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.

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 char getGrade(double average){

      char grades[] = {'A','B','C','D','F'};

      if(average >=90 && average<=100){

          return grades[0];

      }

      else if(average >=80 && average<90){

      else if(average >=70 && average<80){

          return grades[2];

      }

      else if(average >=60 && average<70){

          return grades[3];

      }

      else {

          return grades[4];

      }

      double average = 0;

its b

hope this
