Write a program that calculates payments for loan system. Implement for both client and Server. - The client sends loan informat

ion to the server o annual interest rate o number of years o loan amount - The server computes monthly payment and total payment. - When the user presses the ‘Submit’ key, the server sends them back to the client. - Must use JavaFX - For computation follow the formulas below o monthlyInterestRate = annualInterestRate / 1200; o monthlyPayment = loanAmount * monthlyInterestRate / (1 - 1 / Math.pow(1 + monthlyInterestRate, numberOfYears * 12)); o totalPayment = monthlyPayment * numberOfYears * 12;
