Thread: How to add buttons on this code

I am stuck with adding reset and exit buttons to this. Here is my code.

import java.text.DecimalFormat;
import javax.swing.JOptionPane;
 
public class MortgageCalculatorGUI///Name of my File and Class
{
public static void main(String[] args)
{
double loanAmount;//Declaring my Variables
double loanInterest;//Declaring my Variables
double monthlyPayment;//Declaring my Variables
double interestRate;
int loanTerm;
String totalLoan, interestLoan, termLoan;
DecimalFormat decimalPlaces=new DecimalFormat("0.00"); //Format decimal point for proper display
 
totalLoan=JOptionPane.showInputDialog(null, "Enter the Loan Amount: ");
loanAmount = Double.parseDouble(totalLoan);
 
interestLoan=JOptionPane.showInputDialog(null, "Enter the Interest Rate of the Loan in decimal Form: ");
loanInterest = Double.parseDouble(interestLoan)/12;
 
termLoan=JOptionPane.showInputDialog(null, "Enter the Term of the Loan: ");
loanTerm = Integer.parseInt(termLoan)*12;
 
 
// calculations
monthlyPayment = loanAmount *(loanInterest/(1 - Math.pow(1 + loanInterest, -loanTerm)));//Formula for Monthly Payments
 
JOptionPane.showMessageDialog(null,"Your Monthly Payments Are" + decimalPlaces.format(monthlyPayment));
System.exit(0);}}.

Can anyone help? It's for my homework assignment due Monday.

For future reference, please use the code tags. I don't know exactly what the question is....I suggest you read the following: How to Make Dialogs (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Swing Components)

import java.text.DecimalFormat;
import javax.swing.JOptionPane;
 
public class MortgageCalculatorGUI///Name of my File and Class
{
	public static void main(String[] args){
		double loanAmount;//Declaring my Variables
		double loanInterest;//Declaring my Variables
		double monthlyPayment;//Declaring my Variables
		double interestRate;
		int loanTerm;
		String totalLoan, interestLoan, termLoan;
		DecimalFormat decimalPlaces=new DecimalFormat("0.00"); //Format decimal point for proper display
 
		totalLoan=JOptionPane.showInputDialog(null, "Enter the Loan Amount: ");
		loanAmount = Double.parseDouble(totalLoan);
 
		interestLoan=JOptionPane.showInputDialog(null, "Enter the Interest Rate of the Loan in decimal Form: ");
		loanInterest = Double.parseDouble(interestLoan)/12;
 
		termLoan=JOptionPane.showInputDialog(null, "Enter the Term of the Loan: ");
		loanTerm = Integer.parseInt(termLoan)*12;
 
 
		// calculations
		monthlyPayment = loanAmount *(loanInterest/(1 - Math.pow(1 + loanInterest, -loanTerm)));//Formula for Monthly Payments
 
		JOptionPane.showMessageDialog(null,"Your Monthly Payments Are" + decimalPlaces.format(monthlyPayment));
	}
}

Where you want to add button my dear?
