Create a class called Car that includes three instance variablesa model (typeString), a year (type String), and a price (double). Provide a constructor that initializes the threeinstance variables. Provide a set and a get method for each instance variable. If the price is not positive,do not set its value. Write a test application named CarApplication that demonstrates class Cars capabilities. Create two Car objects and display each objects price. Then apply a 5% discount on theprice of the first car and a 7% discount on the price of the second. Display each Cars price again.

A petrochemical plant in Island C produces formaldehyde (CH2O) industrially by thecatalytic oxidation of methanol (CH3OH). The following is the chemical reaction:CH3OH + O2 CH2O + H2O --- (1)Unfortunately, a significant portion of the formaldehyde will react with oxygen to produce COand H2O. The following is the side reaction:CH2O + O2 CO + H2O --- (2)Assume twice the stoichiometric amount of air needed for oxidation (all chemical reactions) isfed to the reactor. The conversion of methanol is 90% in the reactor. The outlet stream of thereactor was analysed and found to be 150 kg/hr of formaldehyde, 30 kg/hr of CO and othercomponents.(i) Determine the mass flowrate (kg/hr) of Stream A. (ii) Determine the molar flowrate (kg-moles/hr) of Stream B (iii) Determine the mass flowrate (kg/hr) of water in the outlet stream.
