  • filling array gradually with data from user

    - by neville
    I'm trying to fill an array with words inputted by user. Each word must be one letter longer than previous and one letter shorter than next one. Their length is equal to table row index, counting from 2. Words will finally create a one sided pyramid, like : A AB ABC ABCD Scanner sc = new Scanner(System.in); System.out.println("Give the height of array: "); String[] words = new String[height]; for(int i=2; i<height+2; i++){ System.out.println("Give word with "+i+" letters."); words[i-2] = sc.next(); while( words[i-2].length()>i-2 || words[i-2].length()<words[i-3].length() ){ words[i-2] = sc.next(); } } Currently the while loop doesn't influence scanner at all :/

  • How to get contacts in order of their upcoming birthdays?

    - by Pentium10
    I have code to read contact details and to read birthdays. But how do I get a list of contacts in order of their upcoming birthday? For a single contact identified by id, I get details and birthday like this: Cursor c = null; try { Uri uri = ContentUris.withAppendedId( ContactsContract.Contacts.CONTENT_URI, id); c = ctx.getContentResolver().query(uri, null, null, null, null); if (c != null) { if (c.moveToFirst()) { DatabaseUtils.cursorRowToContentValues(c, data); } } c.close(); // read birthday c = ctx.getContentResolver() .query( Data.CONTENT_URI, new String[] { Event.DATA }, Data.CONTACT_ID + "=" + id + " AND " + Data.MIMETYPE + "= '" + Event.CONTENT_ITEM_TYPE + "' AND " + Event.TYPE + "=" + Event.TYPE_BIRTHDAY, null, Data.DISPLAY_NAME); if (c != null) { try { if (c.moveToFirst()) { this.setBirthday(c.getString(0)); } } finally { c.close(); } } return super.load(id); } catch (Exception e) { Log.v(TAG(), e.getMessage(), e); e.printStackTrace(); return false; } finally { if (c != null) c.close(); } and the code to read all contacts is: public Cursor getList() { // Get the base URI for the People table in the Contacts content // provider. Uri contacts = ContactsContract.Contacts.CONTENT_URI; // Make the query. ContentResolver cr = ctx.getContentResolver(); // Form an array specifying which columns to return. String[] projection = new String[] { ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME }; Cursor managedCursor = cr.query(contacts, projection, null, null, ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC"); return managedCursor; }

  • Computational geometry: find where the triangle is after rotation, translation or reflection on a mi

    - by newba
    I have a small contest problem in which is given a set of points, in 2D, that form a triangle. This triangle may be subject to an arbitrary rotation, may be subject to an arbitrary translation (both in the 2D plane) and may be subject to a reflection on a mirror, but its dimensions were kept unchanged. Then, they give me a set of points in the plane, and I have to find 3 points that form my triangle after one or more of those geometric operations. Example: 5 15 8 5 20 10 6 5 17 5 20 20 5 10 5 15 20 15 10 I bet that have to apply some known algorithm, but I don't know which. The most common are: convex hull, sweep plane, triangulation, etc. Can someone give a tip? I don't need the code, only a push, please!

  • Problems with matching emails with regex

    - by Gandalf StormCrow
    Hello, I'm trying to match an email address here is what I've come up with so far : String text = "[email protected]"; String regex = "(\\w+)@{1}(\\w+){2,}\\.{1}\\w{2,4}"; This however works with following cases : [email protected] [email protected] [email protected] So it matches any alphanumeric character repeated once or more that comes before one @ followed by any alphanumeric character repeated at least two times(which is minimal characters for any domain name) followed by one .(dot) and followed by any alphanumeric character repeated at least 2 times and at most 4 times(because there are domains such as .us or .mobi). This expression however does not work with emails such as : [email protected] [email protected] [email protected] [email protected] etc as many subdomains or [email protected] [email protected] [email protected] [email protected] I've just started to learn regex and I found interesting to try to solve problems such as these by using regex .. not partially but for each case, any help would be much appriciated. Thank you

  • How to test IO code in JUnit?

    - by add
    I'm want to test two services: service which builds file name service which writes some data into file provided by 1st service In first i'm building some complex file structure (just for example {user}/{date}/{time}/{generatedId}.bin) In second i'm writing data to the file passed by first service (1st service calls 2nd service) How can I test both services using mocks without making any real IO interractions? Just for example: 1st service: public class DefaultLogService implements LogService { public void log(SomeComplexData data) { serializer.write(new FileOutputStream(buildComplexFileStructure()), data); or serializer.write(buildComplexFileStructure(), data); or serializer.write(new GenericInputEntity(buildComplexFileStructure()), data); } private ComplextDataSerializer serializer; // mocked in tests } 2nd service: public class DefaultComplexDataSerializer implements ComplexDataSerializer { void write(InputStream stream, SomeComplexData data) {...} or void write(File file, SomeCompexData data) {...} or void write(GenericInputEntity entity, SomeComplexData data) {...} } In first case i need to pass FileOutputStream which will create a file (i.e. i can't test 1st service) In second case i need to pass File. What can i do in 2nd service test if I need to test data which will be written to specified file? (i can't test 2nd service) In third case i think i need some generic IO object which will wrap File. Maybe there is some ready-to-use solution for this purpose?

  • Publishing selection in eclipse RCP

    - by Stuart
    I'm writing an RCP application plug-in. I want to make a set of objects the global selection from a IHandler but this can be triggered from other views out of my control - it is possible that these do not have an ISelectionProvider. Is it possible to publish a selection to the eclipse selection service without going through some view site?

  • EJB3 Transaction Propogation

    - by Matt S.
    I have a stateless bean something like: @Stateless public class MyStatelessBean implements MyStatelessLocal, MyStatelessRemote { @PersistenceContext(unitName="myPC") private EntityManager mgr; @TransationAttribute(TransactionAttributeType.SUPPORTED) public void processObjects(List<Object> objs) { // this method just processes the data; no need for a transaction for(Object obj : objs) { this.process(obj); } } @TransationAttribute(TransactionAttributeType.REQUIRES_NEW) public void process(Object obj) { // do some work with obj that must be in the scope of a transaction this.mgr.merge(obj); // ... this.mgr.merge(obj); // ... this.mgr.flush(); } } The typically usage then is the client would call processObjects(...), which doesn't actually interact with the entity manager. It does what it needs to do and calls process(...) individually for each object to process. The duration of process(...) is relatively short, but processObjects(...) could take a very long time to run through everything. Therefore I don't want it to maintain an open transaction. I do need the individual process(...) operations to operate within their own transaction. This should be a new transaction for every call. Lastly I'd like to keep the option open for the client to call process(...) directly. I've tried a number of different transaction types: never, not supported, supported (on processObjects) and required, requires new (on process) but I get TransactionRequiredException every time merge() is called. I've been able to make it work by splitting up the methods into two different beans: @Stateless @TransationAttribute(TransactionAttributeType.NOT_SUPPORTED) public class MyStatelessBean1 implements MyStatelessLocal1, MyStatelessRemote1 { @EJB private MyStatelessBean2 myBean2; public void processObjects(List<Object> objs) { // this method just processes the data; no need for a transaction for(Object obj : objs) { this.myBean2.process(obj); } } } @Stateless public class MyStatelessBean2 implements MyStatelessLocal2, MyStatelessRemote2 { @PersistenceContext(unitName="myPC") private EntityManager mgr; @TransationAttribute(TransactionAttributeType.REQUIRES_NEW) public void process(Object obj) { // do some work with obj that must be in the scope of a transaction this.mgr.merge(obj); // ... this.mgr.merge(obj); // ... this.mgr.flush(); } } but I'm still curious if it's possible to accomplish this in one class. It looks to me like the transaction manager only operates at the bean level, even when individual methods are given more specific annotations. So if I mark one method in a way to prevent the transaction from starting calling other methods within that same instance will also not create a transaction, no matter how they're marked? I'm using JBoss Application Server 4.2.1.GA, but non-specific answers are welcome / preferred.

  • Need help receiving ByteArray data

    - by k80sg
    Hi folks, I am trying to receive byte array data from a machine. It sends out 3 different types of data structure each with different number of fields which consist of mostly int and a few floats, and byte sizes, the first being 320 bytes, 420 for the second type and 560 for the third. When the sending program is launched, it fires all 3 types of data simultaneouly with an interval of 1 sec. Example: Sending order: Pack1 - 320 bytes 1 sec later Pack2 - 420 bytes 1 sec later Pack3 - 560 bytes 1 sec later Pack1 - 320 bytes ... .. . How do I check the incoming byte size before passing it to: byte[] handsize = new byte[bytesize]; as the data I receive are all out of order, for instance using the following the read all int: System.out.println("Reading data in int format:" + " " + datainput.readInt()); I get many different sets of values whenever I run my prog although with some valid field data but they are all over the place. I am not too sure how exactly should I do it but I tried the following and apparently my data fields are not receiving in correct sequence: BufferedInputStream bais = new BufferedInputStream(requestSocket.getInputStream()); DataInputStream datainput = new DataInputStream(bais); byte[] handsize = new byte[560]; datainput.readFully(handsize); int n = 0; int intByte[] = new int[140]; for (int i = 0; i < 140 ; i++) { System.out.println("Reading data in int format:" + " " + datainput.readInt()); intByte[n] = datainput.readInt(); n = n + 1; System.out.println("The value in array is:" + intByte[0]); System.out.println("The value in array is:" + intByte[1]); System.out.println("The value in array is:" + intByte[2]); System.out.println("The value in array is:" + intByte[3]); Also from the above code, the order of the values printed out with System.out.println("Reading data in int format:" + " " + datainput.readInt()); and System.out.println("The value in array is:" + intByte[0]); System.out.println("The value in array is:" + intByte[1]); are different. Any help will be appreciated. Thanks

    Hello! I am using some home replacement that allow me to hide the notification Bar and that's something I really like. All the informations can be replaced by some widgets, but I would like to display the notifications too. As I already developed some applications, I would like to know if there is a command line that allow an application to get all the notifications. I plan to add this to a widget or a toast. Thank a lot for any clue or help.

  • In wicket, combine wicket:link with IAuthorizationStrategy

    - by seanizer
    Hi everybody. I use an IAuthorizationStrategy in wicket to limit access to certain pages. However, I also use html menus like this one: <div class="siteMenu"> <wicket:link> <a href="Page1.html" class="siteMenuLink"> <wicket:message key="pages.page1.title" /> </a> <a href="Page2.html" class="siteMenuLink"> <wicket:message key="pages.page2.title" /> </a> <a href="Page3.html" class="siteMenuLink"> <wicket:message key="pages.page3.title" /> </a> </wicket:link> </div> , that are automatically picked up and expanded using the wicket:link mechanism (like here: http://wicket.apache.org/examplenavomatic.html ). However, the IAuthorizationStrategy may not allow one or more of these target pages, so I may end up either with lots of links that lead to "permission denied" pages or lots of deactivated links (i.e. em tags or the like), neither of which is pretty. I could of course write an IComponentInstantiationListener that checks all BookmarkableLinks to see whether their target is accessible through the IAuthorizationStrategy and renders them invisible otherwise, but I wonder if there is an out-of-the-box solution to this problem. For clarification: I only use the isInstantiationAuthorized() method of IAuthorizationStrategy.

  • When the request xml with extra elements, return Unmarshalling Error in CXF 2.2.7

    The wsdl as following: <xs:complexType name="GetCompositionDto" <xs:complexContent <xs:extension base="tns:baseDto" <xs:sequence <xs:element minOccurs="0" name="itemCode" type="xs:string"/ <xs:element minOccurs="0" name="compositionVersion" type="xs:string"/ </xs:sequence </xs:extension </xs:complexContent </xs:complexType After I updated the CXF the jars. from cxf-2.1.4, jaxb-Impl-2.1.9, jaxb-xjc-2.1.9 To cxf-2.2.7, jaxb-Impl-2.1.12, jaxb-xjc-2.1.12. When I request the XML with following: <itemCodeaa</itemCode <compositionVersionbb</compositionVersion <h22</h --- extra element Displays Errors: Unmarshalling Error: unexpected element (uri:"", local:"h"). Expected elements are <{}itemCode,<{}compositionVersion I know the 'h' doesn't map the element in WSDL. But It's OK in the cxf-2.1.4 version. How can i solve this problem? thanks.

  • How to implement SAML SSO

    - by A_M
    How is SAML SSO typically implemented? I've read this about using SAML with Google Apps, and the wikipedia entry on SAML. The wikipedia entry talks about responding with forms containing details of the SAMLRequest and SAMLResponse. Does this mean that the user has to physically submit the form in order to proceed with the single sign on? The google entry talks about using redirects, which seems more seemless to me. However, it also talks about using a form for the response which the user must submit (although it does talk about using JavaScript to automatically submit the form). Is this the standard way of doing this? Using redirects and JavaScript for form submission? Does anyone know of any other good resources about how to go about implementing SSO between a Windows Domain and a J2EE web application. The web application is on a separate network/domain. My client wants to use CA Siteminder (with SAML).

  • Jackson object mapping - map incoming JSON field to protected property in base class

    - by Pete
    We use Jersey/Jackson for our REST application. Incoming JSON strings get mapped to the @Entity objects in the backend by Jackson to be persisted. The problem arises from the base class that we use for all entities. It has a protected id property, which we want to exchange via REST as well so that when we send an object that has dependencies, hibernate will automatically fetch these dependencies by their ids. Howevery, Jackson does not access the setter, even if we override it in the subclass to be public. We also tried using @JsonSetter but to no avail. Probably Jackson just looks at the base class and sees ID is not accessible so it skips setting it... @MappedSuperclass public abstract class AbstractPersistable<PK extends Serializable> implements Persistable<PK> { @Id @GeneratedValue(strategy = GenerationType.AUTO) private PK id; public PK getId() { return id; } protected void setId(final PK id) { this.id = id; } Subclasses: public class A extends AbstractPersistable<Long> { private String name; } public class B extends AbstractPersistable<Long> { private A a; private int value; // getter, setter // make base class setter accessible @Override @JsonSetter("id") public void setId(Long id) { super.setId(id); } } Now if there are some As in our database and we want to create a new B via the REST resource: @POST @Consumes(MediaType.APPLICATION_JSON) @Produces(MediaType.APPLICATION_JSON) @Transactional public Response create(B b) { if (b.getA().getId() == null) cry(); } with a JSON String like this {"a":{"id":"1","name":"foo"},"value":"123"}. The incoming B will have the A reference but without an ID. Is there any way to tell Jackson to either ignore the base class setter or tell it to use the subclass setter instead? I've just found out about @JsonTypeInfo but I'm not sure this is what I need or how to use it. Thanks for any help!
