ID: 3554767 • Letter: T

Question

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:

Create a class called MorseCode that has at least the following two methods: (1) a method with signature toMorseCode(char) that accepts a single capital letter from the English alphabet and returns an array of 4 characters representing the Morse code equivalent of that letter, and (2) a method with signature fromMorseCode(char[4]) that accepts an array of four Morse code characters (each either a dot, a dash, or space) and returns the English letter equivalent. The MorseCode class will have two static variables. The first, of type char[], will store the 26 letters of the alphabet. The second, of type char[][], will store the Morse code for each of the 26 letters of the alphabet.

Create a driver class called TestMorseCode. At a minimum

Here is an example of its execution:

String answer2 = input.nextLine();

String dot = scan.nextLine();

for (int j=0; j < 26; ++j)
{
System.out.println( toAlpha( dot ));
