Question

Create a function named calculate_gpa that is given a grade_scale and a student (in that order). It calculates the overall gpa for that student. The student will be in the same format as the example student123 student.

Answer 1

import java.util.ArrayList;

import java.util.Scanner;

public class StudentGrade {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

ArrayList<String> nameList = new ArrayList<String>();

double scores[][] = new double[5][4];

for(int i=0; i<scores.length; i++){

System.out.println("Enter Student "+(i+1)+" Name: ");

nameList.add(scan.nextLine());

System.out.println("Enter Student "+(i+1)+" scores: ");

for(int j=0; j<scores[i].length; j++){

scores[i][j] = scan.nextDouble();

}

scan.nextLine();

}

for(int i=0; i<nameList.size(); i++){

System.out.println("Student "+(i+1)+" Information: ");

System.out.println("Student Name: "+getName(i, nameList));

double average = getAverage(scores, i);

System.out.println("Student Average: "+average);

System.out.println("Student Grade: "+getGrade(average));

}

}

public static double getAverage(double scores[][], int index){

double average = 0;

double sum = 0;

for(int i=0; i<scores[index].length; i++){

}

average = sum / 4;

return average;

}

public static String getName(int index, ArrayList<String> namelist){

return namelist.get(index);

}
