JAVA PPROGRAM ASAP
Hypergrade does not like this program because it says 2 out of 7 passed and take out the extra \n from the program. Please Modify and change this program ASAP BECAUSE IT IS HOMEWORK ASSIGNMENT so it passes all the test cases. The program must pass the test case when uploaded to Hypergrade. Also, for test cases 1-4 it wants only to input Please enter the file name or type QUIT to exit: then input the file and display the Total number of words. For test cases 5 and 7 it wants to only to input Please enter the file name or type QUIT to exit then input input5.txt and then display File: input5.txt does not exist.\n then display Please enter the file name again or type QUIT to exit:\n then type input1.txt to display the total number of words or type quit to exit the program. For test case 6 it wants only to Please enter the file name again or type QUIT to exit:\n then type quit to exit the porgram.

In this exercise you will create a program that will be used in a digital library to format and sort journal entries based on the authors last name. Each entry has room to store only the last name of the author. Begin by removing the first name "Isaac" from the string variable journal_entry_1 by using the string function erase. Do not forget to also remove the whitespace so that the string variable journal_entry_1 will then contain the string "Newton" with no whitespaces. The journal entries should be sorted alphabetically based on the authors last name. For example, the last name "Brown" should come before the last name "Davis" Create an if statement so that if the last name contained within journal_entry_2 is alphabetically less than the last name contained within journal_entry_1, then the string values are swapped using the string function swap. You may use either of the comparison operators < > in the if statement but remember that following ASCII, "A" is…
