I'm taking a Java class and we have a assignment from the book working with strings and nothing I do seems to work, here's my code, copied from the book and still receive errors.
import javax.swing.JOptionPane;
public class DialogExample { public static void main(String[] args) { String annualInterestRateString = JOptionPane.showInputDialog( "Enter yearly interest rate, for example 8.25:"); double annualInterestRate = Double.parseDouble(annualInterestRateString); double monthlyInterestRate = annualInterestRate / 1200; String numberOfYearsString = JOptionPane.showInputDialog( "Enter number of years as an integer, \nfor example 5:"); int numberOfYears = Integer.parseInt(numberOfYearsString); String loanString = JOptionPane.showInputDialog( "Enter loan amount, for example 120000.95:"); double loanAmount = Double.parseDouble(loanString); double monthlyPayment = loanAmount * monthlyInterestRate / (1 – 1 / Math.pow(1 + monthlyInterestRate, numberOfYears * 12)); double totalPayment = monthlyPayment * numberOfYears * 12; monthlyPayment = (int)(monthlyPayment * 100) / 100.0; totalPayment = (int)(totalPayment * 100) / 100.0; String output = "The monthly payment is " + monthlyPayment + "\nThe total payment is " + totalPayment; JOptionPane.showMessageDialog(null, ); } } Help me Please!!
