how to calc the grade by using java import java.util.Scanner;

public class CodesCracker { public static void main(String[] args) { float[] marks = new float[8]; float sum=0, avg; int i; Scanner scan = new Scanner(System.in);

  System.out.print("Enter Marks Obtained in 8 Subjects: ");
  for(i=0; i<8; i++)
     marks[i] = scan.nextFloat();
  
  for(i=0; i<8; i++)
     sum = sum + marks[i];
  avg = sum/8;
  
  System.out.print("\nGrade = ");
  
  if(avg>=94)
     System.out.println("A");
  else if(avg>=90 && avg<94)
     System.out.println("A-");
  else if(avg>=87 && avg<90)
     System.out.println("B+");
  else if(avg>=83 && avg<87)
     System.out.println("B");
  else if(avg>=80 && avg<83)
     System.out.println("B-");
  else if(avg>=77 && avg<80)
     System.out.println("C+");
  else if(avg>=73 && avg<77)
     System.out.println("C");
  else if(avg>=70 && avg<73)
     System.out.println("C-");
  else if(avg>=67 && avg<70)
     System.out.println("D+");
  else if(avg>=63 && avg<67)
     System.out.println("D");
  else if(avg>=60 && avg<63)
     System.out.println("D-");
  else
     System.out.println("F");

} }
