Thank you

MIS276 JavaFX: Unit II Controls and Events Future Value Calculator Your lasK Using techniques from tonight's lecture program (FitTracker), recreate the Future Value of an Investment calculator. Here's the interface; a demo is also available on Canvas. Just download and extract the zip and then double-click the jar file to run. Future Value of an Investment Calculator Enter principal amount Enter expected rate of return (eg, 8 for 8%): Enter number of years money will be invested 1000 10 30 How frequently will the interest be compounded? AnnuallyMonthly Weedy Daly In 30 years, your initial investment of $1,000.00 will be worth $19 837 40 now. Future you will thank you. Clear Exit While I would like to see an identical layout to that shown in the demo, some minor variation in sizing and spacing is okay. For your reference, the money tree image in the demo is 340 pixels wide (ratio preserved). The buttons are each 150 x 50 pixels, and the results label ("In 30 years...") is 40 pixels in height. All other controls are default sized. Padding and gaps in the demo areall 10 or 20 pixels. You don't have to worry about error-proofing the user's input, but that would be a nice enhancement to this assignment!
