Explanation:

import java.util.Scanner;

class bill {

  public static void main(String[] args) {

      Print("Enter units consumed in kWh: \n");

      Scanner getInput = new Scanner(System.in);

      Print(Calculate_Bill(getInput.nextDouble()));

      getInput.close();

  }

  public static double Calculate_Bill(double kWh) {

      double bill;

      if (kWh <= 100) {

          bill = kWh * 5.5d;

      } else if (kWh >= 100 && kWh <= 200) {

          bill = kWh * 6.0d;

      } else {

          bill = kWh * 7.0d;

      }

      return bill;

  }

  public static void Print(Object _object_) {

      System.out.print(_object_);

  }

}
