Companies will occasionally list their phone number as text, rather than numbers, to make it easier for potential customers to remember. For example, '1-800-LAWYERS". Letters in the phone number String are mapped to digits like this:
ABC(2), DEF(3), GHI(4), JKL(5), MNO(6), PQRS(7), TUV(8), WXYZ(9)

Write a method that has a String parameter phone and returns a String containing the numerical equivalent for that phone number.
Convert phone to a char array and (in a loop) switch on the value of each character. I hope that you don't have 26 break statements in your program! Recall that cases without a break statement "fall" into the next case. Also, make use of the default case. Example program run (user input shown in red):
Enter phone String >>> 1-800-LAWYERS
Actual number >>> 1-800-529-9377 //use substring() to insert the last dash
