In Java programming Write the code to print out a customer report. Your code must read each customer from a file, populate the object, place the object in a linked list, and display the data from the linked list. Use the customer object name from Customer customer = new Customer ( " customer name" ); Assume you have opened a file and read a line into the customer object. Write the signature line for this method Write the line of code that will write the object to a linked list Write the line of code that will print the customer object properties. Be sure to include a textual description of each property.

A file has r=20000 STUDENT records of fixed-length. Each record has the following fields: NAME (30 bytes), SSN (10 bytes), ADDRESS (40 bytes), PHONE (9 bytes), BIRTHDATE (8 bytes), SEX (1 byte), MAJORDEPTCODE (4 bytes), MINORDEPTCODE (4 bytes), CLASSCODE (4 bytes, integer), and DEGREEPROGRAM (3 bytes). Suppose the block size is 512 bytes. (a) Calculate the record size R in bytes. (b) Calculate the blocking factor (number of tuples per block) and the number of blocks required. (c) Calculate the average block accesses it takes to find a record by doing a linear search on the file. (d) Assume the file is ordered by SSN; calculate the block accesses takes to search for a record given its SSN value by doing a binary search.

I have a text file that have a list of employee's Id and name correspond to it. All the IDs are unique. What I want to do is I want to read from the text file and then sort the Id in order then put it back into the text file. How can I do this in java? Can you write a code for it in java. For example: the text file text.txt contains Id Name 3 Kark 1 Mia 5 Tyrus 2 John After sort, the text.txt will be 1 Mia 2 John 3 Karl 5 Tyrus

A for construct is a loop that goes over a list of objects. Consequently, it runs indefinitely if there are items to process. What do you think about this?

Java programming 1. Write the code that will read the inventory information from a file, populate the object, and populate a linked list with all the inventory objects. Then find a particular item in the linked list based on user input and display the information for that item. Inventory inventory = new Inventory (); Write the line of code to find an inventory object in the linked list using the property for InventoryID

Python S3 Get File In the Python file, write a program to get all the files from a public S3 bucket named coderbytechallengesandbox. In there there might be multiple files, but your program should find the file with the prefix and cb - then output the full name of the file. You should use the boto3 module to solve this challenge. You do not need any access keys to access the bucket because it is public. This post might help you with how to access the bucket. Example Output ob name.txt Browse Resources Search for any help or documentation you might need for this problem. For exampler array indexing, Ruby hash tables, etc.

write in c++Write a program that would allow the user to interact with a part of the IMDB movie database. Each movie has a unique ID, name, release date, and user rating. You're given a file containing this information (see movies.txt in "Additional files" section). The first 4 rows of this file correspond to the first movie, then after an empty line 4 rows contain information about the second movie and so forth. Format of these fields: ID is an integer Name is a string that can contain spaces Release date is a string in yyyy/mm/dd format Rating is a fractional number The number of movies is not provided and does not need to be computed. But the file can't contain more than 100 movies. Then, it should offer the user a menu with the following options: Display movies sorted by id Display movies sorted by release date, then rating Lookup a release date given a name Lookup a movie by id Quit the Program The program should perform the selected operation and then re-display the menu. For...

If wrong answer this time will downvote it Create a class with a static main that tests the ability to resolve and print a Path: • Create an instance of a FileSystem class. • Resolve an instance of a Path interface from a directory path and filename. • Print the constructed Path with System.out.println() method. 2. Create a class with a static main that tests the ability to resolve and print a Path: • Create an array of Path class. • Instantiate instances of Path with absolute and relative paths. • Print the constructed elements of the array of Path class with System.out.println() method. 3. Create a class to test serialisation class that implements serializable, it should implement the following: • A static void method that serialises an object. • A static void method that deserializes an object. • A static main method that tests the two by moving an object from one to the other

write a program for a library automation which gets the isbn number, name, author and publication year of the books in the library. the status will be filled by the program as follows: if publication year before 1985 the status is reference else status is available, the information about the books should be stored inside a linked list. the program should have a menu and the user inserts, displays, and deletes the elements from the menu by write a selecting options. the following data structure should be used. struct list char isbn[ 20 ]: char namei 20 ]. char authori 20 ]: int year; char status[200j: struct list "next, jinfo, wedoad n un posn ag pinogs nuu sulnogoj l press 1. to insert a book press 2. to display the book list press 3. to delete a book from list

Java programming 1. Write the code to print out an individual customer’s information. Your code must read the customer from a file, populate the object, and display the data from the object. Customer customer = new Customer (); 2. Write the signature line for this method 3, Write the line of code to read a line from the file Assume the object has been populated with the proper values. Write the line of code that will print one of the properties in the customer object. Be sure to include a textual description, e.g. "Customer Name: "

C++ Complete the program that will allow the user to enter data on 10 Halloween costumes. The program will create Costume objects and then store the Costume objects in a Hash Table. The Costume ID will be the key and a pointer to the Costume object will be the value. You are given Lab7.cpp, HashEntry.h, and Costume.h and you should not have to make any changes to these files at all. You will need to write HashTable.h, which implements the HashTable class. This should NOT be a template class. Your HashTable class should resolve collisions by linear probing and should use the HashEntry class for the linkedlist nodes. Because we’re using probing, there is no removal function. This is okay for this application, since we want to keep a record of costumes that are no longer being kept in stock. ---GIVEN--- Lab.cpp #include <iostream> #include "HashTable.h" #include "Costume.h" using namespace std; int main() { int size; int key; Costume *newCostume; string name; float price;...
