How to hold numeric ranges and corresponding letter grade will be stored in a file java

Print the grades on this Logic, this is logic for program and code is written under explanation.

If the average of marks is > = 80 then prints Grade 'A'

If the average is = 70 then prints Grade 'B'

If the average is = 60 then prints Grade 'C'

else prints Grade 'D'

Explanation

import java. util. Scanner;

public class JavaGradeProgram

{

public static void main (String args[])

{

/ * This program assumes that the student has 6 subjects that's why I have created the array of size 6. You can change this as per the requirement. * /

int marks[] = new int[6];

int i;

float total=0, avg;

Scanner scanner = new Scanner (System. in);

for (i=0; i<6; i++) {

System. out. print ("Enter Marks of Subject" + (i+1) + ":");

marks[i] = scanner. nextInt ();

total = total + marks[i];

}

scanner. close ();

Calculate Average Here:

avg = total / 6;

if (avg >=80)

{

system. out. print ("A");

}

else if (avg>=70 && avg <=80)

{

system. out. print ("B");

}

else if (avg>=60 && avg <=70)

{

system. out. print ("C");

}

else

{

system. out. print ("D");

}

}

}
