Answer 1

Code MyProgram.java

import java.util.*;
public class MyProgram
{
        public static void main(String[] args) {
                Scanner sc = new Scanner(System.in);
                String add;
                double cost;
                //Ask for address and cost
                System.out.println("Enter Address :");
                add=sc.next();
                System.out.println("Enter Cost of House :");
                cost=sc.nextDouble();
                House obj=new House(add,cost);  
                System.out.println(obj.getString()+" "+obj.getmonthPayment());
        }
}

Code House.java:

import java.lang.Math;
public class House{
    private String address;
    private double cost;
    private double interst;
    private int mortgageTime;
    private double monthPayment;
    
    //Constructor
    public House(String address,double cost)
    {
        this.address=address;
        this.cost=cost;
        this.mortgageTime=20;
        this.interst=1.6;
    }
    //method to get monthly value
    public double getmonthPayment()
    {
        double down= (5*cost)/100;      //5% of cost
        double loan=cost-down;          
        this.monthPayment=(loan*interst/(100*12))/(1-Math.pow((1+((interst/(12*100)))),(-12*mortgageTime)));
        return monthPayment;
    }
    //method to get string
    public String getString()
    {
        return this.address;
    }
}

Sample Output:

Enter Address :
Pune
Enter Cost of House :
155000
Pune 717.3404427133927
