ANSWER

import java.util.Scanner;

public class Bill

{

private int bno;

private String name;

private int call;

private double amt;

public Bill() {

bno = 0;

name = "";

call = 0;

amt = 0.0;

}

public Bill(int bno, String name, int call) {

this.bno = bno;

this.name = name;

this.call = call;

}

public void calculate() {

double charge;

if (call <= 100)

charge = call * 0.6;

else if (call <= 200)

charge = 60 + ((call - 100) * 0.8);

else if (call <= 300)

charge = 60 + 80 + ((call - 200) * 1.2);

else

charge = 60 + 80 + 120 + ((call - 300) * 1.5);

amt = charge + 125;

}

public void display() {

System.out.println("Bill No: " + bno);

System.out.println("Name: " + name);

System.out.println("Calls: " + call);

System.out.println("Amount Payable: " + amt);

}

public static void main(String args[]) {

Scanner in = new Scanner(System.in);

System.out.print("Enter Name: ");

String custName = in.nextLine();

System.out.print("Enter Bill Number: ");

int billNum = in.nextInt();

System.out.print("Enter Calls: ");

int numCalls = in.nextInt();

Bill obj = new Bill(billNum, custName, numCalls);

obj.calculate();

obj.display();
