A constructor that initializes the patient number. Methods to get and set each of these fields. A method double computeRatio() that divides LDL cholesterol by HDL cholesterol and returns the result. A toString() method that returns a string containing the values of all instance variables, as well as the result of computeRatio(), and a statement explaining that HDL is known as "good cholesterol" and that a ratio of 3.5 or lower is considered optimal.
