Polymorphic Containers And Text Processing In Java?
May 9, 2014It seems we have abandoned Dice/Die(s), and are now working on something completely foreign. I don't even have a code to start with because I haven't the faintest clue what is going on here (no notes given on this topic, as usual). We are given 4 half-written programs to work with.
The instructions are:
"Examine the FormLetterEntry abstract class, and create the two derived classesTextEntry and DataItemEntry. Be sure to implement all the abstract methods in each derived class."
This is the code we were given:
package homework5;
import java.util.Properties;
/**
* Abstract class representing the entries in a form letter.
**/
public abstract class FormLetterEntry {
/**
* Retrieve the template string for this entry
* @return the value of this entry in a template
**/
[code].....
I understand (and correct me if I am wrong) that a derived class is a class that is created from a base class via inheritance. What I don't see are any notes on how to write a derived class. I see some notes online on how to do so, but they don't fit with what he's written above. What he means by "Be sure to implement all the abstract methods in each derived class."

Text Files And Word Processing Software
Sep 1, 2007Why is it simple for a word processing software (one that reads number of words, words greater that x characters etc) to deal with text file(.txt) and not with a doc file (.doc) file?? Is there any special requirements or what are the points taken into consideration while developing the software for a .doc file?

How To Implement Collections Binary Search Method On ArrayList Of Custom Objects
May 11, 2012I'm doubted regarding the implementation of Collections.binarySearch() method on an ArrayList of objects of a custom class Movie.
Here is the movie class :
public class Movie implements Comparable<Movie> {
String movieName;
String rating;
String director;
String theme;
[Code] .....
The sort/binarySearch in searchByMovieName function is done with natural sorting (and Comparable Interface in Movie class). I mean no comparators involved here. And the comparator that I used for sorting/binarySearching on Movies Director attribute in searchByMovieDirector function is :
public class MovieDirectorComparator implements Comparator<Movie> {
public int compare(Movie movie1, Movie movie2) {
return movie1.getDirector().compareToIgnoreCase(movie2.getDirector());
}
}
But I was not able to implement binarySearch ?? How to implement the binarySearch here. I have google to see only binarySearch working on Arrays or probably ArrayList of String only, but not on ArrayList of custom objects.

How To Implement Basic Text-based Rpg Game In A Website
Jan 13, 2015I started programming some time ago and i recently finished a game i've been programming in Java just to get used to the code. The game is a simple text-based RPG where almost everything is random except the character movement.
I've been thinking about learning HTML and CSS because i'm really interested in building webpages. I have no one to ask this question so here i am.
Is there a way to implement my game in a webpage?
I imagine a black window exactly like a classic OS terminal where the text is streamed and the user can play the game with keyboard inputs. I made the game with 5 different classes, i used Eclipse and i have my project there. Should i use a service like Github to share works like this one?
EJB / EE :: Long Running Task Processing In Java
Feb 18, 2014I want to develop a Java EE application for the following scenario.

I checked what are the possibles ways I could achieve this but couldn't get a clear idea. I heard about JMS, Work Manager API and servlet asynchronous processing. But still not sure what to use and how to use.I'm not very much familiar with EJB.

View Replies View RelatedJava Servlet :: Implement Session Timeout For Users
Dec 7, 2012Coding a web application using Java 6. Try to implement the session timeout for users.
In the web.xml, I added:
<session-config>
<session-timeout>480</session-timeout> <!-- jsp will expire in 8 hours -->
</session-config>
Now, during the runtime, if a user does not touch the jsp page for 8 hours (after the user has signed in), the session timeout mechanism will kick in. At that point, the server side will automatically execute:
rd = req.getRequestDispatcher("/signin.jsp");
So that the user will have to re-sign in, before continue the work.
How can I achieve this goal?
