//calculation

double eAverage = (eScore/eGrade*.45);

double tGrade = (eAverage + qAverage + lAverage +5);

System.out.print("Total Score: " + tGrade + " ");

//Get the final Grade

String Grade = "";

if (tGrade <= 100 && tGrade >= 90)

Grade = "A";

else if(tGrade < 90 && tGrade >= 80)

Grade = "B";

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

            Grade = "C";

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

Grade = "D";

else

Grade = "F";

System.out.print("James Bond your grade is a: " + Grade );

}

}

This is my code. My question is how could i add  Method getScores and public static int [] getScores(int [] exams, int [] quizzes,

int [] labs).  and get the same result.

Thank you
