Hi friend,

Code to solve the problem :

import java.io.*;
import java.text.*;

public class MeterReading {
public static double MyRound(int places, double value) {
return Math.round(value*Math.pow(10, places))/Math.pow(10, places);
}
public static void main(String [] args) throws IOException{
try{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter Current Reading");
int currentReading= Integer.parseInt(br.readLine());

System.out.println("Enter Previous Reading");
int previousReading = Integer.parseInt(br.readLine());

double result = 0;
double rate = 0;
int diffReading = currentReading - previousReading;

if(diffReading<=100)
{
rate = 1.25;
}
else if(diffReading>100 && diffReading<=250)
{
rate = 1.50;
}
else if(diffReading>250 && diffReading<=350)
{
rate = 1.80;
}
else if(diffReading>350)
{
rate = 2.20;
}

double bill = diffReading*rate;


System.out.println("Total Bill : " + MyRound(2,bill));


}
catch(Exception e){
System.out.println("Out of range!");
}
}
}
