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.

Write program that reads a list of names from a data file and displays the names to the console. The program should prompt the user to enter a filename. Create such a file and check your code.  Solve with python. Example of code format:  #Prompt the user for file name file_name = input("Enter file name : ") #Open file  with open(file_name,"r") as file:  #Read file content  f =  file.readline() #split the contents into numbers  numbers = f.split(' ') test_list = [int(i) for i in numbers] res = 1 #Find the product  for i in test_list:  res*=i #Print result  print("Product of numbers in the list :",res)

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…

Suppose you are given a text file that contains the names of people. Every name in the file consists of a first name and last name. Unfortunately, the programmer that created the file of names did not guarantee that each name was on a single line of the file. Read this file of names and write them to a new text file sorted according to first name, one name per line. For example, if the input file contains Ed Marston Bob Jones Jeff Williams Fred Charles   The output file should be Bob Jones Ed Marston Fred Charles Jeff Williams   Use arrays to solve the problem.

All I need is the main.cpp file Programming Specifications: Task:  Two files have been provided (wordcounter.h and wordcount.cpp).  You must open a text file, read in each word until end of file, add each word to the WordCount library and print the report. Your program must request a filename of a text file that contains words to count. You must check to see if it is a valid file and issue an error message if not and request a new file name until a valid one is entered. You must have at least one function that either passes in a parameter and at least one function that returns a value. You can have a single routine that does both. You must declare the class object properly, use AddWord() to add the word to the catalog and use PrintSummary() to produce the output. Design Considerations: The file will contain only words (no punctuation or special characters) less than or equal to 13 letters.  There will be no limit to the number of words. You must open the file and read each…

I am trying to figure out why the sum at the end of my Java code is not working correctly. It keeps showing as zero and I do not know what the issue is. Here is the program requirements Write a program in a single file that: Main: Creates 10 random doubles, all between 1 and 11, Calls a method that writes 10 random doubles to a text file, one number per line. Calls a method that reads the text file and displays all the doubles and their sum accurate to two decimal places.
