JAVA for Eclipse
Objective:
The letters of the alphabet A through Z can be represented in Morse code. Each letter is represented by a combination of up to four dots and/or dashes, as shown below. Use Java to write and run a console-window program that can convert an English message into Morse code or a Morse code message into English. The program must satisfy the following requirements:
Description:
Create a class called MorseCode that at least has methods with the following signatures:
The MorseCode class will have two static variables:
Create a class AlphabetException. This class should extend Exception, and be used in case the user enters an invalid character in EITHER mode. For example, if the user wants to convert from English to Morse and enters a lower-case letter, your program should throw an AlphabetException.
Create a driver class called TestMorseCode. At a minimum
Example:
Morse Code Conversion Program.
