What is the code in java by using array for a program to calculate electricity bill?

Answer 1

Here's a simple Java program that uses an array to calculate electricity bills based on units consumed:

import java.util.Scanner;

public class ElectricityBill {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        double[] charges = new double[5]; // Assuming 5 customers
        double ratePerUnit = 5.0; // Example rate per unit

        for (int i = 0; i < charges.length; i++) {
            System.out.print("Enter units consumed by customer " + (i + 1) + ": ");
            int units = scanner.nextInt();
            charges[i] = units * ratePerUnit; // Calculate bill
        }

        System.out.println("Electricity Bills:");
        for (int i = 0; i < charges.length; i++) {
            System.out.println("Customer " + (i + 1) + ": $" + charges[i]);
        }
        scanner.close();
    }
}

This program prompts the user to enter the units consumed by multiple customers, calculates their bills based on a fixed rate, and displays the results.
