its short and easy

Part C: Write Java Code for the following case scenarios:

1. Look at the following partial class definition, and then respond to the questions that follow it:

public class Book

{

private String title;

private String author;

private String publisher;

private int copiesSold;

}

1. Write a constructor for this class. The constructor should accept an argument for each of the fields.
2. Write accessor and mutator methods for each of the fields.
3. Draw a UML diagram for the class, including the methods you have written.

2. Consider the following class declaration:

public class Addition

{

public int num1, num2;

public String s1;

public int add(int num1, int num2)

{

int sum = num1 +num2;

return sum;

}

}

1. Write a no argument constructor for the class. It should assign the value 0 to num1 and num2 fields.
2. Write an overload constructor for this class that will concatenate the string values passed as arguments to it.
3. Part C: Write Java Code for the following case scenarios:
4. Design a class named Pet, which should have the following fields:

• Name
• Animal
• Age

The Pet class should have following methods:

• setName
• setAnima
• setAge
• getName
• getAnimal
• getAge

1. Draw a UML diagram of the class. Be sure to include notation showing each field and method’s access specification and data type. Also include notation showing any method parameters and their data types.
2. Write the java code for Pet class.

3. . Consider the following class declaration:

public class Circle

{

private double radius;

public Circle (double r)

{

radius = r;

}

public double getArea()

{

return Math.PI * radius * radius;

}

public double getRadius()

{

return radius;

}

}

1. Write a toString method for this class. The method should return a string containing the radius and area of the circle.
2. Write an equals method for this class. The method should accept a Circle object as an argument. It should return true if the argument object contains the same data as the calling object, or false otherwise.
3. Write a greaterThan method for this class. The method should accept a Circle object as an argument. It should return true if the argument object has an area that is greater than the area of the calling object, or false otherwise.

4. Make a Land Tract class that has two fields: one for the tracts length and one for the width. The class should have a method that returns the tracts area, as well as the equals method and a toString Demonstrate the class in a program that asks the user to enter the dimensions for two tracts of land. The program should display the area of each tract of land and indicate whether the tracts are of equal size.
