# JAVA COMPILATION

A real estate office handles 50 apartment units.When the rent is \$600 per month, all the units are occupied. However, for each \$40 increase in rent, one unit becomes vacant. Each occupied unit requires an average of \$27 per month for maintenance. how many units should be rented to maximize the profit?

Write a program that prompts the user to enter:

a.The number of apartment untis

b.The rent to occupy all the units

c.The increase in rent that results in a vacant unit

d.Amount to maintain a rented unit

the program then outputs the number of units to be rented to maximize the profit.

Hi Friend,

Try the following code:

import java.util.*;

public class RealEstate{
public void findMaxProfit(int apartments,int rent,int increase,int maintenance){
int maxRent = 0;
int maxProfit = 0;
int maxApartments=0;
int notOccupied = 0;
int profit = 0;
System.out.println("Units Rent profit");
while(notOccupied<= apartments){
rent = rent + (notOccupied * increase);
profit= (apartments-notOccupied) *rent - (maintenance * notOccupied);
System.out.println((apartments-notOccupied) +" "+rent+" "+profit);

if(maxProfit < profit){
maxApartments = (apartments-notOccupied);
maxProfit = profit;
maxRent= rent;
}
notOccupied++;
}
System.out.println("Maximum Profit: "+maxProfit);
System.out.println("It occurs when Number of occupied Units is: "+maxApartments+" and rent is: "+maxRent);
}
public static void main(String args[]){
Scanner input=new Scanner(System.in);
System.out.print("Enter the number of apartment units: ");
int apartments = input.nextInt();
System.out.print("Enter the Rent value for all the occupied units: ");
int rent = input.nextInt();
System.out.print("Enter the increase in rent value: ");
int increase = input.nextInt();
System.out.print("Enter the Maintenance value for each occupied unit: ");
int maintenance = input.nextInt();

RealEstate.findMaxProfit(apartments,rent,increase,maintenance);
}
}

Thanks
