Java morse code to english and english to morse code translator

Morse code, developed in 1832 by Samuel Morse, is one of the most famous of all coding schemes ever developed. Morse code assigns a series of dots and dashes to each letter of the alphabet, each digit, and a few other punctuation characters. The international version of Morse code for alphabetic characters and digits is shown in the table below. Character code Character 4 5 6 03 ED 0 Thisproject ihes witing, progam to tandlat Mone code into tngih and tngh into Morse code. Your program shall prompt the user to specify the desired type of translation, input a string of Morse code characters or English characters, then display the translated results. The Morse code pattern and English letter translations must be kept and processed using either two one-dimensional or one two-dimensional arrays. When you input Morse code, separate each letter/digit with a single space, and delimit the sentence "to be". Your program only needs to handle a single sentence and can ignore punctuation symbols. When you input English, separate each word with a blank space.
