DogNode.shelter() [25 points]
This method takes as input a Dog object d and adds it to the tree that has as root the

In this assignment, you will modify your Quiz class from the previous assignment. You will
create a method that asks a quiz question and a method that checks the answer, and you will use
those methods to ask multiple questions. Your program will then report how many questions the
user got correct. This program will be the basis for future Programming Assignments in this
course.

Write a program to apply the package. The package is customer will consist classes of member and non-member.
Member:

- No discount

• Add a static method that asks a question until the user provides valid input.
• Call the method "ask". It should take a String parameter, and it should return a String.
static String ask(String question) {
• Remember where method definitions go: inside the class (in this case, "Quiz") but outside
all other method definitions (like "main"). It can go before or after the "main" definition.
• Ask the user the question repeatedly until the user provides a valid answer: "A", "B", "C",

• Ask the question using "JOptionPane.showInputDialog".
• Allow the user to provide a lower-case answer, and convert it to upper case.
• If the user provides an invalid answer, use "JOptionPane.showMessageDialog" to tell

Give an example of a while loop, then provide the equivalent do-while loop and for loop. Then give a different example of a do-while loop along with the equivalent while loop and for loop. Finally give an example of a for loop along with the equivalent while loop and do-while loop. Use your examples to illustrate the advantages and disadvantages of each looping structure and describe those disadvantages and advantages.
