3.1 Print Array
Write a method that prints out a string array, one element per line
3.1.1 Example
1: String [] breakfast = {"Sausage", "Eggs", "Beans", "Bacon", "Tomatoes", "Mushrooms"}; 2: 3: printArray(breakfast) 4: *** Output *** 5: Sausage 6: Eggs 7: Beans 8: Bacon 9: Tomatoes 10: Mushrooms
3.2 Last Element of Array
Write a method that returns the last element of a string array
3.2.1 Example
1: String [] breakfast = {"Sausage", "Eggs", "Beans", "Bacon", "Tomatoes", "Mushrooms"} 2: 3: System.out.println(lastElement(breakfast)); 4: *** Output *** 5: Mushrooms
3.3 Last But One Element of Array
Write a method that returns the last but one element of a string array
3.3.1 Example
1: String [] breakfast = {"Sausage", "Eggs", "Beans", "Bacon", "Tomatoes", "Mushrooms"} 2: 3: System.out.println(lastButOne(breakfast)); 4: *** Output *** 5: Tomatoes
3.4 Reverse an Array
Write a method that reverses the elements of an Array
3.4.1 Example
1: String [] breakfast = {"Sausage", "Eggs", "Beans", "Bacon", "Tomatoes", "Mushrooms"}; 2: 3: System.out.println(reverse(breakfast)); 4: *** Output *** 5: : Mushrooms 6: : Tomatoes 7: : Bacon 8: : Beans 9: : Eggs 10: : Sausage 11: : Tails
3.5 Palindromic Arrays
Write a method that tests to see if an array is palindromic, i.e. the elements are the same when reversed.
3.5.1 Example
1: String [] palindromic = {"Sausage", "Eggs", "Beans", "Beans", "Eggs", "Sausage"}; 2: String [] breakfast = {"Sausage", "Eggs", "Beans", "Bacon", "Tomatoes", "Mushrooms"} 3: 4: System.out.println(isPalindrome(palindromic)); 5: System.out.println(isPalindrome(breakfast)); 6: *** Output *** 7: True 8: False
3.6 Consecutive Duplicates
Write a method to print out an int array with consecutive duplicates eliminated
1: int [] nums = {1,1,3,3,3,2,2,2,1,1,1,1,4,4,4,4}; 2: 3: compress(nums) 4: *** Output *** 5: : 1 6: : 3 7: : 2 8: : 1 9: : 4 10: : 1 11: : 1 12:
3.7 Pack Duplicates
Pack consecutive duplicates of a char array into Strings
1: char [] letters = {'a' 'a' 'a' 'a' 'b' 'c' 'c' 'a' 'a' 'd' 'e' 'e' 'e' 'e'}; 2: 3: pack(nums) 4: *** Output *** 5: : aaaa, b, cc, aa, d, eeee 6:
