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.
Write a program that reads student data from a file, compute their GPA and writes the results to a different file. 1.

Write a program that reads student information from a text file, then creates a text file that records the course grades of the students and a final grade. 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…
Using a text editor, create a file that contains a list of at least 15 six-digit account numbers. Read in each account number and display whether it is valid. An account number is valid only if the last digit is equal to the remainder when the sum of the first five digits is divided by 10. For example, the number 223355 is valid because the sum of the first five digits is 15, the remainder when 15 is divided by 10 is 5, and the last digit is 5. Write only valid account numbers to an output file, each on its own line.*Note that the contents of the file AcctNumsIn.txt will change when the test is run to test the program against different input.

The teacher at a school needs help grading an exam with a number of True/False questions. The students’ IDs and test answers are stored in a file. The first entry of the file contains the answer to the test in the form: TTFTFTTTFTFTFFTTFTTF Every other entry in the file is the student’s ID, followed by a blank, followed by the students’ response. For instance, the entry: ABC54102 T FTFTFTTTFTTFTTF TF The student’s ID is ABC54102, answer to question 1 is True, the answer to question 3 is False. Also, the student did not answer question 2 and question 18. The exam has 20 questions. Here is the grading policy: each correct answer is awarded two points, each wrong answer get -1 point, and no answer gets 0 point. Write a program that processes the test data. The output should be the student’s ID, followed by the answers, followed by the test score (total points), followed by the test grade. Assume the following grade scale will be used: 90%-100%, A; 80%-89.99%, B; 70%-79.99%, C; 60%-69.99%,…
IN 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…
Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students.

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 tsv file from the user. • Open the tsv file and read the student information. • 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: o A: 90 =< x o B: 80 =< x < 90 o C: 70 =< x < 80 o D: 60 =< x < 70 o F:x< 60 Compute the average of each exam. • Output the last names, first names, exam scores, and letter grades of the students into a text file named report.txt.
