1. Write a program that generates a random
GlobalCredit using
GlobalCredit.getRandom().
Print each element of the collection by
using a loop to traverse the collection.
2. Write a program that generates a random
Portfolio using
Portfolio.getRandom().
Print each element of the collection by
using a loop to traverse the collection
using iterator-based traversal.
3. Write a program that generates a random
Portfolio using
Portfolio.getRandom().
Traverse the collection in reverse order
by using a regular for loop that counts
from the last index to the first index
and print each element of the traversal.
4. Write a program that generates a random
Student using
Student.getRandom().
Print each course taken by the student
along with the corresponding grade.
5. Write a program that generates a random
Student using
Student.getRandom().
Adjust each course grade up one letter grade
(ie. change F's to E's, E's to D's, D's to C's
and so on; obviously A's remain unchanged).
6. Write a program that takes one command
line argument (assumed to an integer
greater than or equal to zero).
Your program should generate a random
GlobalCredit using
GlobalCredit.getRandom().
Print each card in the collection on a separate line;
every card with a balance greater than the input amount
should be output with a '*' at the beginning
of the line.
7. Modify your solution to Question 6 so that every card with an available credit greater than the input amount is output with a '*' at the beginning of the line.
8. Write a program that takes one command
line argument (assumed to an integer
greater than or equal to zero).
Your program should generate a random
GlobalCredit using
GlobalCredit.getRandom().
Print each card in the collection with
a card number smaller than the input number
on a separate line. Then print the remaining
cards in the collection (one per line).
9. Write a program that generates a random
Portfolio using
Portfolio.getRandom().
Print each investment having
a stock whose name starts with a letter
in the range A-M on a separate line.
Then print the remaining investments
(one per line).
10. Write a program that generates a random
Student using
Student.getRandom().
Print every first year course taken
by the student and the corresponding course
grade (one per line). Then do the same
for all of the second year courses,
followed by all of the third year
courses, followed by all of the fourth
year courses.
11. Write a program that generates a random
Student using
Student.getRandom().
Find the minimum number of courses that
need to be retaken so that the GPA increases
by at least 1.0; assume that the student will
get an A for every course retaken. Output
the list of courses that need to be retaken.
[Note: it may not be possible to raise the
GPA by 1.0]
