Input electricity unit charges and calculate total electricity bill
Calculate total electricity bill according to the given condition:
- For first 50 units Tk. 1.50/unit
- For next 100 units Tk. 2.25/unit
- For next 100 units Tk. 3.00/unit
- For unit above 250 Tk. 3.75/unit
Sample Output
Input electricity unit charges and calculate total electricity bill. Enter unit: 50 Total cost: 90.0
Java-Source Code
//package ifelsejava;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
double unit, surcharge, taka = 0;
Scanner input = new Scanner(System.in);
System.out.println("Input electricity unit charges and calculate total electricity bill.\n");
System.out.print("Enter unit: ");
unit = input.nextDouble();
if (unit >= 1 && unit <= 50) {
//For first 50 units Tk. 1.50/unit
taka = unit * 1.5;
surcharge = taka * 0.2; //Surcharge 20%
taka = taka + surcharge;
} else if (unit >= 51 && unit <= 100) {
//For next 100 units Tk. 2.25/unit
taka = unit * 2.25;
surcharge = taka * 0.2; //Surcharge 20%
taka = taka + surcharge;
} else if (unit >= 101 && unit <= 250) {
//For next 100 units Tk. 3.00/unit
taka = unit * 3.0;
surcharge = taka * 0.2; //Surcharge 20%
taka = taka + surcharge;
} else if (unit >= 251) {
//For unit above 250 Tk. 3.75/unit
taka = unit * 3.75;
surcharge = taka * 0.2; //Surcharge 20%
taka = taka + surcharge;
}
System.out.println("Total cost: " + taka);
}
}
Sample Output
Input electricity unit charges and calculate total electricity bill. Enter unit: 300 Total cost: 1350.0
