Question

This is Java language:

Part II: Can You Hear Me Now? (5 points) Filename(s): Homework5Methods. java Write a method public static String getDigits (String phoneNumber) that takes an 11-character phone number written with any combination of 11 uppercase letters, lowercase letters and/or digits, and zero or more hyphens, and which returns the digits that a person would have to press on a cell phone to dial that phone number. We will use the mapping of letters to digits given at en . wikipedia. org/wiki /Telephone-keypad# /media/File:Telephone-keypad2.svg You may assume that the String parameter phoneNumber contains some combination of exactly 11 uppercase letters, lowercase letters and/or digits, but that any number of hyphens may be present. You can assume that a hyphen will not appear as the first or last character of the string. Do not assume that the first character is always a 1. Examples: Return Value Method Call getDigits ("1-800-Flowers")"18003569377" getDigits ("1800FLOWERS"18003569377" getDigits ("1-CSE-114-JAVA")"12731145282" getDigits ("Seawolf-SBU-1") 73296537281"
