The telephone department wishes to compute monthly telephone bills

The telephone department wishes to compute monthly telephone bills for its customers on the basis of call made:

Number of calls Rate

First 80 calls Rs.2.50 per call

Next 80 calls 60 paisa per call

Next 160 calls 50 paisa per call

Any call above 280 calls 40 paisa per call

Write a JAVA program to input the number of calls and compute the total bill amount.

import java.util.*;

class Telephonebill
{
public static void main()
{
Scanner Sc=new Scanner(System.in);                                                                                       System.out.println(“Enter no of calls made ”);
double c=Sc.nextDouble();double a=0;
if(c>=80)
{
a=2.50*c;
}                                                                                                                                                                                    else if(c>=80&&c<=160)
{
a=(80*2.50)+((c-180*0.60);
}
else if(c>=160&&c<=280)
{
a=(80*2.50)+(80*0.60)+(( c-160)*0.50);
}
else if(a>=280)
{
a=(80*2.50)+(80*0.60)+(120*0.50)+((c-280)*0.40;
}
{
System.out.println(“Total number of calls made is “+c);
}
{
System.out.println(“Bill amount is “+a);
}   } }

Output: Enter the no. of calls made 200
Total number of calls made is 200
Bill amount is 264

Just copy paste the code into the class file of Bluej compiler. Change the class name according to your's.

Thanks for visting Programming in JAVA

Happy Coding !!
