  • Reading files with Java

    - by sikas
    I would like to know how can I read a file byte by byte then perform some operation every n bytes. for example: Say I have a file of size = 50 bytes, I want to divide it into blocks each of n bytes. Then each block is sent to a function for some operations to be done on those bytes. The blocks are to be created during the read process and sent to the function when the block reaches n bytes so that I don`t use much memory for storing all blocks. I want the output of the function to be written/appended on a new file. This is what I've reached to read, yet I don't know it it is right: fc = new JFileChooser(); File f = fc.getSelectedFile(); FileInputStream in = new FileInputStream(f); byte[] b = new byte[16]; in.read(b); I haven't done anything yet for the write process.

  • Dynamically created jagged "rectangle" array

    - by gagar1n
    In my project I have a lot of code like this: int[][] a = new int[firstDimension][]; for (int i=0; i<firstDimension; i++) { a[i] = new int[secondDimension]; } Types of elements are different. Is there any way of writing a method like createArray(typeof(int), firstDimension, secondDimension); and getting new int[firstDimension][secondDimension]? Once again, type of elements is known only at runtime.

  • C# WTF? Can anyone explain the strange behaviour?

    - by partizan
    Hi, guys. Here is the example with comments: class Program { // first version of structure public struct D1 { public double d; public int f; } // during some changes in code then we got D2 from D1 // Field f type became double while it was int before public struct D2 { public double d; public double f; } static void Main(string[] args) { // Scenario with the first version D1 a = new D1(); D1 b = new D1(); a.f = b.f = 1; a.d = 0.0; b.d = -0.0; bool r1 = a.Equals(b); // gives true, all is ok // The same scenario with the new one D2 c = new D2(); D2 d = new D2(); c.f = d.f = 1; c.d = 0.0; d.d = -0.0; bool r2 = c.Equals(d); // false, oops! this is not the result i've expected for } } So, what do you think about this?

  • Applied style in WPF ignores properties.

    - by Quenton Jones
    Here's the conundrum. In two different places in my application, I use a border with the exact same appearance. In an never-ending fight against code bloat and unmanageable code, I want to define the border's appearance in a style to use when I create the border. Strangely, several of the properties I set are being ignored. Here's the code I use to create the style. Simple enough. Style borderStyle = new Style(typeof(Border)); borderStyle.Setters.Add(new Setter(Border.BorderBrushProperty, Brushes.Black)); borderStyle.Setters.Add(new Setter(Border.BorderThicknessProperty, new Thickness(4))); borderStyle.Setters.Add(new Setter(Border.OpacityProperty, 1.0)); return borderStyle; But when I set the style, the opacity property is left at its original value of 0.7. I have also tried setting the background of the border to a brush I created. It too is ignored. Thanks for any insights you may have.

  • Can't get Dialog hosting a WebView to layout properly

    - by user246114
    Hi, I'm trying to host a webview on a dialog, without a titlebar, but I'm getting odd layout results. Example test: @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); WindowManager wm = (WindowManager)getContext().getSystemService(Context.WINDOW_SERVICE); Display display = wm.getDefaultDisplay(); LinearLayout ll = new LinearLayout(getContext()); ll.setOrientation(LinearLayout.VERTICAL); ll.setLayoutParams(new LayoutParams( LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT)); ll.setMinimumWidth(display.getWidth() - 10); ll.setMinimumHeight(display.getHeight() - 10); WebView wv = new WebView(getContext()); wv.setLayoutParams(new LayoutParams( LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT)); wv.getSettings().setJavaScriptEnabled(true); ll.addView(mWebView); setContentView(ll, new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT)); } the dialog is inflated at startup, but the webview is not visible. If I rotate the device, it becomes visible, and fills the whole parent layout as requested. What is the right way to do this? I simply want a dialog which occupies most of the device screen, and has a WebView on it which fills the entire space. Thanks

  • List.AddRange inline declaration

    - by AJ
    Hello, This may seem an easy question, but not to me, also a search has led to nothing. Up until now the only .net programming I have done is with Delphi Prism. With Prism I can do things like: var l := new List<String>(['A','B','C']); or var l := new List<String>; l.AddRange(['A','B','C']; but can I do a similar thing in C#, or do I have to do it like: var a = new String[] {"A","B","C"}; var l = new List<String>(a); Thanks, AJ

  • Criteria for triggering garbage collection in .Net

    - by Kennet Belenky
    I've come across some curious behavior with regard to garbage collection in .Net. The following program will throw an OutOfMemoryException very quickly (after less than a second on a 32-bit, 2GB machine). The Foo finalizer is never called. class Foo { static Dictionary<Guid, WeakReference> allFoos = new Dictionary<Guid, WeakReference>(); Guid guid = Guid.NewGuid(); byte[] buffer = new byte[1000000]; static Random rand = new Random(); public Foo() { // Uncomment the following line and the program will run forever. // rand.NextBytes(buffer); allFoos[guid] = new WeakReference(this); } ~Foo() { allFoos.Remove(guid); } static public void Main(string args[]) { for (; ; ) { new Foo(); } } } If the rand.nextBytes line is uncommented, it will run ad infinitum, and the Foo finalizer is regularly invoked. Why is that? My best guess is that in the former case, either the CLR or the Windows VMM is lazy about allocating physical memory. The buffer never gets written to, so the physical memory is never used. When the address space runs out, the system crashes. In the latter case, the system runs out of physical memory before it runs out of address space, the GC is triggered and the objects are collected. However, here's the part I don't get. Assuming my theory is correct, why doesn't the GC trigger when the address space runs low? If my theory is incorrect, then what's the real explanation?

  • Why am I getting ClassNotFoundExpection when I have properly imported said class and am looking at it in its directory?

The three jar files (j3dcore, j3dutils, and vecmath) are the essential jar's for my program (or at least I am led to believe according to this official tutorial on J3D For the record I ripped this code almost line from line from this pdf file. jar files are correctly located in referenced locations When I run my Simple program, (java Simple) I am greeted with Exception in thread "main" java.lang.NoClassDefFoundError: javax/media/j3d/Cavas3d Caused by: java.lang.ClassNotFoundExpection: javax.media.j3d.Canvas3D Currently I am staring directly at this Canvas3D.class that is located within j3dcore.jar\javax\media\j3d\ wtfisthis.jpg Here is the source code: //First java3D Program import java.applet.Applet; import java.awt.BorderLayout; import java.awt.Frame; import java.awt.event.*; import com.sun.j3d.utils.applet.MainFrame; import com.sun.j3d.utils.universe.*; import com.sun.j3d.utils.geometry.ColorCube; import javax.media.j3d.*; import javax.vecmath.*; import java.awt.GraphicsConfiguration; public class Simple extends Applet { public Simple() { setLayout(new BorderLayout()); GraphicsConfiguration config = SimpleUniverse.getPreferredConfiguration(); Canvas3D canvas3D = new Canvas3D(config); add("Center", canvas3D); BranchGroup scene = createSceneGraph(); scene.compile(); // SimpleUniverse is a Convenience Utility class SimpleUniverse simpleU = new SimpleUniverse(canvas3D); // This moves the ViewPlatform back a bit so the // objects in the scene can be viewed. simpleU.getViewingPlatform().setNominalViewingTransform(); simpleU.addBranchGraph(scene); } // end of HelloJava3Da (constructor) public BranchGroup createSceneGraph() { // Create the root of the branch graph BranchGroup objRoot = new BranchGroup(); // Create a simple shape leaf node, add it to the scene graph. // ColorCube is a Convenience Utility class objRoot.addChild(new ColorCube(0.4)); return objRoot; } public static void main(String args[]){ Simple world = new Simple(); } }` Did I import correctly? Did I incorrectly reference my jar files in my Javac statement? If I clearly see Canvas3D within its correct directory why cant java find it?

If the compiler is getting confused how do I specify where to find that exact class when referencing it within my source code?

  • How to write a variable with input ?

    - by ldigas
    the title is somewhat vague, so let me explain I'm trying to ask the user for a value of some variable, but at the same time, showing him the last value used (at the termination of the program, the values are saved to a file, and loaded at the start of the program). Something like this: Enter new radius value (R=12.6) : ... user enters 12.7 ... Enter new pi value (pi=3.14) : Enter new height value (h=30.0) : Usually I would write the first one with write statement, then read the new one (in fortran, for example). In matlab however, I don't know how to write something out with input statement. Are there some other statements for getting input ? All your thoughts on the subject appreciated.

  • Netbeans braces placement issue

    Hi there, I'm trying to get Netbeans PHP to let me write braces in a new line instead of the same line, I mean like this: if($something == TRUE) { // some code here } However, when I write if($something == TRUE) then hit enter, Netbeans places the cursor incorrectly in the new line, like this: if($something == TRUE) { // some code here } I've already changed the braces placement option to be "New Line", but this still doesn't work properly. Any idea how I can fix this? Appreciate your help

  • Automatic program update and Windows 7

    - by Mmarquee
    Hi We have a suite of programs that check for new versions at startup, and then download new versions to run if required. This is obviously a problem in Windows 7, when it is locked down as a 'standard user', as they can't write to the c:\program files directory and below. Anyone seen a example of an application that gets around with issue ? Our applications are written in Delphi, but an example in any language would be useful. Thanks in advance Update: We already have a system for determing whether a new version exists, the only problem is the download and install (if required), as this requires elevation. I can't think of a way that doesn't require an elevation prompt, or our users to reduce their security settings. Update 2 : I've asked a subsequent question, rather than adding a new one here

Within the MainViewModel I spread those services to other ViewModels via constructor parameter passing. Should I use any DI framework for the services in the App class? If yes whats the benefit of resolving the services instead of just creating the instance manually... ?

  • Instantiating class by string using PHP 5.3 namespaces

    - by Kevin
    I can't get around an issue instantiating a new class by using a string variable and PHP 5.3. namespaces. For example, this works; $class = 'Reflection'; $object = new $class(); However, this does not; $class = '\Application\Log\MyClass'; $object = new $class(); A fatal error gets thrown stating the class cannot be found. However it obviously can be instantiated if using the FQN i.e.; $object = new \Application\Log\MyClass; I've found this to be aparrent on PHP 5.3.2-1 but not not in later versions. Is there a work around for this?
