Question

JAVA PROGRAM ASAP

The program down below does now work in hypergrade please modify it or create a new program  ASAP BECAUSE  it does not pass all the test cases when I upload it to hypergrade. I have provided the correct test case as well as the failed test case as a screenshot. It must pass all the test cases because it says 0 out of 2 passed when I upload it to Hypergrade. The program must pass the test case when uploaded to Hypergrade. Thank you

Chapter 9. PC #16. Morse Code Translator (modified *** Read carefully ***)
Morse code is a code where each letter of the English alphabet, each digit, and various punctuation characters are represented by a series of dots and dashes. Write a program that asks the user to enter a file name containing morse code, and then converts that code to text and prints it on the screen. The Morse code table is given in a text file morse.txt. When printing resulting text, display one sentence on each line. There should be no extra spaces at the beginning and at the end of the output.
