Java - Issue with Classes and Methods

Question

I have been working on this application for a while, and I'm a bit frustrated but not ready to give up yet! I am having problems getting it to compile.

The errors I have been getting are below:

TestApartment.java:45: error: method isMatched in class TestApartment cannot be applied to given types;
 if(isMatched(apt1))
 ^
 required: Apartment,int,double,int
 found: Apartment
 reason: actual and formal argument lists differ in length
TestApartment.java:50: error: method isMatched in class TestApartment cannot be applied to given types;
 if(isMatched(apt2))
 ^
 required: Apartment,int,double,int
 found: Apartment
 reason: actual and formal argument lists differ in length
TestApartment.java:55: error: method isMatched in class TestApartment cannot be applied to given types;
 if(isMatched(apt3))
 ^
 required: Apartment,int,double,int
 found: Apartment
 reason: actual and formal argument lists differ in length
TestApartment.java:60: error: method isMatched in class TestApartment cannot be applied to given types;
 if(isMatched(apt4))
 ^
 required: Apartment,int,double,int
 found: Apartment
 reason: actual and formal argument lists differ in length
TestApartment.java:65: error: method isMatched in class TestApartment cannot be applied to given types;
 if(isMatched(apt5))
 ^
 required: Apartment,int,double,int
 found: Apartment
 reason: actual and formal argument lists differ in length

What do I need to do to get it to work?

public class Apartment
{ 
 int AptNumber;
 int numBedrooms;
 double numBathrooms;
 int AptRent;
public Apartment(int num, int beds, double baths, int rent)
{
}
public void setAptNumber(int num)// Accessor method for apartment number
{

{

{

 numBedrooms = beds;
}
public int getnumBedrooms() // Gets the number of bedrooms

}
 public void setnumBathrooms(double baths) // Gets the number of bathrooms
{

Answer 1

Your method public static boolean isMatched(Apartment apt, int bedrooms, double bathrooms, int rent) takes 4 parameters. How can you call it with 1 parameter then?

Call it like below:

if(isMatched(apt, bedrooms, bathrooms, rent))
