Write some code that will create a stream named outStream that is anobject of the class PrintWriter and that connects this stream to a textfile named sam.txt so that your program can send output to the file. Ifthe file sam.txt does not exist, create a new empty file. However, if a filenamed sam.txt already exists, erase its old contents so the program canstart with an empty file with that name.
Create 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.
Using JAVA
Your client owns a bookstore, and they need to process an input file containing the titles of all their books to remove duplicates. Write a program that reads all of the titles from an input file called SamsBookstore.txt and writes them to an output file called SamsDuplicates.txt. When complete, the output file should contain all duplicated titles found in the input file.

Each row of the .txt file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student, each separated by a space. A sample of the student information is provided in StudentInfo.txt below. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: • Read the file name of the .txt file from the user. • Open the .txt file and read the student information using readline() or readlines(). • Compute the average exam score of each student. • Assign a letter grade to each student based on the average exam score in the following scale: ◦ A: 90 =< x ◦ B: 80 =< x < 90 ◦ C: 70 =< x < 80 ◦ D: 60 =< x < 70 ◦ F: x < 60 • Output the first names, last names, exam scores, and letter…arrow_forwardIN JAVA ONLY PLEASE. POSITIVE REVIEW WILL BE LEFT FOR CORRECT LANGUAGE ONLY AND NOT COPY PASTE FROM INCORRECT ANSWER A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. Ex: If the input of the program is: ParkPhotos.txt and the contents of ParkPhotos.txt are: Acadia2003_photo.jpg AmericanSamoa1989_photo.jpg BlackCanyonoftheGunnison1983_photo.jpg CarlsbadCaverns2010_photo.jpg CraterLake1996_photo.jpg…arrow_forward
- Create a program that reads three lines from a text file. Each line should be read one at a time. For each word on a line, the user should be asked to specify how many syllables are in that word. The program should then inform the user if the file contains a valid Hiku using the function below: def isHiku (firstLine, secondLine, thirdLine):if (firstLine == 5 and secondLine == 7 and thirdLine == 5): return True return False print("The file contains a Hiku:", isHiku(5,7,5))Note: You must replace the values in the function with the numbers counted by your program.arrow_forwardWrite a program that writes user input to a text file and then reads the contents from that file. You will need to perform the following steps. Prompt the user for the name of a file to append to and then another prompt for them to enter a sentence. Open the file they requested in append mode and write the user_sentence to this file. Don't forget to close the file when you are done writing to it (explicitly or implicitly). Open the file you just wrote to in read mode and read the contents of the file. Print the complete file contents to the console/shell. Provide comments in your code to explain the logic used. Ensure your program works as expected by testing it with different sentences.arrow_forwardPlease in C Language Write a program that uses an existing text file (text.txt) to determine the number of occurrences of each letter.

- Write a program that gives and takes advice on program writing. The pro- gram starts by writing a piece of advice to the screen and asking the user to type in a different piece of advice. The program then ends. The next person to run the program receives the advice given by the person who last ran the program. The advice is kept in a file, and the contents of the file change after each run of the program. You can use your editor to enter the initial piece of advice in the file so that the first person who runs the program receives some advice. Allow the user to type in advice of any length so that it can be any number of lines long. The user is told to end his or her advice by pressing the Return key two times. Your program can then test to see that it has reached the end of the input by checking to see when it reads two consecutive occurrences of the character '\n'.arrow_forwardJava Program /The Output attached by image OverviewYou should enter this task, ask the user for a word and then search for a file to see if that word is among the words in the file. Task This exercise comes with three text files named wordlist1.txt, wordlist2.txt and wordlist3.txt. These files contain a large amount of words in English. Each file contains more and more words. Each word in these files is on a separate line and the words contain only lowercase letters. Your task is to write a program that reads all these words from the file and checks if a keyword, which the user entered, is among the entered words. The program should also count the total number of words contained in the file used. The program should measure how long it takes to complete the search, ie how long it takes to read all the words and check if the keyword is among the words or not.
