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;

}

}

a. 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.
