Answer the following review questions from Lesson 9 by either typing directly into the textbox below or by uploading a document with your answers. Please include the question along with your answer to make your responses easy to read.

1. Explain the difference between a deep and a shallow copy.

2. 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.

3. There is a problem with the below mutator method. Correct the problem in twodifferent ways:

public void setAge(int age) {

age = age;

}

4. Pre-Midterm Practice: Write a complete class named Car. It has three private member variables make (String), model (String) and mileage (double). It has 3 constructors – a default constructor, a 3-argument constructor and a copy constructor. It has accessor and mutator methods for all variables. It has a toString() method.

Answer the following review question from Lesson 10 by either typing directly into the textbox below or by uploading a document with your answers. Please include the question along with your answer to make your responses easy to read.

1. Given the below class:

public class Dog {

private String name;

private double weight;

private static int numDogs = 0;

public Dog(String name, double weight) {

this.name = name;

this.weight = weight;

numDogs++;

}

public String getName() {

return name;

}

public double getWeight() {

return weight;

}

public static int getNumDogs() {

return numDogs;

}

public void printGreeting() {

System.out.println(“Woof!”);

}

@Override public String toString() {

return “Name: ” + name + “nWeight: ” + weight;

}

}

Add a method call to getNumDogs to the below starter code:

public class DogTest {

public static void main(String[] args) {

Dog fluffy = new Dog(“Fluffy”, 10);

Dog brutus = new Dog(“Brutus”, 100);

int num = //call getNumDogs method here!

}

}
