Help With A Grading Program!!

[hjc]

i am trying to created a program that will write a grading program for a class with the following policies

there are 2 quizzes each graded on the basis of 10 points
there is 1 midterm and 1 final each graded on 100 points
the final exam counts for 50% of the grade, the midterm counts for 25% and the 2 quizzes togehter count for a total of 25%(i have to normailze the scores)

letter grades based on
90-100 A
80-89 B
70-79 C
60-69 D
0-59 E
the program will read in the student's scores from a text file, and output the students record which will have the names 2 quiz, and 2 exam as well as the student's average numeric score for the enitre course.(all scores are intergers )
i want to use standard I/O
the following is the code i have come up with
Class grade{
public static void main(String[] args){

double quiz1, quiz2, midterm, final, average;

Scanner grades = new Scanner(System. in);

while(grades.ha sNext())
{
quiz1 = grades.next();
quiz2 = grades.next();
midterm = grades.next();
final = grades.next();

if(quiz1 > 10 )
System.out.prin tln("ERROR quiz 1");
if(quiz2 > 10 )
System.out.prin tln("ERROR quiz 2");
if(midterm > 100 )
System.out.prin tln("ERROR midterm");
if(final > 100)
System.out.prin tln("ERROR final");


average = ( (midterm / 100) * .25 ) + ( ( quiz1/10 ) * .125 ) + ( ( quiz2/10 ) * .125 ) + ( ( final/100 ) * .50);


System.out.prin tln(" Quiz 1 score = " + quiz1 );

}

Read about how to read a file and correct your code then post and we'll see how far you will have got

thanks for the help-i am not understanding your question could you re word it

Did you read the comments in the code? I did not really ask a question but I asked you to read a tutorial on how to read files, re-write your code and post it then we work from there.

thanks i will and i will
