Question

This is the question -

Create a class named Apartment that holds an apartment number, number of bedrooms, number of baths, and rent amount. Create a constructor that accepts values for each data field. Also create a get method for each field.

Write an application that creates at least five Apartment objects. Then prompt a user to enter a minimum number of bedrooms required, a minimum number of baths required, and a maximum rent the user is willing to pay. Display data for all the Apartment objects that meet the user’s criteria or No apartments met your criteria if no such apartments are available.

This is the code I already have. It doesn't seem to like under TestApartments my apt. variable. I am unsure what to do to fix this cause it doesn't like any of my code -

public class Apartment {

int aptNumber;

int bedrooms;

double baths;

double rent;

public Apartment(int num, int bdrms, double bths, double rent) {

//write code here

aptNumber = num;

bedrooms = bdrms;

this.baths = bths;

this.rent = rent;

}

public int getAptNumber() {

return aptNumber;

}

public int getBedrooms() {

return bedrooms;

}

public double getBaths() {

return baths;

}

public double getRent() {

return rent;

}

import java.util.*;

public class TestApartments {

public static void main (String args[]) {

Scanner input = new Scanner(System.in);

Apartment apt1 = new Apartment(101, 2, 1, 725);

Apartment apt2 = new Apartment(102, 2, 1.5, 775);

Apartment apt3 = new Apartment(103, 3, 2, 870);

Apartment apt4 = new Apartment(104, 3, 2.5, 960);

Apartment apt5 = new Apartment(105, 3, 3, 1100);

int bdrms;

int baths;

double rent;

int count = 0;

System.out.print("Enter minimum number of bedrooms needed >> ");

bdrms = input.nextInt();

System.out.print("Enter minimum number of bathrooms needed >> ");

baths = input.nextInt();

System.out.print("Enter maximum rent willing to pay >> ");

rent = input.nextDouble();

System.out.println("\nApartments meeting citeria of\nat least " + bdrms + " bedrooms, at least " + baths + " baths, and " + " no more than $" + rent + " rent:");

//write your code here

boolean isExist = false;

for(int i=0; i<apts.length; i++){

if(checkApt(apts[i], bdrms, baths, rent)){

display(apts[i]);

isExist = true;

}

if(!isExist){

System.out.println("No apartments met your criteria");

}

public static boolean checkApt(Apartment apt, int bdrms, double baths, double rent) {

//write your code here

if(apt.getBedrooms()>=bdrms && apt.getBaths()>=baths && apt.rent<=rent)

return true;

return false;

}

public static void display(Apartment apt) {

System.out.println(" Apt #" + apt.getAptNumber() + " " + apt.getBedrooms() +

" bedrooms, and " + apt.getBaths() + " baths. Rent $" + apt.getRent());

}
