Create a class ArrayListUtils with the following (static) methods:

• removeDuplicates Removes duplicates from an ArrayList of Characters. The remaining character from the duplicates is always the first occurrence
  • params
    • data The ArrayList to remove duplicates from.
  • return An ArrayList with no duplicate entries remaining.
• getCommonStrings Finds the strings common to both given ArrayLists. If both lists contain the same entry multiple times, the resulting list should contain the entry exactly once.
  • params
    • list1 An ArrayList of Strings
    • list2 An ArrayList of Strings
  • return An ArrayList of Strings common to both list1 and list2
• wordRecall Reads in lines from a text file, then asks the user for a line number and a word number. Then, does one of the following:
  • If the number/word choice is invalid, displays an appropriate error message
  • If the user enters 'quit', exits the loop (but not the program)
  • Otherwise, prints the word at the given position
  • param
    • fname The name of the file to read in.

You are not allowed the use of any arrays, even if you do not directly create them. For example, the split method on strings returns an array, and therefore is not allowed.

    Enter a line number and a word number, separated by a space, or type 'quit' to quit.
