Philosophical Design Questions for OOP-Tetris -

-

You are writing a Tetris program in Java. Regarding the following aspects, how do you set up your class design?

  • Piece Class: An piece of an internal array that determines the size of the piece, vs. seven piece Squares, one for each piece, they are all sub-squares of a normal Paes class.
  • Piece Class Representation: Create an array of 4 examples of a <4> block , represent a square of one piece, and each < It has its place on the board in the code> block (in the graphical coordinates) vs. 4x4 array where null means that there is no block there, and the location is determined
  • Location: In the block the block or on the board code> arrays make its place versus. Know the locations of the piece and boards to the blocks which include them.
  • Generating a piece: is a static method of the grinding class getRandomPiece , or a PieceFactory , on which you Create an example Zenerlandam Method method
  • Regulating the current piece: Use the e> proxy pattern, so that it needs access, everything that just proxy , Or the getCurrentPiece method is on the board class and at any time calls you want to do something with the current piece.

This is not a homework. I just want to differentiate my introduction to the CS course from college and I want to see what people generally believe. What would be thought of "good" OOP designs? Ignore the fact that this is an introduction to the course - how will you do this?

First of all, I will not give a subclass of piece class because it Unnecessary fragment class without using heritage should be able to describe any shape. IMHO, this is not exactly what part was created for and it just complicates things.

Second, I do not store the x / y coordinate in the blocks objects because it has two blocks in the same place fragment class block object Hold a grid (i.e. 2D array). The X / Y coordinates will be indexed to 2D arrays.

To get a random piece, for Static Method vs. Factory Object, I want to go to the simple fact with the Factory Object that junk can be junky for factory object testing.

I will treat the board as a large piece object board class as a member variable, large piece The current piece is played, and the current piece can be played, and the next piece can be played, the structure is used to avoid this heritage.

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...

php - Multiple Select with Explode: only returns the word "Array" -

By using Wordpress I have created a multiple selection box so that users can select categories to exclude. When the page is initially loaded, I see my predefined default option. However, when I select a new value and I save ... I only see the word "Array" and have not chosen anything else? & lt; Class = "amultiple" id = "& lt; php echo $ value ['id'] ;? gt;" name = "& gt; php echo $ value ['id'] ;; gt; []" Multiple = "multiple" size = "8" & gt; & Lt ;?

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som...
