Does this Java code involving a `Book` class use proper encapsulation? I feel it can be a lot simpler if I omit some methods but we're required to every method that is in there [especially setters and getters].

Here's the first class:

```
public class Book
{
    private String title;
    private double price;
    private final double SALES_TAX=0.075;

    public String getTitle()
    {
        return title;
    }
    public void setTitle(String title)
    {
        this.title=title;
    }
    public double getPrice()
    {
        return price;
    }
    public void setPrice(double price)
    {
        this.price=price;
    }
    public double getSalesTax()
    {
        return SALES_TAX;
    }
    public double increasePrice(double incresePrice)
    {
        return incresePrice;
    }
    public double calculateSales(double sales)
    {
        return sales;
    }
}

```

And the second class:

```
public class BookDriver
{
    public static void main(String[] args)
    {
        Scanner keyboard=new Scanner(System.in);

        Book bookOne=new Book();
        Book bookTwo=new Book();

        bookOne.setTitle("Life of Pi");
        System.out.print("Enter number to buy of "+bookOne.getTitle()+": ");
        bookOne.setPrice(13.50*bookOne.calculateSales(keyboard.nextDouble()));
        bookOne.setPrice((bookOne.getPrice()*bookOne.getSalesTax())+bookOne.getPrice());
        System.out.print("Cost for "+bookOne.getTitle()+" $");
        System.out.printf("%.2f"+"\n",bookOne.getPrice());

        bookTwo.setTitle("Harry Potter: The Goblet Of Fire");
        System.out.print("Enter number to buy of "+bookTwo.getTitle()+": ");
        bookTwo.setPrice(22.00*bookTwo.calculateSales(keyboard.nextDouble()));
        bookTwo.setPrice((bookTwo.getPrice()*bookTwo.getSalesTax())+bookTwo.getPrice());
        System.out.print("Cost for "+bookTwo.getTitle()+" $");
        System.out.printf("%.2f"+"\n",bookTwo.getPrice());

        System.out.print("Enter percent increase of "+bookOne.getTitle()+": ");
        bookOne.setPrice((bookOne.getPrice()*bookOne.increasePrice(keyboard.nextDouble()))+bookOne.getPrice());
        System.out.printf("Cost of "+bookOne.getTitle()+": $"+"%.2f"+"\n",bookOne.getPrice());

        System.out.print("Enter percent increase of "+bookTwo.getTitle()+": ");
        bookTwo.setPrice((bookTwo.getPrice()*bookTwo.increasePrice(keyboard.nextDouble()))+bookTwo.getPrice());
        System.out.printf("Cost of "+bookTwo.getTitle()+": $"+"%.2f"+"\n",bookTwo.getPrice());

        keyboard.close();
    }
}

```

I know that this is a lot so I'm not really expecting much in terms of a response but anything would help. Thanks!!
