Explain the answer step-by-step and include verbal explanation. Thank you!

Given the below classes:

public class Date {
   private String month;
   private String day;
   private String year;

   public Date(String month, String day, String year) {
      this.month = month;
      this.day = day;
      this.year = year;
   }

   public String getMonth() {
      return month;
   }

public String getDay() {
      return day;
   }

   public String getYear() {
      return year;
   }

   @Override public String toString() {
      return month + "/" + day + "/" + year;
   }
}

public class Dog {
    private String name;
    private double weight;
    private Date birthday;

    public Dog(String name, double weight, Date birthday) {
        this.name = name;
        this.weight = weight;
      this.birthday = birthday;
    }

    public String getName() {
        return name;
    }

    public double getWeight() {
     return weight;
    }

    public Date getBirthday() {
        return birthday;
    }

    public void printGreeting() {
        System.out.println("Woof!");
    }

    @Override public String toString() {
        return "Name: " + name
            + "\nWeight: " + weight
            + "\nDate: " + birthday.toString();
    }
}

Write a copy constructor for the above Dog class that creates a deep copy.

Expert Solution

Step 1

The deep copy of an object is done such that when changing the data members in the original object, the copied object would remain intact with its copied values and doesn't change with the original object values.

In Java, the deep copy of an object can be created using a copy constructor such that each property will be copied to the new object individually.
