I need some help with a java application the idea is to create an application which is able to translate between back and forth between English – letters A-Z and numbers 0-9 – and Morse code – dots “.” and dashes “-“. The user will be prompted to enter something to translate. The user may enter either English or Morse code. The application will then analyze what the user entered to try and figure out if the user entered English or Morse code. If the analysis determines the user entered something in English, it will then translate it into Morse code. If the analysis determines the user entered something in Morse code, it will then translate it into English. At any time, the user may enter “-1” to exit the application.

HINT: Morse code is only dots “.” Dashes “-“ and spaces “ “. If the user input contains these 3 characters and only these 3 characters, it’s Morse code. Otherwise, assume it’s English.

Output:

Enter the string to conver to Morse Code (-1 to exit): hello
The morse code equivalent of hello is:
.... . .-.. .-.. ---

Enter the morse code to convert to String (-1 to exit)::.... . .-.. .-.. ---
The Equivalent String is :hello

Enter the string to conver to Morse Code (-1 to exit): bye
The morse code equivalent of bye is:
-... -.-- .

Enter the morse code to convert to String (-1 to exit)::-... -.-- .
The Equivalent String is :bye

Enter the string to conver to Morse Code (-1 to exit): -1
:: Program Exit ::
