- Write a complete program that uses an ifstream object to read integers from a file called numbers.txt, and an ofstream object to write into a file called evens.txt.Your program should have loop that reads each integer from the input file, then writes it into the output file if it is an even number. Write each even number in na separate line.Make sure to close both files before your program terminates.arrow_forwardWrite a complete program that uses an ifstream object to read integers from a file called numbers.txt, and an ofstream to write into a file called doubles.txtYour program should have a loop that reads five integers from the input file, then writes the doouble of each (x2) into the input file. Write each value in a separate line.Make sure to close both files before your program terminates.arrow_forwardWrite a program that opens a text file called quiz.txt for reading. This file contains a single linewith a student’s first name then one space, then the student’s last name, then one space, then somenumber of quiz scores that, if they exists, are separated by one space. The student will have betweenzero and ten scores (inclusive), and each score is an integer between 0 and 100 (inclusive). The filemay or may not end with a new line character. Your program will read the data from this file andwrite its output to a second file. The data in the output file (named average.txt) will contain thestudent’s quiz scores followed by the average of the student’s quiz scores.The output file must be formatted as described below.1. Each quiz score should be listed in a right-justified column that is 4 characters wide. Notethat if a student has fewer than 10 scores (they have missed one or more of the quizzes), yourprogram will need to display the missing score(s) using 0 for each one.2. The average…arrow_forward
- As in Self-Test Exercise 5, write some code that will create a stream namedoutStream that is a member of the class PrintWriter, and that connects thisstream to a text file named sam so that your program can send output to the file.This time, however, do it in such a way that, if the file sam already exists, the oldcontents of sam will not be lost, and the program output will be written after theold contents of the file.arrow_forwardCreate a text file of names, (3 names per line, 5 lines in total) followed by an age for each name. Go through the file and sum the ages. Create an output file with each persons name followed by age and then a line at the end of the output file that says “sum of all ages is: x”. Simple Java programming. Should include things like bufferedReader, fileReader, printWriter, fileWriter, file close, try-with-resources, Scanner, catch/try, etc. Include Java file and txt file. Thank you.arrow_forwardCreate a simple java program that reads all the content in a .txt file, the user will enter the filename to be opened and once opened with any stream of choice, all the content in the file is printed to the screen. You are additionally expected to deal most common exceptions(See samples below) [HINT: DO NOT PROVIDE A PATH BUT RATHER ONLY OPEN THE FILE WITH RELATIVE PATH/FILENAME] Sample run 1: Enter filename: input.txt sample output 1: Hello files, I got the content NB: input.txt contains "Hello files, I got the content" as the data [See sample file] Sample run 2: Enter filename: myText.txt sample output 2: Invalid file : myText.txt could not be found in the current directory NB: myText.txt is not a valid file Requested files InClassDemo.java input.txt 1 Hello files, I got the contentarrow_forward
- Create a simple java program that reads all the content in a .txt file, the user will enter the filename to be opened and once opened with any stream of choice, all the content in the file is printed to the screen. You are additionally expected to deal most common exceptions(See samples below) [HINT: DO NOT PROVIDE A PATH BUT RATHER ONLY OPEN THE FILE WITH RELATIVE PATH/FILENAME] Sample run 1: Enter filename: input.txt sample output 1: Hello files, I got the content NB: input.txt contains "Hello files, I got the content" as the data [See sample file]arrow_forwardWrite a program that reads two input files whose lines are ordered by a key data field. Your program should merge these two files, writing an output file that contains all lines from both files ordered by the same key field. As an example, if two input files contain student names and grades for a particular class ordered by name (the key field), merge the information as shown below. File 1 and file 2 are supplied. Here is an algorithm to merge the data from two files: Read a line from each data file While the end of both files has not been reached While the end of both files has not been reached Write the line from file 1 to the output file and read a new line from file 1. Else Write the line from file 2 to the output file and read a new line from file 2. Write the remaining lines (if any) from file 1 to the output file. Write the remaining lines (if any) from file 2 to the output file. See the Merging Filesslides attachedto the project in Canvasfor a visual look at this algorithm.arrow_forwardWrite a program that reads data from a file specified by the user at runtime (i.e. your program should accept the filename as user input) and stores the output in the file Ch3_Ex5Output.dat. To test your program, use the Ch3_Ex5Data.txt file.arrow_forward
- Write a program, and store it in a file called Travel Expenses.xlsm, that does the following: (a) It asks for a person’s first name and stores it in firstName; (b) it asks for a person’s last name and stores it in lastName; (c) it asks for the number of miles the person traveled on a recent trip and stores it in nMiles; (d) it asks for the average miles per gallon the person got on the trip and stores it in milesPer- Gallon; (e) it asks for the average price per gallon paid for gas on the trip and stores it in avgPrice; (f) it calculates the cost of the trip and stores it in tripCost; and (g) it displays a message such as "Bob Jones traveled 800 miles, got 31.3 miles per gallon on average, paid $3.49 per gallon on average, and paid a total of $89.20 for gas." Make sure there is an Option Explicit line at the top of the module and that you declare all of your variables appropriately.arrow_forwardWrite a small program that copies everything in a tet file to another file. The text file is calledin.txt and the output file is called out.txt. Two files should be exactly the same after copying(the first file shouldn’t be changed, and the second file should be the same as the first one).Your program should define a function called copyFile to copy the input file to the output filewith two arguments: a file pointer to the input file and a file pointer to the output file. You shouldnot and do not need to use an array during copying.arrow_forwardWrite a program that reads the contents of a text file and prints the letter that starts the mostunique words in that file.arrow_forward
