This might be a really trivial question, but I've been writing Java programs at my school. But I just found out that I can create websites with Java as well. How can I do that? Any good books/tutorials for that? Also, I know about PHP, which is better for Web development? Also, when using PHP, MySQL comes into picture and while writing J...

I used log4j in a java program. I initialized it with : BasicConfigurator.configure(); // logger configuration try { logger.setLevel(Level.DEBUG); } catch (Exception e) { System.out.println("Logfile not found"); } But, during the execution of the program i get 3 log statements instead of one. For example, 3 lines 1047 [mai...

This is my main class: p...

I am looking to use a natural language parsing library for a simple chat bot. I can get the Parts of Speech tags, but I always wonder. What do you do with the POS.

I am looking to start fiddling around with Java development in my free time (professionally a .NET developer) and I am curious as to what the community feels is their preferred development environment. Items that could be listed: IDE Plugins Tools Utilities Source/Version Control Libraries Books Blogs Anything ...
i'm looking for a fast way to determine the area of intersection between a rectangle and a circle (I need to do millions of these calculations) A specific property is that in all cases the circle and rectangle always have 2 points of intersection. Java lib would be awesome! Thanks, Britske ...

Do you know how to convert (save) HTML to an image? Any format is acceptable: jpg, png, ... I tried this code but it does not correctly convert images from HTML (<img> tag). A solution in Java would be preferred; however, I would appreciation any approach. ...
I'm trying to show the famous mouth opening/closing animation of the pacman character in a throwaway pacman game I'm making to teach myself game programming. What I'm doing is drawing the open mouth image, then redrawing the closed mouth image at the exact same (x/y) location. But this doesn't work, and I just see the closed mouth anima...
So I'm building the pacman game in Java to teach myself game programming. I have the basic game window with the pacman sprite and the ghost sprites drawn, the pacman moves with the arrow keys, doesn't move beyond the walls of the window, etc. Now I'm trying to build the maze, as in this picture: Without giving me the direct/complete ...
I am curious to know how Reflection and Remoting in .net work internally. I also hear that .net can use remoting to communicate with applications written in other languages (such as Java). How does that work? This is probably a large question so an answer that briefly touches upon each question is reasonable. ...
I'm building a pacman game. Basically, I want to have a map representation of this window consisting of blocks/tiles. Then as the pacman character/ghost moves i would change their position on the map to represent what's on the screen, and use that for collision detection etc. How can I build this map, especially since the screen is made...

And is there any function to check if a given element/index exists/has been set? ...
I'm planning to use jBCrypt for password hashing in a new web application, as it is supposed to be the best from what I've read. As I haven't used it before I'm looking into if there is any reason not to use it. I have this: I haven't found it in the Maven repository (searched for jbcrypt and bcrypt at mvnrepository.org) which is a do...
Sometimes, you want to test a class method and you want to do an expectation on a call of a super class method. I did not found a way to do this expectation in java using easymock or jmock (and I think it is not possible). There is a (relative) clean solution, to create a delegate with the super class method logic and then set expectati...
