For this program, assume you have an input file with several lines of text. Each line has a student's last name, followed by a space and then 4 numbers which represent his/her grades. Your program should read this input file and produce an output file with the same number of lines, each line showing the last name and the average of the student's scores.
"grades.txt" is the file your program should read. "badformat.txt" is an example of a file that your program can't read, so a clear error message should be generated, as shown in the sample output.
Your program must catch all exceptions. Your main method must NOT have a "throws" clause - it must catch all exceptions and dea' with them appropriately. Other methods may throw exceptions, as long as the main method catches them.
I don't expect you to examine any filenames to make sure they're valid. Instead, you should use the filename the user gives you and try to open a file by that name. That will throw an exception if the filename is…
Your program should use a loop to read data from a text file which contains students' names and 3 exam scores. The program should calculate the exam average for each student, determine the appropriate letter grade for that exam average, and print the name, average, and letter grade. After printing all this, you need to print the count of the total number of A's, B's, C's, D's, and F's for the whole class.
The text file you need to use can be accessed using this link: scores.txt.
Copy this file to the folder where your program will reside. The text file contains a list of 30 records, and each record contains a name and that person's 3 test scores. Each field is separated by a tab character. The first 2 records looks like this:
Davis 88 92 84Wilson 98 80 73
and so on. Your program will need to open this file and read each line until the end of file. I recommend calculating a student's exam average and letter grade as you read the file, although this is not a…
Write a program that reads a file consisting of students’ test scores in the range 0–200. It should then determine the number of students having scores in each of the following ranges: 0–24,25–49,50–74, 75–99,100–124,125–149,150–174, and 175–200. Output the score ranges and the number of students. (Run your program with the following input data: 76,89,150,135,200,76,12,100,150,28,178,189,167,200,175,150,87,99,129,149,176,200,87,35,157,189.)
