Question
evelop a Java program that calculates the average of three floating-pointnumbers and displays a grade based on the average.
Solution
Sure, here is a simple Java program that calculates the average of three floating-point numbers and displays a grade based on the average.
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Enter three floating-point numbers:");
float num1 = input.nextFloat();
float num2 = input.nextFloat();
float num3 = input.nextFloat();
float average = (num1 + num2 + num3) / 3;
System.out.println("The average is: " + average);
if (average >= 90) {
System.out.println("Grade: A");
} else if (average >= 80) {
System.out.println("Grade: B");
} else if (average >= 70) {
System.out.println("Grade: C");
} else if (average >= 60) {
System.out.println("Grade: D");
} else {
System.out.println("Grade: F");
}
}
}
This program works as follows:
- It prompts the user to enter three floating-point numbers.
- It calculates the average of these numbers.
- It prints the average.
- It checks the average and prints the corresponding grade. If the average is 90 or above, it prints "Grade: A". If it's 80 or above but less than 90, it prints "Grade: B", and so on. If the average is less than 60, it prints "Grade: F".

Write a Java program that determines a student’s grade. The program will read three types ofscores(quiz, mid-term, and final scores) and determine the grade based on the following rules: -if theaverage score >=90% =>grade=A -if the average score >= 70% and <90% => grade=B -if theaverage score>=50% and <70% =>grade=C -if the average score<50% =>grade=F
Single File Programming QuestionProblem StatementJamie is managing a school and is looking to find out the number of students in the class based on the sum of their scores and the average score.He wants to design a program that takes the average score and sum of scores as input and outputs the calculated number of students in the class using pointers.Input format :The first line of input consists of an integer value n, representing the sum of scores.The second line of input consists of a floating-point value f, representing the average score.Output format :The output displays the calculated number of students in the class.Refer to the sample output for the formatting specifications.Code constraints :In this scenario, the test cases fall under the following constraints:1 ≤ n ≤ 1051.0 ≤ f ≤ 100.0Sample test cases :Input 1 :187575.45Output 1 :24Input 2 :20010.25Output 2 :19Note :The program will be evaluated only after the “Submit Code” is clicked.Extra spaces and new line characters in the program output will result in the failure of the test case.Marks : 10Negative Marks : 0WhitelistSet 1:*
Write a program that repeatedly asks for numbers. When the user enters 0, the program prints the average of all numbers entered (excluding the 0) accurate to two decimal places and exits.
