Write a program to read test scores, process scores, and display a final report or save the report into a text file. A report is generated for a class of 4 students. Note: It is not required to write a Java class with instance/static members in this project. Write in method main. We will study how to write a Java class (chapter 6 and 8) in later lectures. A test score is an integer from 0 to 100. There are no extra credits. A letter grade can be assigned as follows: If an average is 90 or greater, the letter grade A is assigned. Otherwise, if an average is 80 or greater, the letter grade B is assigned. Otherwise, if an average is 70 or greater, the letter grade C is assigned. Otherwise, the letter grade F is assigned. Users can process the scores and display a report like this, save the report into a file, or quit
