Section 1 - Fundamentals

PalindromeEvaluator

• Description
  • The purpose of this class is to evaluator palindromes.
  • A palindrome is a word or phrase that is spelled the same forwards and backwards.
    • the word racecar is an example of a palindrome
• Methods to Complete
  • String reverseString(String str)
  • Boolean isPalindrome(String str)
  • String[] getAllPalindromes(String str)

StringEvaluator

• Description
  • The purpose of this class is to create a utility class for String
• Methods to Complete
  • String[] getAllSubstrings(String string)
  • String[] getCommonSubstrings(String string1, String string2)
  • String[] getLargestCommonSubstring(String string1, String string2)

Section 2 - Object Orientation

PalindromeObject

• Description
  • The purpose of this class is to create an object capable of evaluating palindromes.
• Methods to Complete
  • String reverseString()
  • Boolean isPalindrome()
  • String[] getAllPalindromes()

StringAssembler

• Description
  • The purpose of this class is to create a wrapper class for StringBuilder
• Methods to Complete
  • StringAssembler append(String string)
  • String append()

StringEvaluatorObject

• Description
  • The purpose of this class is to create a wrapper object for StringEvaluator
• Methods to Complete
  • String[] getAllSubstrings()
  • String[] getCommonSubstrings(String string2)
  • String[] getLargestCommonSubstring(String string2)

Section 3 - Collections

Student

• Description
  • The purpose of this class is to manage totalAmountOfHoursLearned
• Methods to Complete
  • void learn(Double amountOfHours)
  • Double getTotalStudyTime()

ZipCodeWilmington

• Description
  • The purpose of this class is to mediate List of Student objects.

  • Boolean has(String string)
  • String fetch(int indexOfValue)
  • void delete(String string)
  • void clear()

Section 4 - Generics

  • void push(T value)
  • T peek()
  • T pop()
  • Boolean isEmpty()

Group

• Description
  • The purpose of this class is to create a generic wrapper for a List object
• Methods to Complete

SortedGroup

• Description
  • The purpose of this class is to create a generic wrapper for sorted List object.
• Methods to Complete
  • insert(T value)
  • delete(T value)
  • Integer indexOf(T value)

GenericUtils

• Description
  • The purpose of this class is to create a procedure to generate the power set of an Set of objects.
• Methods to Complete
  • <T extends Comparable> Iterable<? extends Iterable<T>> powerSet(Set<T> originalSet)
  • <T extends Comparable> Iterable<? extends Iterable<T>> powerSet(T... originalSet)

ComparableTreeSet

• Description
