The fact that Java has a HashMap class means that no Java programmer has to write an implementation of hash tables from scratch -- unless, of course, you are a computer science student. For this exercise, you should write a hash table in which both the keys and the values are of type String. (This is not an exercise in generic programming; do not try to write a generic class.) Write an implementation of hash tables from scratch. Define the following methods: get(key), put(key,value), remove(key), containsKey(key), and size(). Remember that every object, obj, has a method obj.hashCode() that can be used for computing a hash code for the object, so at least you don't have to define your own hash function. Do not use any of Java's built-in generic types; create your own linked lists using nodes as covered in section 9.2.2 of the textbook. However, you do not have to worry about increasing the size of the table when it becomes too full. Get your project now  Buy now

Purposes of this project: get you started using basic Java constructs, including: The use of Scanner to get user input Declarations, assignment statements, if and while statements. System.out.print and println methods. General idea: Simulate the operation of a Coke machine. This machine offers Coke, Coke Zero, and Caffeine-free Diet Coke. All drinks cost $1 (100 cents). The machine does not take dollar bills or pennies, but it does take nickels, dimes, and quarters. When enough money has been entered, a drink may be selected, and any change is returned (the specific coins are listed).Only coins in denominations of 5, 10, and 25 cents are accepted. Any other denomination (33 cents, 50 cents, etc.) is rejected and returned. More than one drink may be purchased (that is, the program doesn't quit after selling one drink).There is no way to turn off the coke machine. When you run the program from within Eclipse, you can stop it by pressing the red square. Example: Here is an ex...

(Manipulating a Stream<Invoice ) Use the class Invoice to create a List of Invoice objects. Use the sample data shown in the Fig. Class Invoice includes four properties PartNumber (type int ), PartDescription (type String ), Quantity of the item being purchased (type int ) and Price (type double ). Perform the following queries on the List of Invoice objects and display the results: Use lambdas and streams to sort the Invoice objects by PartDescription , then display the results. Use lambdas and streams to sort the Invoice objects by Price , then display the results. Use lambdas and streams to map each Invoice to its PartDescription and Quantity , sort the results by Quantity , then display the results. Use lambdas and streams to map each Invoice to its PartDescription and the value of the Invoice (i.e., Quantity * Price ). Order the results by Invoice value. Modify Part (d) to select the Invoice values in the range $200 to $500. Get your solution now  Buy no...

In this project, you will implement an airplane seat reservation system. An airplane has two classes of service (first and economy). Each class has a sequence of seat rows. The following figure shows the seat chart of the airplane. A reservation request has one of two forms. One form is that an individual passenger request consists of the passenger name, a class of service, and a seat preference such as W(indow), C(enter), or A(aisle) seats. The reservation program either finds a matching seat (the search may start from the first row of the class.) and reserves it for the passenger, or it fails if no matching seat is available. (For example, if the user's preference is a W(indow) seat and none is available, tell the user no Window seat is available and ask for another seat preference.) The other form is that a group request consists of a list of passenger names and a class of service. (Groups cannot specify a seat preference). The reservation program finds the first row of adjace...

Question 1 Write a Java program to compose a random sequence of 10 case-sensitive letters. Allowable letters are: C,D,E,F,G,A,B,c,d,e,f,g,a,b. Assign random values to each letter. Allowable values are 4,3.5,3,2.5,2,1.5,1,0.5. Display a comma separated list of each generated letter followed by its assigned value. Do not include a space between the letter and its assigned value. Use an array as part of the solution to this question. Question 2 Write a program that prompts the user for a character in the range of a-z (inclusive) and 3 integers in the range of 1-9 (inclusive). The program should convert the character into lowercase and get its numeric equivalent (where a is 1, b is 2 … z is 26) and multiply the numeric equivalent by the sum of the integer inputs. The program should print the inputs and the total in CSV format to a file. The first line in the file should contain headings. The second line should contain the values. Each output should be separated by the | symbol. The ...

Introduction The purpose of the project is to try in practice the use of recursion and object-oriented program design. Please make sure to read this entire note before starting your work. Pay close attention to the sections on deadlines, deliverables, and exam rules. The problem Your task in this part of the project is to write a solver for Sudoku puzzles. Sudoku puzzles are a kind of crossword puzzles with numbers where the following two conditions have to be met: In each row or column, the nine numbers have to be from the set [1,2,3,4,5,6,7,8,9] and they must all be different. For each of the nine non-overlapping 3x3 blocks, the nine numbers have to be from the set [1,2,3,4,5,6,7,8,9] and they must all be different. The following two figures show a Sudoku puzzle and its solution. The input The input of your program, the Sudoku puzzles, is given in text files. More specifically, they are represented as nine lines of nine characters separated by spaces. The characters can b...

Tape for a Turing Machine (Doubly-linked List) Short exercise in which you will code part of an existing project. In this case, you will be working with a doubly-linked list. To make this topic more interesting, the list that you work on will be part of a Turing Machine. A Turing Machine is a kind of very simple, abstract computing device that was introduced in the 1930's by Alan Turing as a way of studying computation and its limitations. The classes that you need for the lab are in a package named turing. You will define a new class named Tape in this package. You can find the Java source in the code directory. You should copy this directory into an Eclipse project. There will be errors, since the existing classes depend on the Tape class, which you have not yet written. Don't forget the Javadoc comments. A Class for Turing Machine Tapes A Turing machine works on a "tape" that is used for both input and output. The tape is made up of little squares called cell...

For this lab, you will do some work on a GUI program. Most of the work is related to actions, buttons, menus, and toolbars.When you turn in your work for this lab, you should also turn in an executable jar file of your program, in addition to all the files from your Eclipse project. See the last section on this page for information about how to create executable jar files. To begin the lab, create a new project in Eclipse and copy-and-paste both directories – guidemo and resources -- from the code directory into your Eclipse project. The guidemo directory is a package that contains the Java code of the program. The resources directory has several sub-directories that contain image and sound resources used by the program. You will be working only on the code in the guidemo package. The code directory also contains an executable jar file of the completed program, GuiDemoComplete.jar. You can run this jar file to see how the program should look when it's done. In the incomplete so...

Firstly, this worksheet is one of the worksheets from which your laboratory worksheets portfolio of work will be assessed. This worksheet is about empirically evaluating how scalable a number of single population heuristic search methods are at solving the Travelling Salesman Problem (TSP) when applied to a number of different sized problems. The aim is to evaluate and demonstrate how well each of the methods performs as the size of the problem increases. The overall objective of this worksheet is to produce; present and report on, a Java program that is capable of solutions the TSP on a number of different sized problems using a number of different heuristic search algorithms (see below). Solving the TSP Problem The Travelling Salesman problem (TSP) has been described fully in the lectures. The purpose of this worksheet is to: 1) Implement a number of the algorithms (listed below) to solve the TSP 2) Compare the algorithms on a number of different sized datasets 3) Report o...

The 8-puzzle problem In this project you will implement a solution to the 8-puzzle by state-space search, using the search engine described in the lectures, and experiment with search strategies. 2. What you must do 2.1 Implementing 8-puzzle search In the search2 folder in the Java download on the COM1005/2007 MOLE site is the code for the simple search engine and for Jugs problems. Note that you may have to recompile the code for your version of Java. Following the instructions in section 2.9 of the lecture notes, write classes to implement a state-space search for 8-puzzle problems. You should not need to change the code for the search engine except perhaps to control how much it prints as a search proceeds, and to stop the search after a given number of iterations (in an 8-puzzle the search tree can become large). Test your implementation with breadth-first searches for the following initial con- figurations and the same goal state as above: 2.2 Experimenting with ...
