Buy now Rolodex Sort: A Rolodex is a rotating file, usually used to record business contact information. Cards are inserted in alphabetic order by name. You operate the Rolodex by rolling it forwards or backwards until you find the information you need (or find the place where a new card should be added). Task Your task is to create a class that simulates a Rolodex, then use it to implement a word-sorting program. The program starts with an empty Rolodex, then reads words from standard input and adds a card for each word in the appropriate position to maintain overall sorted order. To find the correct position, the Rolodex is rolled either backwards or forwards from the current card. When all input has been processed, the program moves the Rolodex to the beginning and then outputs each word in order, one per line.  Source Code Requirements: Download the file rolosort_0.zip, which contains a basic version of the program and a skeleton version of the Rolodex class. The class has meth...

Project Description Continuing the theme of project 3, adjust the program so that the left text area displays the words using a Hashmap (the order of the words will be unpredictable), and the right text area displays the words using a TreeMap (the words should be in sorted order). If you did not get project 3 to work entirely, you are not responsible for the menus and menu items for the project, or for adding additional words, or for displaying only nouns or verbs. For project 4 you are only responsible for displaying the original input file in the two text areas as described above.

Domain Description Radix sorting entails grouping number elements in a data structure by each digit. First one groups by 1s; then 10s; then 100s (or the other way around; think little or big endian); and so on. Build a method that effectively models this behavior. You may use the code provided in Lafore, provided you are writing pseudocode, making comments, testing and capturing output and crafting UML. A part of this implementation entails determining the greatest number of digits, to effectively pad smaller elements with zeroes. You may use either an array or a linked structure comprised of nodes. What Will I Submit for Grading?

Buy now Goal:  The goal of this assignment is to gain practical experience with procedural abstraction – how complex functionality can be broken up into different methods and different classes. Problem Overview:  In this assignment, you will continue to implement the component classes of a program for simulating the behaviour of a train management system. Task Overview: In brief, you will write a method for reading in the sections of a track from a file, and you will write a method for allocating routes to trains (so that they don’t collide). If you are a CSSE7023 student you will also be required to write a JUnit4 test suite for testing the track-reading method. More specifically, you must code method read from the TrackReader class and method allocate from the Allocator class that are available in the zip file that accompanies this handout, according to their specifications in those files. If you are a CSSE7023 student, you will also need to complete a systematic and underst...

Buy now Project:    Complete exercise C-10.40 on p. 454 in the textbook.  Read the problem statement carefully.  The authors initially describe the behavior of the java.util.Hashmap class.  As they describe it, the Java implementation of a Hash Map consists of a table (bucket array) of entries.  Each entry consists of a K, V pair with the addition of a next reference that refers to a next entry in the bucket.  In that way, if collisions have occurred and multiple entries/keys hash to the same bucket, they will be arranged in a singly linked list. Data Structure Classes: Your job is to modify the ChainHashMap class, p. 425 of  the textbook to exhibit the same behavior.  You will be modifying the source code of the author’s classes – so the first step will be to copy those files to your eclipse package.  At a minimum I would recommend these: 1. Map.java 2. AbstractMap.java 3. UnsortedTableMap.java 4. AbstractHashMap.java 5. ChainHashM...

In 1903, a small western town--Newcastle, Wyoming--struggles to overcome its remembered violent past of Indian wars and fighting outlaws and enter the new, modern 20th century. Arrayed against this good intent is the fresh reality of vigilante action and a lynching triggered by a gruesome murder and a distrust of civil justice, and ultimately, the final consequential Battle of Lightning Creek. That lesser-known skirmish flared in November of that fateful year as a surprising encore on Wyoming soil pitting townspeople stirred up by a hectoring town father against young Sioux from the Pine Ridge Reservation on a sanctioned fall hunt. Based largely on actual incidents, the events in this book are viewed through the eyes of a precocious adolescent and his adoptive father who, the son of the army's contracted storekeeper at Fort Laramie before the destruction of the buffalo, and partly raised and acculturated by Indians, is the local pariah.

Automatic Testing  This task is available for automatic testing using the name hp-35. You can run the demo using demo hp-35 and you can test your work using try hp-35 <filename. Background The HP-35 was the first scientific hand-held calculator, released in 1972 and an immediate success with engineers and scientists. Amongst other features, it used an unusual way of entering numbers, called RPN. RPN (reverse Polish notation, named for Polish mathematician Jan Lukasiewicz) allows complex calculations to be entered without the use of parentheses. The key difference is that operators are entered after the operands, rather than between them The HP-35 implemented RPN using a stack of 4 registers, referred to as X, Y , Z, and T. The value in the X register is the one shown on the calculator's LED display; the other registers are used for temporary values during calculations. New values are entered into the X register, with existing values "pushed" up the register stack: the ...

Requirements Task is to define a class to represent and manipulate rational numbers (fractions), so that by simply changing the type of n1 and n2 to Rational the program will compute fractional arithmetic expressions such as these: 1/2 + 1/3 // answer: 5/6 1/3 - 1/4 // answer: 1/12 2/3 * 4/5 // answer: 8/15 3/7 / 2/3 // answer: 9/14 Download the file fractions_0.zip, which contains the calculator code and a skeleton version of the Rational class. The class defines (but doesn't fully implement) appropriate constructors to initialise instances of Rational, extract and insert operators for input and output of Rational values, and of course arithmetic operators to compute the results.

Buy now Simple Trip Planner This assignment is inspired by the problem of planning a European holiday by train, making optimal use of travel time. Your aim is to take each of a number of given train trips, e.g. London to Paris. Your journey must include a number of given trips, but may include additional trips to "link up" the cities in the trips you want to take. For simplicity, we assume that trains run frequently, so that you can focus on scheduling a journey that includes all of your specified trips and minimizes time takes to complete the journey (so you don't have to consider time lost waiting around for departures). The trips in your journey can be scheduled in any order, but your journey always starts in London. The aim is to minimize the total journey time, taking into account travel time and a transfer time in each city (except in London at the start of the journey). We assume that all cities can be reached by train directly from any other city, and that the tra...

Bipartite dimension The Territory:  The Memoir of a Friendship in Earliest Iowa is a lighthearted but serious work of fiction in the form of a memoir by one of a pair of generally serious, sometimes comical pioneer settlers in preterritorial and territorial Iowa. Its inspiration is a number of now little-known local and regional events described by prominent longtime resident Benjamin F. Gue in his 1903 History of Iowa, and the setting and details of events and conditions are thoroughly researched and portrayed accurately from scores of books and journal articles, as well as Internet articles. The readership would be anyone interested in a reliable and informative chronicle of Iowa's pioneer past and foundations of the present state and the many issues, large and small, present at that time, and also anyone who likes a rip-roaring story with frequent passages of more and sometimes less subtle humor. Though the work is not lengthy, it portrays virtually every eve...
