Hi Friend,

Try the following code:

public class Grader {

public static double find() {

double grades[] = {79, 70, 69, 60, 50, 40};
String final_grade;
double sum, average;
sum = 0;

for (int i = 0; i < grades.length; i++) {
sum += grades[i];
}

average = sum / grades.length;
System.out.println("Average grade = " + average);
return average;
}

public static void main(String[] args) {
Grader g=new Grader();
double average=g.find();
if (average > 70) {
System.out.print("Your Final Grade is A");
} else if ((average > 60) && (average <70)) {
System.out.print("Your Final Grade is B");
} else if ((average >50) && (average < 60)) {
System.out.print("Your Final Grade is C");
} else if ((average >40) && (average < 50)) {
System.out.print("Your Final Grade is D");
} else if (average <40) {
System.out.print("Sorry you not part here, Failed");
}
}
}

Thanks
