Using Java, Write a program that reads an input file and writes an output file inserted using try and catch blocks as follows: input Discrete Math Operating System Data Structure Analysis of Algorithms Math 302CS 301 CS 287 CS 350 output 1 Discrete Math 2 Operating System 3 Data Structure 4 Analysis of Algorithms 5 Math 302 6 CS 301 7 CS 287 8 CS 350 1. Print your output to your console first. (Use the File & Scanner classes.) 2. If it works, print your output to your output file. ( Use the FileOutputStream & PrintWriter classes.)

Write a program to draw a quiz score histogram. Your program shouldread data from a file. Each line of the file contains a number in the range0-10. Your program must count the number of occurrences of each scoreand then draw a vertical bar chart with a bar for each possible score (0-10) with a height corresponding to the count of that score. For example,if 15 students got an 8, then the height of the bar for 8 should be 15.Hint: Use a list that stores the count for each possible score. An examplehistogram is shown below: o o D D0 1 2 3 4 5 6 7 8 9 10

Write a C++ program using classes that readslines from a file until the end of file. The program should prompt the user for the file name to read from. The program should open the file for reading, and if the filecannot be opened, print the message "File couldn’t be opened", followed by a space and the filename, and exit. The program should keep track of the number of lines, the number of non-blank lines, the number of words, and the number of integers read from the file.

Need help writing this java code, it has three objectives: to process strings to compare, search, sort, and verify location of specific pattern to output result via interface Description Write a Java program to read a text file (command line input for file name), process the text file and perform the following. Print the total number of words in the file. (When using java_test.txt, I calculate the number of words, including number, as 254.) Print the total number of different words (case sensitive, meaning "We" and "we" are two different words) in the file. (When using java_test.txt, I calculate the number of different words, including number, as 168.) Print all words in ascending order (based on the ASCII code) without duplication. Write a pattern match method to find the location(s) of a specific word. This method should return all line number(s) and location(s) of the word(s) found in the file. Print all line(s) with line number(s) where the word is found by invoking the method...

Java Your program must read a file called personin.txt. Each line of the file will be a person's name, the time they arrived at the professor's office, and the amount of time they want to meet with the professor. These entries will be sorted by the time the person arrived. Your program must then print out a schedule for the day, printing each person's arrival, and printing when each person goes in to meet with the professor. You need to print the events in order of the time they happen. In other words, your output will be sorted by the arrival times and the times the person goes into the professor's office. In your output you need to print out a schedule. In the schedule, new students go to the end of the line. Whenever the professor is free, the professor will either meet with the first person in line, or meet with the first person in line if nobody is waiting. Assume no two people arrive at the same time. You should solve this problem using a stack and a queue. You can only...

python: Write a program that will open the file dataFile.csv Download dataFile.csv, read its contents and print them out. Your output should look like this: First Last Age Wagejane Smith 21.00 21.50Jack Jones 20.00 19.50Edgar Martinez 22.00 22.75Zanab Sayegh 21.00 21.75

Write a C LANGUAGE program to count the length of each word present in an input file(input.txt). You have to write the length of the word and the word itself in a new file. Theword length and the word itself should be separated by a :.The input file contains asingle word per line. You can give any name to your files.For example: if the input file contains:Iamanewfile.Pleasecountonme.234567890Then the output file should contain:1:I2:am1:a3:new5:file.6:Please5:count2:on3:me.9:234567890. NOTE:: USE ONLY BASIC CONCEPTS functions,recursion,file handling,loops,pointers etc.

Write a program that reads data from a file containing integers that ends with -999. Output the numbers that are divisible by 7 Output the numbers that are divisible by 11 Output the numbers that are not divisible by 7 or 11

Assume that you are designing a simple text editor (like Notepad) that supports inserting text, copy, paste and editing for any size file (including book-length files). Between the String objects and StringBuffer objects, which one is more appropriate and why? O String, because StringBuffer is read-only String, because it will execute more efficiently String, because only simple operations are needed StringBuffer, because it allows for changing the characters stored in the object StringBuffer, because it has copy and paste methods

Write a complete java program that: asks the user for a file name tests whether the file exists and tells the user if it does exist asks the user whether it should be deleted. Either delete or do not delete the file based on the user input. If they don't delete, ask them if they would like to write to the file If they want to write, ask what they want to write to the file and write it. Make sure to provide plenty of console output dialog specifying what status/actions are taken at each step.
