write a method

strToList()

public static ArrayList strToList(String word)

This method transforms a String into an ArrayList containing each character of the string in order.

For example, strToWord("word") will return an ArrayList of four characters: {w,o,r,d} .

strToWord("hello CSE8B") will return an

ArrayList: {h,e,l,l,o, ,C,S,E,8,B}

• Return an empty list if the string is empty.
• Return null if the string is null
• Think about base case.
  • When should the method terminate/end?
  • Under what condition should your method stop making recursive calls and return your expected value?
• Think about the recursive case
  • Make recursive calls to the method; make sure to call to strToList
    • How would the input have to change in the recursive call?
    • Keep in mind, you do not need to keep the original ArrayList content.
• An iterative solution will not be accepted.
