Completed:

ArithmeticMethods
Create an application named ArithmeticMethods whose main() method holds two integer variables.
Assign values to the variables. In turn, pass each value to methods named displayNumberPlus10(),
displayNumberPlus100(), and displayNumberPlus1000(). Create each method to perform the task
its name implies. Save the application as ArithmeticMethods.java.

ArithmeticMethods2
Modify the ArithmeticMethods class to accept the values of the two integers from a user at the keyboard.
Save the file as ArithmeticMethods2.java.

Painting
Create a class named Painting that contains fields for a painting’s title, artist, medium (such as water
color), price, and gallery commission. Create a constructor that initializes each field to an appropriate
default value, and create instance methods that get and set the fields for title, artist, medium, and price.
The gallery commission field cannot be set from outside the class; it is computed as 20 percent of the price
each time the price is set. Save the class as Painting.java.

TestPainting
Create a class named TestPainting whose main() method declares three Painting items. Create a method
that prompts the user for and accepts values for two of the Painting objects, and leave the third with the
default values supplied by the constructor. Then display each completed object. Finally, display a message
that explains the gallery commission rate. Save the application as TestPainting.java.
