Challenges

Remember the rules for this are

• Try to use only the information given up to this point in this book.
• Try not to give up until you've given it a solid attempt

Challenge 1

Write a program that asks which Twilight character Bella should have ended up with.

It should keep asking this question until the user types the magic words "i do not care"

void main() {
    // CODE HERE
}

Challenge 2

Update the program above to also accept "I DO NOT CARE", "I Do Not Care", and any other mix of capital and lower-case letters

Challenge 3

Write a method called askForBirthday that asks for the year, month, and day that someone was born. This method should return all three pieces of information with a Birthday class.

class Birthday {
    // CODE HERE
}

Birthday askForBirthday() {
    // CODE ALSO HERE
}

void main() {
    Birthday b = askForBirthday();
    IO.println(b.year + "-" + b.month + "-" + b.day)
}

Challenge 4

Update the program above to reprompt the user if they enter any nonsensical information for the year, month, or day. This includes negative numbers for the year, month, or day.

Challenge 5

Update the birthday program to represent the month with an enum named Month.

Accept both the name of the month with any capitalization and the number of the month (starting with 1 for January) as valid ways to specify the month.

Make sure to still reprompt on unexpected inputs.

enum Month {
    JANUARY,
    FEBRUARY,
    MARCH,
    APRIL,
    MAY,
    JUNE,
    JULY,
    AUGUST,
    SEPTEMBER,
    NOVEMBER,
    DECEMBER
}

class Birthday {
    // CODE HERE
}

Birthday askForBirthday() {
    // CODE ALSO HERE
}

void main() {
    Birthday b = askForBirthday();
    IO.println(b.year + "-" + b.month + "-" + b.day)
}
