An Electricity Board charges for electricity per month from their consumers according to the units consumed. The tariff is given below:

Units Consumed	Charges
Up to 200 units	₹3.80/unit
More than 200 units and up to 300 units	₹4.40/unit
More than 300 units and up to 400 units	₹5.10/unit
More than 400 units	₹5.80/unit

Write a program to calculate the electricity bill taking consumer's name and units consumed as inputs. Display the output.

import java.util.Scanner;

public class KboatElectricBill

    public static void main(String args[]) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter Consumer Name: ");
        String name = in.nextLine();
        System.out.print("Enter Unit's Consumed: ");
        int units = in.nextInt();
        double amt = 0.0;
        if (units <= 200)
            amt = units * 3.8;
        else if (units <= 300)
            amt = (200 * 3.8) + ((units - 200) * 4.4);
        else if (units <= 400)
            amt = (200 * 3.8) + (100 * 4.4) + ((units - 300) * 5.1);
        else
            amt = (200 * 3.8) + (100 * 4.4) + (100 * 5.1) + ((units - 400) * 5.8);

        System.out.println("Units Consumed: " + units);
