Abstract class Pet has an array of Dose objects, as well as a subclass Dog
When I try to compile Dog.java, the first error i get (the problem I need the most help with) is:
Dog.java:5: cannot find symbol
symbol : constructor Pet()
location: class Pet
public class Dog extends Pet
^
I'm sorry if the answer can be found elsewhere in the forums, I've had a bit of a look, but havent seen (or at least recognised) the help i need
My code so far:
Pet.java:
CODE
public abstract class Pet
{
private String name;
private double weight;
private Date dob;
private double accumulatedDose;
public Pet(String nameIn, double weightIn, Date dobIn, double accumulatedDoseIn)
{
this.name = nameIn;
this.weight = weightIn;
this.dob = dobIn;
this.accumulatedDose = accumulatedDoseIn;
}
public abstract double getDose(double weight);
public int getAgeInMonths(Date d)
{
Date now = new Date();
int nowYear = now.getYear();
int nowMonth = now.getMonth();
int thenYear = d.getYear();
int thenMonth = d.getMonth();
int yearDiff = nowYear-thenYear;
int monthDiff = nowMonth-thenMonth;
int ageInMonths = yearDiff*12 + monthDiff;
return ageInMonths;
}
}
Dog.java:
CODE
public class Dog extends Pet
{
private String breed;
public double getDose(double weightIn)
{
int age;
Date dob = super.dob;
double doseInMilligrams;
age = super.getAgeInMonths(dob);
if (ageInMonths < 3)
doseInMilligrams = 0;
else if (ageInMonths > 12 && weight < 2)
doseInMilligrams = 6 + 0.75*weight;
else
doseInMilligrams = 12 + 0.65*weight;
}
}
and Dose.java:
CODE
public class Dose
{
private String nameOfDrug;
private Date date;
private double doseInGrams;
public Dose(String nameOfDrugIn, Date dateIn, double doseInGramsIn)
{
nameOfDrug = nameOfDrugIn;
date = dateIn;
doseInGrams = doseInGramsIn;
}
public double getDose()
{
return doseInGrams;
}
public Date getDate()
{
return date;
}
public String toString()
{
return nameOfDrug;
}
}
I realise that so far, most of my classes are incomplete, but any help and the pointing out of any mistakes so far would be appreciated.
Thanks
