- Task 3: Summary We would like to be able to generate a summary for each logfile to give us a rough idea of its contents. Instructions Create a file called Summary.java. As with Task 1, open the file for reading in a try-catch block. Read through the entire file, counting how many of each message/event type occurs. Print out a summary with the count of each event/message type. As a sanity check: the total number of message/event type counts should equal 1000. Hint: a useful method could be String.split. Sample Input/Output Example 1: Summary -------------------- Notifications: 322 Warnings: 326 Errors: 352 Cannot find logfile! Exiting...Question G .This is a java Write a program that reads a file line by line and print each line with a line number. Line number starts at 1 Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this lineIn python, rite a recursive function, displayFiles, that expects a pathname as an argument. The path name can be either the name of a file or the name of a directory. If the pathname refers to a file, its filepath is displayed, followed by its contents, like so: File name: file_path Lorem ipsum dolor sit amet, consectetur adipiscing elit... Otherwise, if the pathname refers to a directory, the function is applied to each name in the directory, like so: Directory name: directory_path File name: file_path1 Lorem ipsum dolor sit amet... File name: file_path2 Lorem ipsum dolor sit amet... ... Test this function in a new program.
- Write a program in python IDLE that allows the user to navigate the lines of text in a file. The program should prompt the user for a filename and input the lines of text into a list. The program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. Actual line numbers range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the line associated with that number.Suppose a library is processing an input file containing the titles of books in order to identify duplicates. Write a program that reads all of the titles from an input file called bookTitles.inp and writes them to an output file called duplicateTitles.out. When complete, the output file should contain all titles that are duplicated in the input file. Note that the duplicate titles should be written once, even though the input file may contain same titles multiple times. If there are not duplicate titles in the input file, the output file should be empty. Create the input file using Notepad or another text editor, with one title per line. Make sure you have a number of duplicates, including some with three or more copies. (Programming Language: Java)Compulsory Task 1 Follow these steps: ● Create a new java file called MyFile.java ● Write code to read the content of the text file input.txt. For each line in input.txt, write a new line in the new text file output.txt that computes the answer to some operation on a list of numbers. ● If the input.txt has the following: Min: 1,2,3,5,6 Max: 1,2,3,5,6 Avg: 1,2,3,5,6 Your program should generate output.txt as follows: The min [1, 2, 3, 5, 6] is 1. The max of [1, 2, 3, 5, 6] is 6. The avg of [1, 2, 3, 5, 6] is 3.4. ● Assume that the only operations given in the input file are min, max and avg and that a list of comma-separated integers always follows the operation. You should define the functions min, max and avg that take in a list of integers and return the min, max or avg of the list. ● Your program should handle any combination of operations and any length of input numbers. You can assume that the list of input numbers are always valid integers and that the list is never empty. ●…
- USE PYTHON Suppose a machine sells bottles of Coca-Cola (Coke) for 50 cents and only accepts coins in these denominations: 25 cents, 10 cents, and 5 cents. In a file called coke.py, implement a program that prompts the user to insert a coin, one at a time, each time informing the user of the amount due. Once the user has inputted at least 50 cents, output how many cents in change, the user is owed. Assume that the user will only input integers, and ignore any integer that isn’t an accepted denomination.Suppose a library is processing an input file containing the titles of books in order to identify duplicates. Write a program that reads all of the titles from an input file called bookTitles.inp and writes them to an output file called duplicateTitles.out. When complete, the output file should contain all titles that are duplicated in the input file. Note that the duplicate titles should be written once, even though the input file may contain same titles multiple times. If there are not duplicate titles in the input file, the output file should be empty. Create the input file using Notepad or another text editor, with one title per line. Make sure you have a number of duplicates, including some with three or more copies.This is Python Program 5: Improve the file copy program from Lab 9 so that it will make sure the user enters a file that exists. If a file doesn’t exist, the open function will raise the FileNotFoundError. You do not need to check if the destination exists since a file doesn’t need to exist to write it. Instead of copying the content of the source as exact, it only copies non-empty lines and it also prepend each line with a line number. A line is empty if the length of the line stripped of white space from both end is 0. The code segment below shows how to strip white space and getting the length of the string. If the length of the line is zero, the line is a blank line. line1 = " " line2 = " aa " print(len(line1.strip())) # 0 print(len(line2.strip())) # 2 In the sample run, “add.py” is the source file and “add-copy.py” is the destination file. Note that “add-copy.py” contains only non-blank lines from “add.py” and each line in “add-copy.py” is labelled with a line number. Sample run:…
- Simple Encryption. Write a java program that reads from a file specified by the user and encrypt the content of the file using a simple shifting technique. Also, ask the user to input the shift size. Output the encrypted message to another file whose filename is also provided by the user. For example, Shift size: 1 Message read from the file: Hello Encrypted message: IfmmpCreate 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.In Python Define a function writeScores with two parameters. The first should be the name of a file, and the second should be a list of integer scores. The set of scores should be appended to the given file, one score per line. Note: The given file will already have the word 'hello' on the first line so make sure you open the file for 'append' rather for 'write'.
