Explanation / Answer

We are usign a hash map to store grade and gpa table.Below is the code

import java.util.*;
public class Grade{

public static void main(String []args){

HashMap<String,Double> symbol_table=new HashMap<String,Double>();

symbol_table.put("A+",4.33);
symbol_table.put("A",4.00);
symbol_table.put("A-",3.67);
symbol_table.put("B+",3.33);
symbol_table.put("B",3.00);
symbol_table.put("B-",2.67);
symbol_table.put("C+",2.33);
symbol_table.put("C",2.00);
symbol_table.put("C-",1.67);
symbol_table.put("D",1.00);
symbol_table.put("F",0.00);

int n,i;
String[] grade;
Scanner sc = new Scanner(System.in);

System.out.println("Enter the number of grades");
n=sc.nextInt();
grade=new String[5];

System.out.println("Enter the grades");
for(i=0;i<n;i++)
grade[i]=sc.next();

double average=0;
for(i=0;i<n;i++)
{
System.out.println("GPA for Grade "+grade[i]+" is "+symbol_table.get(grade[i]));
average=average+symbol_table.get(grade[i]);
}
System.out.println("GPA after calculating Average is "+average/n);

}
}

First number of grade will be inputted ,followed by grades

Sample Input

4
A
A+
C+
B-

Sample Output

GPA for Grade A is 4.0
GPA for Grade A+ is 4.33
GPA for Grade C+ is 2.33
GPA for Grade B- is 2.67
GPA after calculating Average is 3.3325
