Question

Write a program that reads a students name together with his orher test scores. The program should then compute the average testscore each student and assign the appropriate grade. The programshould then compute the average test score for each student andassign the appropriate grade. The grade scale is as follows:

90-100, A; 80-89, B; 79-70, C; 60-69, D; 0-59, F.

Your program must use the following methods:

·      A void method,calculateAverage,to determine the average of five test scores for each student. Usea loop to read and sum the five test scores. (This method does notoutput the average test score. That talk must be done in the methodmain.

·      A value-returning method,calculateGrade, todetermine and return each students grade. (This method doesnot output the grade. That task must be done in the methodmain.

Test your program on the following data. Read the data from afile and send the output to a file. Do not use any globalvariables. Use the approximate parameters to pass values in and outof methods.

The first part of the plansays:

Get reference to inputsource

Get reference to outputdestination

How does one do that first part?Thanks for any help.

Explanation / Answer

please rate - thanks import java.util.*; import java.io.*; public class Malik714 {static double average=0; public static void main(String[] args)throwsFileNotFoundException {int[] test=new int[5]; int i; char grade; String filename,name; Scanner in = new Scanner(System.in); System.out.println("Enter name of input file"); filename=in.next(); Scanner input=new Scanner(new File(filename)); System.out.println("Enter name of output file"); filename=in.next(); PrintStream output=new PrintStream(new File(filename)); output.println("   name       test1     test2        test3         test4         test5      average     grade"); while(input.hasNext())     {     name=input.next();    output.print(name+" ");    for(i=0;i=80)      return 'B'; else if (average>=70)      return 'C'; else if (average>=60)      return 'D'; else      return 'F'; }    }
