The marks obtained by a student in 5 different subjects are input through the keyboard. The student gets a division as per the following rules:
Percentage above or equal to 75 – Honors
Percentage above or equal to 60 – First Division
Percentage between 50 and 59 – Second Division
Percentage between 40 and 49 – Third Division
Percentage less than 40 – Fail
Write a program to calculate the division obtained by the student,Create program in java.
import java.util.Scanner;
public class DivisionCalculator {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
// Array to hold marks of 5 subjects
int[] marks = new int[5];
int totalMarks = 0;
// Input marks for 5 subjects
System.out.println("Enter marks for 5 subjects: ");
for (int i = 0; i < 5; i++) {
System.out.print("Subject " + (i + 1) + ": ");
marks[i] = scanner.nextInt();
totalMarks += marks[i];
}
// Calculate percentage
double percentage = totalMarks / 5.0;
// Determine the division based on percentage
String division;
if (percentage >= 75) {
division = "Honors";
} else if (percentage >= 60) {
division = "First Division";
} else if (percentage >= 50) {
division = "Second Division";
} else if (percentage >= 40) {
division = "Third Division";
} else {
division = "Fail";
}
// Display the result
System.out.println("Total Marks: " + totalMarks);
System.out.println("Percentage: " + percentage + "%");
System.out.println("Division: " + division);
}
}
Explanation:
- Import
Scanner: We import theScannerclass to take input from the user. - Main Method: We define the main method where the execution begins.
- Array for Marks: We create an array to store the marks of 5 subjects.
- Input Marks: We use a loop to prompt the user to enter marks for each of the 5 subjects, and we calculate the total marks.
- Calculate Percentage: The percentage is calculated by dividing the total marks by the number of subjects (5).
- Determine Division:
- If the percentage is 75 or above, the division is “Honors”.
- If the percentage is between 60 and 74.99, the division is “First Division”.
- If the percentage is between 50 and 59.99, the division is “Second Division”.
- If the percentage is between 40 and 49.99, the division is “Third Division”.
- If the percentage is below 40, the division is “Fail”.
- Output: The program prints the total marks, percentage, and the division obtained by the student.
You can run this program in any Java IDE or command-line environment and input different marks to test the division calculation.
Another Example
import java.util.Scanner;
public class StudentDivision {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
float[] marks = new float[5];
float total = 0;
float percentage;
// Input marks for 5 subjects
System.out.println("Enter the marks obtained in 5 subjects: ");
for (int i = 0; i < 5; i++) {
System.out.print("Subject " + (i + 1) + ": ");
marks[i] = scanner.nextFloat();
total += marks[i];
}
// Calculate percentage
percentage = (total / 500) * 100;
// Determine division based on percentage
System.out.println("Total Marks = " + total);
System.out.println("Percentage = " + percentage + "%");
if (percentage >= 75) {
System.out.println("Division: Honors");
} else if (percentage >= 60) {
System.out.println("Division: First Division");
} else if (percentage >= 50) {
System.out.println("Division: Second Division");
} else if (percentage >= 40) {
System.out.println("Division: Third Division");
} else {
System.out.println("Division: Fail");
}
scanner.close();
}
}
Explanation:
Importing Scanner Class:
- The
Scannerclass fromjava.utilpackage is imported to take input from the user.
- The
Variable Declaration:
marksarray to store the marks of 5 subjects.totalto store the sum of all marks.percentageto store the calculated percentage.
Input Marks:
- A loop is used to take input for the 5 subjects and simultaneously sum them up into the
total.
- A loop is used to take input for the 5 subjects and simultaneously sum them up into the
Calculate Percentage:
- The percentage is calculated by dividing the
totalby 500 (since there are 5 subjects, and each subject is assumed to be out of 100) and then multiplying by 100.
- The percentage is calculated by dividing the
Determine Division:
- Based on the percentage calculated, the program prints the division according to the given rules.
This Java program will take the marks of 5 subjects from the user, calculate the total and percentage, and then determine and print the division the student falls into.
