Explanation / Answer

The Car class implementation is as follows:

public class Car {
     private String Make;
     private int Year;
     private double Mileage;
     private double Cost;
     public Car(String mk, int yr, double ml, double cs){
          Make = mk;
          Year = yr;
          Mileage = ml;
          Cost = cs;
     }
     public void setMake(String s){
            Make = s;
     }
     public void setYear(int a){
            Year = a;
     }
     public void setMileage(double a){
            Mileage = a;
     }
     public void setCost(double a){
            Cost = a;
     }
     public String getMake(){
            return Make;
     }
     public int getYear(){
            return Year;
     }
     public double getMileage(){
            return Mileage;
     }
     public double getCost(){
            return Cost;
     }
     public void toString(){
          System.out.println(Make + " " + Year + " " + Mileage + " " + Cost);
     }
}

public class CarLot {
      private static final int NUM_CARS = 100;
      private Car[] lot;
      private static int numberOfCars = 0;    // Current size of the lot.Can not be more that MAX_CARS
      public CarLot(){
         lot = new Car[MAX_CARS];
        
      }
     
      public void addCar (Car a){
         if (numberOfCars == MAX_CARS)
            System.out.println("Lot is Full, can not add");
         if (numberOfCars < MAX_CARS){
             lot[lotsize] = a;
             lotsize++;  
         }
      }
      public ArrayList<Car> findMatchingCars(int year, String make){
          int i;
          ArrayList<Car> list = new ArrayList<Car>();
          for (i = 0; i<numberOfCars; i++){
              if (lot[i].getMake() == make && lot[i].getYear() == year)
                  list.add(lot[i]);
          }
          return list;
      }
      public void printMatchingCars(int year, String make){
          int i;
          for (i = 0; i<numberOfCars; i++){
              if (lot[i].getMake() == make && lot[i].getYear() == year)
                  lot[i].toString();
          }
           
      }
}
