Design And Implement Word Guessing Game
Dec 29, 2013I have a project about programing a game in java . In this project you are required to design and implement a word guessing game. In the game, user selects one of the available dictionaries (animals, plants, technical, names, etc. ), and the program randomly chooses one word from that dictionary and displays it by scrambling the letters. The user tries to guess the word while a guess counter starts to count down (lets assume it starts from 5).
While counter counts towards zero, the program chooses -randomly- two misplaced letters and puts them into correct positions to reveal the word more and give the user a hint. However, giving a new hint reduces the total value of the question. Lets say if the initial value of the question is 500 when all letters are scrambled, it reduces to 400 after 1st incorrect guess and hint, then after every incorrect guess it reduces more. You can determine the value of the question by the length of the word. The other details of the game is as follows:
1.You must design at least three classes (for example game, scrambledword, and dictionary).
2.Dictionaries are written in text files. If you design a class for dictionary, it must be constructed by a user chosen category ((animals, plants, technical, names, etc). In the constructor, the dictionary text file corresponding to this category must be opened and read; and words in that dictionary must be read into memory (e.g. String array). You must submit your dictionaries with your code. Do not share dictionaries between friends.
3.The game will record your total points and name in a text file where a hall of fame which has different users and their total points in 10 questions. You can design and implement a class for this.
4.Bonus+5%: Put user interface modules textboxes, buttons, etc Or
a.Use class hierarchy
b.Use of thread and timers and reducing the question value by timer instead of guesses.

View Replies View RelatedDesign And Implement GUI Front End For Computerized Version Of Battleship
Feb 21, 2014Code for implementing a simple computerised version of Battleships has been supplied. Examine the code ensuring that you understand it. The game is played against the computer.
A number of ships (default is 6) are place randomly on a 4 x 4 grid. A ship occupies one square only. The player then guesses the position of a ship. If he/she guesses correctly the ship is HIT and sinks. If the guess is incorrect the player loses a life. The default number of lives is 7. If the location has been guessed already, no lives are lost.
When the game starts, a 4 x 4 grid should be displayed.
The user should be allowed to enter/select a cell location. If the selected cell contains a ship, the ship will be destroyed. If not the player loses a life. The cell should display an appropriate picture, icon or message informing the user of its current state.
The number of lives and number of ships remaining should be displayed.
When the game ends an appropriate message should be shown informing the player whether he/she has won or lost. The positions of the ships should also be shown.
The purpose of this assignment is that students demonstrate an understanding of the Java Swing library and that he/she can navigate and use the API effectively.
Your finished GUI should be both user-friendly and aesthetically pleasing.
Ideally, the user should have the option to play another game, to quit or give up mid-game. You may also wish to include other options such as different levels of difficulty, etc.
JSF :: How To Implement Finger Printing System In Web Application
May 9, 2014I'm currently meddling with javaScript in order to implement a fingerPrinting system in my web application. I've developed the following example in which I can get all the necessarily data:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets">
[Code] ....
Which works correctly.
So when I tried to run it in the following page:
<?xml version='1.0' encoding='UTF-8' ?>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<h:head>
<title>SET - Simulador Econômico Tendências</title>
[Code] .....
It simply won't work!
The function faz() is called and only the first "alert" popup is called, the second one which should show what is returned by dadosDaTela() isn't generated, why is that?
Servlets :: Form Based JAAS - How To Implement Login System Explicitly Outside Container
Jan 30, 2014I have configured form based JAAS in my app. Basically, in web.xml I have declared security constraints on certain jsp page, declared specific roles, login and error pages. So, my login form is:
<form id="loginForm" action="j_security_check" method="post">
<p>
<label for="name">Username</label> <input name="j_username"
id="username" type="text" required/>
[Code] ....
This works fine when some user tries to access some of the pages declared in <security-constraint> tag of web.xml.
Container automatically manages login process, redirects to login page and if login details are valid, gives access to secured page.
Now, how should I implement login system so that user can go to login page (possibly same login form) and log in from there?
Transferring Coordinates From Design Program To Array In Java?
Mar 6, 2015The idea I'd like to present, concerns the correction of "designer" drawings - those done by the design consultants - against "site/construction" drawings - them being used on site by the workers to build the project itself.
This is normally a laborious process, involving being sat at a desk with two large folders, checking each detail and measurement against the design drawing.What I'd like to present is an idea, where the co-ordinates of the design or "mother" drawing, are transferred into a usable Java program, and they could be then used to ensure correct dimensions have been applied by the the sub-contractors in their "construction" drawings.Like I said, this can normally be a process of days for a site engineer to check - process known as "QA, quality assurance".
Basically, I just need to make a presentation of having a genuine interest in Software Design and Development. It could be applied in a range of areas in terms of construction site application - checking drawings, writing up work orders, dig orders etc - but the principle of having the co-ordinates of the mother or "design" drawing scanned into an array in Java as a means to output those site drawings/orders etc, applies to each potential application.
So - in short - and not looking for crystal clear detail, just general pointers - what programs or methods could transfer a plethora of co-ordinates from a design program like Auto-Cad, to a Java program, where I assume I would then be using a program containing a complex series of loops to ensure the correctness of the derived "construction" drawings; derived from the "mother" or designer drawings, that is.

Java Program To Implement A Single Linked List Structure
Jul 27, 2014I'm trying to build a program that contains the ability to:
(1) insert new node at head,
(2) print out contents of the list in order,
(3) remove first node from head,
(4) remove last node from tail,
(5) find a target value,
(6) give total number of occurrences of a target value, and
(7) give total number of items in list.
The areas I'm struggling with implementing are: (
- remove from tail - I know how to find the final node but I can't quite figure out how to set it to null since its initial type is an integer.
- find a target value - how to make the parameters quite workout so the user can simply input an integer value.
- The solution is probably really simple but I can't figure out how to print out the results of these methods when I call them.
public class Node
{
private int data;
private Node link;
// Node Constructor 1
public Node()
{
data = 0;
link = null;

Grading Program - Calculate Final Grade By Using Weighted Scoring System
Nov 29, 2014Many classes calculate a final grade by using a weighted scoring system. For example, "Assignments" might be worth (weighted at) 40% of your final grade. To calculate the portion of the final grade contributed by the Assignments category, the teacher takes the average of all assignments in the category and multiplies it by the weight (40%). So if a student averaged 90% on all assignments, the teacher would take 40% of 90%, or 36 as the weighted average score for the assignment portion of the the final score. The teacher then calculates the weighted average score for each of the other categories (Quizzes, Midterm Exam, Final Exam, etc.), adds them all together to come up with the final score, and assigns a letter grade based on that score.
Write a Java program that allows the teacher to calculate the grade for a student.
Specification :
Prompt the user to enter the Student ID number, first name, last name, and the average score for each of the following categories:
Assignments (worth 50%)
Quizzes (worth 20%)
Midterm Exam (worth 10%)
Final Exam (worth 20%)
Calculate the weighted average score for each category and the total score for the student. Next assign a letter grade as follows:
90 - 100 = A
80 - 89 = B
70 - 79 = C
60 - 69 = D
59 and below = E
Print the results in the following format:
Name: [Last Name], [First Name]
Student ID: [Student ID]
Assignments: [weighted average]
Quizzes: [weighted average]
Midterm Exam: [weighted average]
Final Exam: [weighted average]
Total: [total score]
Final Grade: [letter grade]
Prompt the user to either enter another student or to quit. Continue the process until the user chooses to quit.
I almost done everything but I cant calculate a total score for the student or Assign a letter grade based on the score!!!!
