• Web Application

  - by Raydon

  I'm designing a web application. I was wondering if it was feasible to design a php front end (using some php framework e.g. CakePHP), which stores and retrieves data to display to the user. Then develop a java backend which listens to the database for changes, and depending on what was changed, performs some actions and updates the database. Any thoughts on this type of implementation would be appreciated.

• The fundamentals of Hash tables?

  - by kylex

  I'm quite confused about the basic concepts of a Hash table. If I were to code a hash how would I even begin? What is the difference between a Hash table and just a normal array? Basically if someone answered this question I think all my questions would be answered: If I had 100 randomly generated numbers (as keys), how would I implement a hash table and why would that be advantageous over an array? Psuedo-code or Java would be appreciated as a learning tool...

• Can I move another program's window to the front of focus?

  - by TwentyMiles

  I am interacting with a third party application using it's API, and would like to move it to the front of focus (so that it is on top of all other open windows) when a user performs a certain action. While I can move my application up and down in the hierarchy pretty easily, there doesn't appear to be a way to interact with other windows. Is it possible to move another program's window to front with Java?

  I've got a string: public://imageifarm/3600.jpg How can I extract the imageifarm/3600.jpg Part out using android? What I've tried so far: URL drupalQuestionNodeImageURI = new URL("public://imageifarm/3600.jpg"); Log.d("TAG", drupalQuestionNodeImageURI.getPath()); but it throws this exception: 09-16 17:24:39.992: W/System.err(3763): java.net.MalformedURLException: Unknown protocol: public How can I solve this? I know I can use regular expressions but that seems to defeat the purpose of URL(URI) in this case.

• Dependency Injection: What's wrong with good old-fashioned refactoring?

  - by Chuck

  DI creates an extra layer of abstraction so that if your implementation class ever changes you can simply plug in a different class with the same interface. But why not simply refactor when you want to use a different implementation class? Other languages like Python and Ruby work fine this way. Why not Java?

• Why do I have to pay for something that I'm not using?

  - by Knowing me knowing you

  Guys just finished reading one of my college books about threads in Java and I was informed that lock - what ever it is, is in Object class. So it looks like even though I'm not using threaded classes my objects will be heavier because of that? Don't you think that it's a bit annoying and unfair to expect from anyone to pay for something s/he have not intention of using? Thanks

• Use the right tool for the job: embedded programming

  - by EmbeddedProg

  I'm interested in programming languages well suited for embedded programming. In particular: Is it possible to program embedded systems in C++? Or is it better to use pure C? Or is C++ OK only if some features of the language (e.g. RTTI, exceptions and templates) are excluded? What about Java in this domain? Thanks.

• Can I Define Exceptions to Eclipse cleanup rules?

  - by Henrik Paul

  Most often the cleanup rules (Preferences Java Code Style Clean Up) in Eclipse work perfectly and create nice-looking code. But sometimes, especially with comments and concatenated string snippets (like inline SQL queries), the cleanup just messes things up, and destroys my formatting. Is there a way to say to Eclipse "Don't touch this block of text! I have formatted it just the way I like, and you would make it just less readable"?
