Write a program in Java that reads the file and does two things:
Write to an output file called
dataSwitch.txt
the same data from the input file, but switch the
order of the data entries on each line. For example, if the first line of the input file is
“90001 57110”, the first line of the output file would be “57110 90001”.
Additionally, print to the screen the number of lines in the file with a label
/* * Java Program for data switch */ import java.io.*; import java.util.*; public class Main { public static void main(String args[]) { try { Scanner inFile = new Scanner(new File("in.txt")); FileWriter outFile = new FileWriter("out.txt"); int countLines = 0; while (inFile.hasNextLine()) { int first = inFile.nextInt(); int last = inFile.nextInt(); outFile.write(Integer.toString(last) + " " + Integer.toString(first) + "\n"); countLines++; } System.out.println("Number of lines in a file: " + countLines); inFile.close(); outFile.close(); } catch (FileNotFoundException e) { System.err.println("File not found. Please scan in new file."); } catch (IOException e) { System.out.println("IO Error occurred."); e.printStackTrace(); } } }

IN JAVA. Write a program that reads a file (provided as attachment to this assignment) and writes the file to a different file with line numbers inserted at the beginning of each line. For example if file input is: This is a test File output should be 1. This is a test ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ BELOW FROM NOTEPAD FILE. This file contains lines of text to determine if you can properly read and write from a file.
Write a Java program called EqualSubsets that reads a text file, in.txt, that contains a list of positive and negative integers (duplicates are possible) separated by spaces and/or line breaks. Zero may be included. After reading the integers, the program saves them in a singly linked list in the same order in which they appear in the input file. Then, without changing the linked list, the program should print whether there exists two subsets of the list whose sums are...
Write a complete Java program in a file caled Module1Progrom.java that reads all the tokens from a file named dota.txt that is to be found in the same directory as the running program. The program should ignore al tokens that cannot be read as an integer and read only the ones that can. After reading all of the integers, the program should print all the integers back to the screen, one per line, from the smalest to the largest. For...
( IN JAVA): Write a program that reads each line in a file, and writes them out in reverse order into another file. This program should ask the user for the name of an input file, and the name of the output file. If the input file contains: Mary had a little lamb Its fleece was white as snow And everywhere that Mary went The lamb was sure to go Then the output file should end up containing: The lamb...
java Program Write a program called Copy that accepts the names of an input file and an output file on the command line and copies the contents of the input file to the output file, for example, csc$ java Copy infile.txt outfile.txt

Write a Java program in Eclipse that reads from a file, does some clean up, and then writes the “cleaned” data to an output file. Create a class called FoodItem. This class should have the following: A field for the item’s description. A field for the item’s price. A field for the item’s expiration date. A constructor to initialize the item’s fields to specified values. Getters (Accessors) for each field. This class should implement the Comparable interface so that food...
In either Java or Python 3, write a program that simulates a deterministic FSM. It will read from two input files. The first is a file describing an FSM The first line contains the alphabet as a series of characters separated by a single space - The second line contains the number of states as an integer k 2 1; states will be numbered 0,1,..., k -1. The start state is always state O The third line contains a series...

C++ please Write a program that reads the following sentences from a file: I am Sam Sam I am That Sam I am That Sam I am I do not like that Sam I am Do you like green eggs and ham I do not like them But I do like spam! You will first have to create the text file containing the input, separate from your program. Your program should produce two output files: (i) (ii) one with the...
