1. Create a static method shorthand that receives a String and returns the String converted into shorthand.Do notuse the replace method to do this. The simplified shorthand form of a string is defined as follows (Note that these actions are done in sequence):
   1. Replace these four words: "AND" with "&", "TO" with "2", "YOU" with "U", and "FOR" with "4". The four words can be in mixed case (upper or lower or mixed).
   2. Remove all vowels ('a', 'e', 'i', 'o', 'u', whether lowercase or uppercase).
   Any repetition must be done using recursion (do not use loops). The string may be given in any case (lower or upper) or mixed case.
