Java Program ASAP ************This program must work in hypergrade and pass all the test cases.********** Please look closely at the underlined parts of the correct test case as shown in the screenshot. Observe the underline parts. Fix the program below so it outputs the correct test case and nothing else. It must print out that exact same output.

PC #14. Word Separator (modified *** Read carefully ***) Write a program that prompts the user to enter a file name, then opens the file in text mode and reads it line by line. While entering the file name, the program should allow the user to type quit to exit the program. If the file with a given name does not exist, then display a message and allow the user to re-enter the file name. The file can contain one or more sentences. The program should accept as input each sentence in which all the words are run together, but the first character of each word is uppercase. Convert sentences to strings in which the words are separated by spaces and only the first word starts with an uppercase letter. For example, the string StopAndSmellTheRoses.” would be converted to “Stop and smell the roses.” Sentences are separated by periods ('.'), exclamation marks ('!'), or question marks ('?'). Ensure that there is one space character in between sentences. text1.txt StopAndSmellTheRoses. text2.txt ATrueRebelYouAre!EveryoneWasImpressed.You'llDoWellToContinueInTheSameSpirit.
