GST calculation

 INCLUDE GST CALCULATION 

      To calculate GST (Goods and Services Tax) in Java, you'll need to define a class to represent a product and then perform the calculations based on the quantity and GST rate. 

      Below is a simple Java program that demonstrates how to calculate the GST for a product.

JAVA CODE :

import java.util.Scanner;

public class GSTCalculator {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

        System.out.print("Enter product name: ");

        String productName = scanner.nextLine();

        System.out.print("Enter quantity: ");

        int quantity = scanner.nextInt();

        System.out.print("Enter price per unit: ");

        double pricePerUnit = scanner.nextDouble();

        System.out.print("Enter GST rate (as percentage): ");

        double gstRate = scanner.nextDouble();

        double totalAmountBeforeGST = pricePerUnit * quantity;

        double gstAmount = (gstRate / 100) * totalAmountBeforeGST;

        double totalAmountIncludingGST = totalAmountBeforeGST + gstAmount;

        System.out.printf("Product Name: %s%n", productName);

        System.out.printf("Quantity: %d%n", quantity);

        System.out.printf("Price per Unit: %.2f%n", pricePerUnit);

        System.out.printf("GST Rate: %.2f%%%n", gstRate);

        System.out.printf("Total Amount before GST: %.2f%n", totalAmountBeforeGST);

        System.out.printf("GST Amount: %.2f%n", gstAmount);

        System.out.printf("Total Amount including GST: %.2f%n", totalAmountIncludingGST);

        scanner.close();

    }

}

OUTPUT :

Enter product name: Keyboard

Enter quantity: 2

Enter price per unit: 1200

Enter GST rate (as percentage): 5

Product Name: Keyboard

Quantity: 2

Price per Unit: 1200.00

GST Rate: 5.00%

Total Amount before GST: 2400.00

GST Amount: 120.00

Total Amount including GST: 2520.00
