    Default New to Java. Need help with homework

    I am having a hard time starting this project I am suppose to write a program that reads a text file and then takes the tokens from the text file and and in this case gives the user back a name a number grade and a letter grade. Please help im stuck

    ""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

    Harper, Jim 73 C

    Karr, Joanna 78 C

    Hammond, Sue 82 B

    Foxx, Mickie 53 F

    Sirmons, Sue 93 A

    Savannah, Jacqueline 94 A

    Your name .. ..

    { public static void main(String[] args) throws Exception
    { File file1 = new File("hw2.txt"); // finds file
    Scanner inFile = new Scanner(file1); // reads file
    // Scanner keyboard = new Scanner(System.in) allows for changes

    while (inFile.hasNext())

    where to go from here
    What's next?
    Make a list of the things the program needs to do. Check off the ones you have done so far, and start working on the next item in the list.

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
