Thread: help me plss T_T

Make a program that will compute the monthly payment of a particular loan
- make a class named loan
- declare attributes amount loaned , duration , interest , total loaned and monthly payment
- declare setter and getter methods for amount loaned and duration
- create overloading constructor
- 1st constructor is a default
Constructor that assign 10000 to amount loan and 5 months for duration
- 2nd constructor accept single value for amount and assign 5 months for duration
- 3rd constructor accept 2 values for amount loan and duration
- Declare method getInterest that accept value for duration and return the interest based on the ff condition

Duration Interest
5months – 6months 2%
7months – 9months 3%
10 months – 12 months 4%

- Create method getTotalloan that accept values for amount loaned , interest and duration and contain compilation (amount loan*interest)*term

Create method getMonthlyPayment that receives value of total loan and duration , and will return the quotient of total loan/duration.

Make a class named Costumer w/ contain the main method
- Ask the user to input value for amount and duration and pass it into the constructor
Compute the interest , total loan , and monthly payment using method in loan class


use JoptionPane

Out put

[1] 1st constructor
[2] 2nd constructor
[3] 3rd constructor

Enter choice:
Amount loan:
Duration:
Interest:
Total loan:
Monthly Payment:

return (a*c)*b;}

public loan(double a,double b){
a = 10000;
b = 5;
}
}





import javax.swing.*;
public class costumer{
public static void main(String args[]){

int x = Integer.parseInt(JOptionPane.showInputDialog

if(x==1)
{
loan l = new loan(double a,double b);

l.setamtloan();
l.setduration();
l.setinterest();
l.settotalloan();
l.setmpayment();
l.getamtloan();
l.getduration();
l.getinterest();
l.gettotalloan();
l.getmpayment();
