Suppose you have Java source files under the directories
chapter1, chapter2, . . . , chapter34. Write a
package chapteri; as the first line for each Java source file under the directory
chapteri.
Step by step
Solved in 3 steps with 3 images
- Suppose you have Java source files under the directorieschapter1, chapter2, . . . , chapter34. Write a program to insert thestatement package chapteri; as the first line for each Java source file underthe directory chapteri. Suppose chapter1, chapter2, . . . , chapter34are under the root directory srcRootDirectory. The root directoryandchapteridirectory may contain other folders and files. Use the followingcommand to run the program:java Exercise12_18 srcRootDirectoryWrite a Java program to file student information in a student directory of your project folder. Create a student directory in your project directory to store all student file. Each file should have the student name, age, major and gender. Each of these student entriesshould be on a separate line.You are a cyber investigator, your task is to write a python program that can read file signatures from a file and save them into a list. Each file signature is an element of your list. Then, try to find out if there is a JPG file in there. If there is a JPG file, print out a True on screen. (File Signature for JPG file is: FF D8 FF DB) The input file is: FSCS360_Midterm_Exam_Part2.txt
- In this assignment, you will create a Java program to read undergraduate and graduate students from an input file, sort them, and write them to an output file. This assignment is a follow up of assignment 5. Like assignment 5, your program will read from an input file and write to an output file. The input file name and the output file name are passed in as the first and second arguments at command line, respectively. Unlike assignment 5, the Student objects are sorted before they are written to the output file. • The program must implement a main class, three student classes (Student, UndergradStudent, GradStudent), and a Comparator class called StudentIDComparator. • The StudentIDComparator class must implement the java.util.Comparator interface, and override the compare() method. Since the Comparator interface is a generic interface, you must specify Student as the type parameter when defining the StudentIDComparator class, i.e., public class StudentIDComparator implements…In this assignment, you will create a Java program to search recursively for files in a directory.• The program must take two command line parameters. First parameter is the folder to search for. Thesecond parameter is the filename to look for, which may only be a partial name.• If incorrect number of parameters are given, your program should print an error message and show thecorrect format.• Your program must search recursively in the given directory for the files whose name contains the givenfilename. Once a match is found, your program should print the full path of the file, followed by a newline.• You can implement everything in the main class. You need define a recursive method such as:public static search(File sourceFolder, String filename)For each subfolder in sourceFolder, you recursively call the method to search.• A sample run of the program may look like this://The following command line example searches any file with “Assignment” in its name%java FuAssign7.FuAssignment7…Write a program that removes all the occurrences of a specified string from a text file. For example, invoking java Exercise12_11Manav filename removes the stringManav from the specified file. Your program should get the arguments from the command line.using java
- When you compile and run packaged software from an IDE, the execution process can be as easy as clicking a run icon, as the IDE will maintain the classpath for you and will also let you know if anything is out of sorts. When you try to compile and interpret the code yourself from the command line, you will need to know exactly how to path your files. Let us start from c:\Code directory for this assignment. Consider a java file who's .class will result in the com.CITC1318.course package as follows: package com.CITC1318.course; public class GreetingsClass { public static void main(String[] args) { System.out.println("$ Greetings, CITC1318!"); } } This exercise will have you compiling and running the application with new classes created in a separate package: 1. Compile the program: c:\Code>javac -d . GreetingsClass.java 2. Run the program to ensure it is error-free: c:\Code>java -cp . com.CITC1318.course.GreetingsClass 3. Create three classes named Chapter1, Chapter2, and Chapter3…Implement (in Java) a console application for writing data to a sequential text file with a formatter class in Java : a. Implement createFile() method – To open/create a new file named as ‘mec.txt’ with explanations of the methods involved. b. Implement writeRecord() method – User enter the employee name, employee id, gross salary, tax rate, income tax and net salary from the keyboard and write/add these values to the file ‘mec.txt’ with explanations of the methods involved. The input fields must be validated as necessary. c. Implement closeFile() method – Close the file with explanations of the methods involved.write a program with python that asks the user to enter two filenames. One filecontains a list of words that you want to count. For the following explanation, let’s call it words.txt.(When your program runs, the user could type a different name. Do not hardcode any filenames inyour code.) The second file contains the text that you want to search for each word. For theexplanation, let’s call it story.txt.Ask the user to enter the name of each file. Assume that the files are located in the same directoryas your code file.For each word in words.txt, search through story.txt and count how many times the word occurs.Print a summary similar to the sample output below.Note 1: You should consider a “word” to be anything bounded by whitespace. You do not need todo any processing to account for punctuation or other special characters. For example, in thesample below, “time.” (with a period) is not considered the same as the word “time” (without aperiod). Capitalization will also matter. “The”…
- Note: You must use proper naming convention for the Java code and you need to briefly elaborate keywords, concept, and logic in your own words. Task 2.2. Using the same scenario, implement (in Java) a console application for writing data to a sequential text file with a formatter class in Java. Implement createFile() method - To open/create a new file named as 'mec.txť with explanations of the methods involved. Implement writeRecord() method – User enter the employee name, employee id, gross salary, tax rate, income tax and net salary from the keyboard and write/add these values to the file 'mec.txt' with explanations of the methods involved. The input fields must be validated as necessary. Implement closeFile() method – Close the file with explanations of the methods involved. Note: You must use proper naming convention for the Java code and you need to briefly elaborate keywords, concept, and logic in your own words. Task 3 Dranare a ranort to nrocent the work done from taek 2 The…Write a Java program that opens a file and counts the whitespace-separated words in that file. You may obtain the name of the input file either from the command line or via prompt and user input. Be sure to clearly document the method chosen. You may test your program using any number of text files; however, you must be sure to test your program using the Sample Text File provided at the end (excerpt.txt). Sample Text File There was nothing so VERY remarkable in that; nor did Alice think it so VERY much out of the way to hear the Rabbit say to itself, `Oh dear! Oh dear! I shall be late!' (when she thought it over afterwards, it occurred to her that she ought to have wondered at this, but at the time it all seemed quite natural); but when the Rabbit actually TOOK A WATCH OUT OF ITS WAISTCOAT- POCKET, and looked at it, and then hurried on, Alice started to her feet, for it flashed across her mind that she had never before seen a rabbit with either a waistcoat-pocket, or a watch to…in C# Look at Figures 9-35 and 9-36 on page 392 of your book. There should be two blocks of code: A Book class and an AddBooks program. In your IDE, create a new .cs file called books.cs, then type this code (you can type both parts in books.cs), then compile it and run it. NOTE: There IS an error with the code
