Question

answer in JAVA language please

In this assignment you will use: one-dimensional arrays; strings and various string-handling methods; file input and output; console input and output; loops; and conditional program statements.

Instruction

You are asked to write a program that translates a Morse code message into English language. The program will ask the user to enter filenames for two input files, one for the code translation table data and the other for the coded message data, as well as an output file that will receive the decoded message text. Initially the program reads the code translation table data file and stores the alphabet characters and equivalent Morse code in two one-dimensional arrays. The program will then read the message input file, inspecting each Morse code value and converting it to the English-language equivalent. The program will write decoded words to the output file and will print short informational messages to the console (screen).

Morse code words in the message input file have one space between each Morse-coded letter. There is ONE word per line in the data file.

Code Translation Table:

Character Code

1. A .-

2. B -...

3. C -.-.

4. D -..

5. E .

6. F ..-.

7. G --.

8. H ....

9. I ..

10. J .---

11. K -.-

12. L .-..

13. M --

14. N -.

15. O ---

16. P .--.

17. Q --.-

18. R .-.

19. S ...

Assignment #3 Morse Code Translation

Test Plan

Given the input file CodedMessage.txt containing: - .... .. ...

.. ...

.-
- . ... -
.--. .-. --- --. .-. .- -- .-.-.- .. ..-.

Here is a sample run. User input appears as bold underline:
Enter Morse Code translation table file path: c:/temp/morse.txt

Code translation file processed. 39 codes loaded.

Enter coded message input file path: c:/temp/CodedMessage.txt Enter decoded message output file path: c:/temp/DecodedMessage.txt Message translation complete. 17 words processed.

Here is the output file DecodedMessage.txt contents:

THIS IS A TEST PROGRAM.
IF YOU SEE THIS MESSAGE THAT IS GOOD NEWS YOUR PROGRAM WORKS.
