A hotel salesperson enters sales in a text file. Each line contains the following, separated by semicolons: The name of the clie

nt, the service sold (such as Dinner, Conference, Lodging, and so on), the amount of the sale, and the date of that event. Write a java program that reads such a file and displays the total amount for each service category. Display an error if the file does not exist or the format is incorrect. Make sure the program can read a text file and that writes a separate file for each service category, containing the entries for that category. Name the output files Dinner.txt, Conference.txt, and so on.

Answer:

Complete solution is given below:

Explanation:

Java code:

//Header file section

import java.util.Scanner;

import java.io.*;

//main class

public class SalesTestDemo

{

//main method

public static void main(String[] args) throws IOException

{

  String inFile;

  String line;

  double total = 0;

Scanner scn = new Scanner(System.in);

//Read input file name

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

inFile = scn.nextLine();

FileReader fr = new FileReader(new File(inFile));

BufferedReader br = new BufferedReader(fr);

System.out.println("Name \t\tService_Sold \tAmount \tEvent Date");

System.out.println("=====================================================");

line = br.readLine();

//Each line contains the following, separated by semicolons:

//The name of the client, the service sold

//(such as Dinner, Conference, Lodging, and so on)

while(line != null)

{

String temp[] = line.split(";");

for(int i = 0; i < temp.length; i++)

{

System.out.print(temp[i]+"\t");

if(i == 1)

System.out.print("\t");

 

}

//Calculate total amount for each service category

total += Double.parseDouble(temp[2]);

System.out.println();

line = br.readLine();

}

//Display total amount

System.out.println("\nTotal amount for each service category: "+total);

}

}

inputSale.txt:

Peter;Dinner;1500;30/03/2016

Bill;Conference;100.00;29/03/2016

Scott;Lodging;1200;29/03/2016

Output:

Enter input file Name: inputSale.txt

Name        Service_Sold    Amount    Event Date

=====================================================

Peter   Dinner       1500   30/03/2016  

Bill   Conference       100.00   29/03/2016  

Scott   Lodging       1200   29/03/2016  

Total amount for each service category: 2800.0

Write a function in python that computes and returns the sum of the digits for any integer that is between 1 and 999, inclusive.
DanielleElmas [232]

Answer:

def sum_digits(number):

   total = 0

   if 1 <= number <= 999:

       while number > 0:

           r = int (number % 10)

           total +=r

           number /= 10

   else:

       return -1

   return total

   

print(sum_digits(658))

Explanation:

Write a function named sum_digits that takes one parameter, number

Check if the number is between 1 and 999. If it is, create a while loop that iterates until number is greater than 0. Get the last digit of the number using mudulo and add it to the total. Then, divide the number by 10 to move to the next digit. This process will continue until the number is equal to 0.

If the number is not in the given range, return -1, indicating invalid range.

Call the function and print the result

Write a program that asks the user for the number of males and the number of females registered in a class. The program should d
Bond [772]

Answer:

import java.util.Scanner;

public class PercentagePopulation {

public static void main(String[] args) {

 // 1. Create an object of the Scanner class

 // This will allow for user's inputs

 Scanner input = new Scanner(System.in);

 // 2. Create a prompt asking the user to enter the number of males

 System.out.println("Please enter the number of males");

 // 3. Receive the number entered by the user and store in an int

 // variable called  number_of_males.

 int number_of_males = input.nextInt();

 // 4. Create a prompt asking the user to enter the number of

               // females

 System.out.println("Please enter the number of females");

 // 5. Receive the number entered by the user and store in an int

 // variable  called, number_of_females

 int number_of_females = input.nextInt();

 // 6. Find the sum of the number of males and females

 // Store the result in an int variable called total.

 int total = number_of_males + number_of_females;

 // 7. Find the percentage of males by using the appropriate

 // formula.  Do a type-casting to allow for division in floating point

               // representation by prepending the number_of_males by (double)

 double percentagemales = (double) number_of_males / total * 100.0;

 // 8. Find the percentage of females by using the appropriate

 // formula.  Do a type casting to allow for division in floating point

               // representation by prepending the number_of_males by (double)

 double percentagefemales = (double) number_of_females / total * 100.0;

 // 9. Print out the results

 System.out.println("Percentage males : " + percentagemales + "%");

 System.out.println("Percentage females : " + percentagefemales + "%");

}

}
