Java - Issue with Classes and Methods

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
{
    AptNumber = num;    
}

public int getAptNumber() // Gets the apartment number
{   
    return AptNumber;
}
public void setnumBedrooms(int beds) // Accessor method for bedrooms
{
    int numBedrooms;
    numBedrooms = beds;
}
public int getnumBedrooms()  // Gets the number of bedrooms
{
    return numBedrooms;
}
    public void setnumBathrooms(double baths) // Gets the number of bathrooms
{
    double numBathrooms;
    numBathrooms = baths;
    }

    return numBathrooms;

    AptRent = rent;

}
public void display(int num, int beds, double baths, int rent)
{

}
    public double display()
{
    return display();
}

}
