Solveby Sava**12.27 (Replace words) Suppose you have a lot of files in a directory that containwords Exercisei_j, where i and j are digits. Write a program that pads a 0before i if i is a single digit and O before j if jis a single digit. For example, theword Exercise2_1 in a file will be replaced by Exercise02_01. In Java, whenyou pass the symbol from the command line, it refers to all files in the direc-tory (see Supplement III.V). Use the following command to run your program:java Exercise12 27

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...
<<Write in Java>> - Challenge 7 File encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will be a version of the first file, but written in a secret code. Although there are complex encryption techniques, you should come up with a simple one of your own. For example, you could read the first file one character at a time, and add 10 to the character code of each character before it is written to the second file. - Challenge 8 Write a program that decrypts the file produced by the program in Programming Challenge 7. The decryption program should read the contents of the coded file, restore the data to its original state, and write it to another file

CISP 1010, Lab 3, Arrays and C-Strings Introduction This application creates Mad Lib™ haikus based upon user input. Detailed Information The application reads three-line haikus into a two-dimensional array of characters (an array of C-strings, not C++ string objects) from an input file called haikus.dat. Do not ask the user for this file name. Just open it and read its contents into a two-dimensional array. A sample input file with two haikus is shown below. Flowers sit in * Shades of the * tree near * in sunset When begins the * And the * Crocus blooms * any thing The asterisk will actually be in the file. They indicate where words that the user enters go in the haiku. The asterisk on the first line will be replaces by a one syllable noun and on the second line will be replaced by a two syllable adjective. These two askterisks will never be the first character of the line. The asterisk on the third line will always be the first character on the line and will be replaced by a gerund (a…
I need help with this homework question. Someone answered before but the output was incorrect. Programing Language: C++. Please do not use a string varible and add notes for understanding. 6.13: Word CountWrite a program that prompts the user to input the name of a text file and then outputs the number of words in the file. You can consider a “word” to be any text that is surrounded by whitespace (for example, a space, carriage return, newline) or borders the beginning or end of the file. Input Notes:There are two input sources in this program: the text file and standard input. The standard input consists of a single word, the name of the text file to be read. Output Notes (Prompts and Labels): The filename provided in standard input is prompted for with "Enter a file name: " and displayed so that the filename entered is on the same line as the prompt. The output of the program is a single line of the form: "The file contains N words." where N is the number of words determined by the…
