Question

Test Scores and Grade

Write a program that has variables to hold three test scores. The program should ask the user to enter three test scores and then assign the values entered to the variables. The program should display the average of the test scores and the letter grade that is assigned for the test score average. Use the grading scheme in the following table:

Test Score Average	Letter Grade
90–100	A
80–89	B
70–79	C
60–69	D
Below 60	F

Hello, I'm having some errors in my code, I was wondering if someone could help me correct it. This is my code:

import.java.util.Scanner;L public class NAM_TestScoresAndGrade { public static void main (String[] args) { double testi, test2, test3, averageScore; char letterGrade; IT Scanner SC = new Scanner(System.in); System.out.print("Enter first test score"); testi - sc.nextDouble(); System.out.print ("Enter second test score"); test2 = sc.nextDouble(); System.out.print("Enter third test score"); test3 = sc.nextDouble(); averageScore= (testi+test+test3)/3; System.out.println("Average score: + averageScore); if (averageScore >= 90 && averageScore <= 100) { letterGrade = 'A'; System.out.println( "Letter grade" + letterGrade); } else if (averageScore >= 80 && averageScore <= 89) { letterGrade = 'B'; System.out.println( "Letter grade" + letterGrade); } else if (averageScore >= 70 && averageScore <= 79) { letterGrade = 'C'; System.out.println( "Letter grade" + letterGrade); } else if (averageScore >= 60 && averageScore <= 69); { letterGrade = 'D';

And this is my errors, I'm not sure how to fix them.

Please help me, and if I have other errors please let me know, thank you!

Answer 1

// NOTE: 2 errors in your code

(1) remove . between import and java import java.util.Scanner;

(2) spelling is wrong in sc.close();

// I have fixed both the errors

import java.util.Scanner;

public class NAM_TestScoresAndGrade {
public static void main(String args[]) {
  
double test1,test2,test3,averageScore;char letterGrade;
  
Scanner sc=new Scanner(System.in);
System.out.print("Enter first test score");
test1=sc.nextDouble();
System.out.print("Enter second test score");
test2=sc.nextDouble();
System.out.print("Enter third test score");
test3=sc.nextDouble();
averageScore=(test1+test2+test3)/3;
System.out.println("Average score: "+averageScore);
if(averageScore>=90 && averageScore<=100)
{
letterGrade='A';
System.out.println("Letter grade"+letterGrade);
}
else if(averageScore>=80 && averageScore<=89)
{
letterGrade='B';
System.out.println("Letter grade"+letterGrade);
}
else if(averageScore>=70 && averageScore<=79)
{
letterGrade='C';
System.out.println("Letter grade"+letterGrade);
}
else if(averageScore>=60 && averageScore<=69)
{
letterGrade='D';
System.out.println("Letter grade"+letterGrade);
}
else if(averageScore<=60)
{
letterGrade='F';
System.out.println("Letter grade"+letterGrade);
}
sc.close();
}
}
