Sure! I can help you with that. Let's break down the problem into smaller steps:
Step 1: Set up variables and initialize them
- You will need variables to store the sum of grades, the count of students, and the average grade.
- You can initialize the sum to 0, the count to 0, and the average to 0.0.
Step 2: Accept ten student grades
- Use a loop (such as while or for) to iterate ten times.
- Inside the loop, prompt the user to enter a grade and read the input.
- Add the grade to the sum.
- Increment the count by 1.
Step 3: Calculate the average grade
- After the loop, calculate the average grade by dividing the sum by the count.
Step 4: Determine the letter grade
- Use if statements to check the range of the average grade and assign the respective letter grade.
Step 5: Display the result
- Print the sum of grades, average grade, and the corresponding letter grade.
Below is an example of the Java code that solves the problem:
```java
import java.util.Scanner;
public class GradeCalculator {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int sum = 0;
int count = 0;
double average = 0.0;
while(count < 10) {
System.out.print("Enter a grade: ");
int grade = scanner.nextInt();
sum += grade;
count++;
}
average = (double) sum / 10;
String letterGrade;
if (average >= 95) {
letterGrade = "A+";
} else if (average >= 90) {
letterGrade = "A";
} else if (average >= 85) {
letterGrade = "B+";
} else if (average >= 80) {
letterGrade = "B";
} else if (average >= 75) {
letterGrade = "C+";
} else if (average >= 70) {
letterGrade = "C";
} else if (average >= 65) {
letterGrade = "D+";
} else if (average >= 60) {
letterGrade = "D";
} else {
letterGrade = "F";
}
System.out.println("Sum of grades: " + sum);
System.out.println("Average grade: " + average);
System.out.println("Letter grade: " + letterGrade);
}
}
```
To run this program, save the code in a file with a `.java` extension (e.g., `GradeCalculator.java`) and compile it using the `javac` command. After that, run the compiled code using the `java` command. You will then be prompted to enter ten grades, and the program will display the sum, average, and letter grade based on the logic provided.
I hope this helps you! Let me know if you have any further questions.
