Please see the attached file.
that is the assignment.. Better to be done in plain Java and not fxml.. but if it can be done with fxml cheaper, I will take that too :)
Description Implement a compound interest calculator using JavaFX (see Fig. 1). The calculator should take the necessary information from the user: the principal ($), annual interest (%), compounding frequency (monthly, quarterly, semi-annually, or annually), and number of years. When the user clicks the Calculate button, the table view and bar chart should display the balance growth over the years (see a demo in the lecture on Oct 21). The formula to calculate a compound interest is as follows (https://en.wikipedia.org/wiki/Compound_interest): where: I is the interest P is the initial principal r is the annual interest rate n is the compounding frequency: 12 (monthly), 4 (quarterly), 2 (semi-annually), or 1(annually) t is the number of years For example: P = 1000, r = 5%, n = 1 (annually), t = 5 years Year Opening Interest Closing Interest calculation per year (t = 1) Balance Balance 1 1,000.00 50.00 1,050.00 1000 * (1 + 0.05)^1 – 1000 = 50.00 2 1,050.00 52.50 1,102.50 1050 * (1 + 0.05)^1 – 1050 = 52.50 3 1,102.50 55.13 1,157.63 … 4 1,157.63 57.88 1,215.51 … 5 1,215.51 60.78 1,276.29 1215.51 * (1 + 0.05)^1 – 1215.51 = 60.78 P = 1000, r = 5%, n = 2 (semi-annually), t = 5 years Year Opening Interest Closing Interest calculation per year (t = 1) Balance Balance 1 1,000.00 50.62 1,050.62 1000.00 * (1 + 0.025)^2 – 1000.00 = 50.62 2 1,050.62 53.19 1,103.81 1050.62 * (1 + 0.025)^2 – 1050.62 = 53.19 3 1,103.81 55.88 1,159.69 … 4 1,159.69 58.71 1,218.40 … 5 1,218.40 61.68 1,280.08 1218.40 * (1 + 0.025)^2 – 1218.40 = 61.68 Fig. 1: Compound interest calculator. Software Design (Qualities of Code) • There should be a separation of concerns in your software design – a main class that interacts with the user and other class(es) that perform the calculations and are reusable in other client applications. • Aim to write short and meaningful methods. • Avoid duplicated statements when possible. • Follow the Java naming conventions consistently and choose your variable, method, and class names well.
