8.8 LAB: Course Grade
Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. Assume also the last names and first names do not contain whitespaces.
The program performs the following tasks:
Read the file name of the tsv file from the user.
Open the tsv file and read the student information.
Compute the average exam score of each student.
Assign a letter grade to each student based on the average exam score in the following scale:
A: 90 =< x
B: 80 =< x < 90
C: 70 =< x < 80
D: 60 =< x < 70
F: x < 60
Compute the average of each exam.
Output the last names, first names, exam…
a. The mean of a list of numbers is its arithmetic average. The median of a list is its middle value when the values are placed in order. For example, if a list contains 1, 4, 7, 8, and 10, then the mean is 6 and the median is 7. Write an application that allows you to enter five integers and displays the values, their mean, and their median. Save the files as MeanMedian.java.
b. Revise the MeanMedian class so that the user can enter any number of values up to 20. If the list has an even number of values, the median is the numeric average of the values in the two middle positions. Save the file as MeanMedian2.java.
JAVA PROGRAM ASAP
Please CREATE A program ASAP BECAUSE IT IS LAB ASSIGNMENT #2 so it passes all the test cases. The program must pass the test case when uploaded to Hypergrade.
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.
