Write a program that determines the number of years it will take a home to double in value given the current value of the home and the predicted appreciation rate. Example A interleaved input and output with inputs 100000 and 0.042 Enter home value: 100000 Enter appreciation rate (3.8% enter as 0.038):0.042 It will take about 17 years to double in value. Example B interleaved input and output with an invalid input value: Enter home value: 10000000 Enter appreciation rate (3.8% enter as 0.038) : unknown Unexpected value: unknown

Algorithm For example, for a home valued at $100,000 and a predicted appreciation rate of 3.8%, we could start writing the code as: homeValue = 100000.0; years = 0; //after one year homeValue = homeValue + homeValue * 0.038; years++; //after two years home Value = homeValue +homeValue * 0.038; years++; //after three years homeValue = homeValue + homeValue * 0.038; years++; //... keep going until the home value doubles the initial value. What kind of loop would be most appropriate here? after 19 years the value is anticipated to be about $203,118, so it takes 19 years to double. Class HomeValue with two methods Create a class named HomeValue. Within the class write a method that has the current home value and predicted appreciation rate as parameters of type double and returns the number of years required to double in value. There should not be any input or output within this method. The method name should be a verb or verb phrase that describes what the method does and not how it is used. The main method prompts the user for the home value and predicted appreciation rate. With valid input values main calls the other method to calculate the number of years. Print out the resulting number of years in the main method. Error checking: Check if the user entered values can be converted to double values, if not then the program ends with the message "Unexpected value:" as shown in the example output.
