameter (which should be either fahrenheit or celsius) set the corresponding variable to the value passed as a parameter. Compute the value for the other variable. (Hint: Fahrenheit to Celsius: f = (9/5)*c +32, Celsius to Fahrenheit: c = (5/9)*(f-32). Create 2 get methods, one for each variable. Create 2 set methods, one for each variable (don
