Java hw help please


Question

Need help writing a code that reads a file, gathers the tokens, and then gives the user back an awnser based on the information from the tokens. In this case the tokens are names and test scores and the out puts are names and final grades. They are to all be displayed at once and it does not have to use any popup windows. Below are the teachers hw asignment and a piece of program he gave us to get started with

""Homework-2

You do not need to send me your input file. Your program should work with my input file named hw2.txt.

Write a java program FirstnameLastnameHw2.java that reads student info from an external file with the following data, and displays the grades as displayed below.

Input file hw2.txt (be aware of copy/paste issue). Add a record with your own name (and some numbers).

Max Batman 73 83 93 20 20 20 18

Jim Harper 76 88 68 15 20 20 20

Joanna Karr 62 92 91 12 20 20 18

Sue Hammond 75 88 78 20 0 20 20

Mickie Foxx 65 77 91 12 0 0 20

Sue Sirmons 98 52 94 20 20 20 0

Jacqueline Savannah 98 87 99 0 20 20 20

your name . . . .

There are three test scores, out of 100 each, worth 60% and four homework scores, out of 20 each, worth 40% of grade.

Apply 90%, 80%, 70% and 60% (standard) cutoff levels for letter grade computation.

Example output (grades/averages are not accurate):

Student Names Average Letter Grades

Batman, Max 87 B

Foxx, Mickie 53 F

Sirmons, Sue 93 A

while (inFile.hasNext())

I would read each line and each line use split string each space. This will return an array with first name, last name and grades in their own spot. Array[0] is first name. Array[1] last name etc. Then you can call a for loop on that array from 2 to array. Length. Then grab each grade and use parse into to return the intended value of that string. Then average the grade.

    • Well Statcounter doesn't count Edge users as Chrome. It uses the user agent and my understanding is the Brave browser users the standard Chrome user agent for privacy/tracking reasons and compatibility so that would help the Chrome numbers. Some Firefox users change the user agent for again compatibility reasons. I am going to totally guess the Chrome numbers are inflated some 5 or 6%.

    • Well duh. But it's not their agenda, they just push it forward.
    • Easier to move to Firefox, either Zen Browser or LibreWolf (which includes it by default)
