  • Extracting a given number of the highest values in a List

    - by James P.
    I'm seeking to display a fixed number of items on a web page according to their respective weight (represented by an Integer). The List where these items are found can be of virtually any size. The first solution that comes to mind is to do a Collections.sort() and to get the items one by one by going through the List. Is there a more elegant solution though that could be used to prepare, say, the top eight items?

  • listView.setAdapter doesn't work

    - by Bowiz2
    I have a listview called quotesList, and I am trying to use an adapter to put information in it. Here is my code: ListView listView = (ListView) findViewById(R.id.quotesList); String[]values={"Android","iOS","Windows Phone","Other Stuff"}; ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, android.R.id.text1,values); listView.setAdapter(adapter); The only error that Eclipse shows is in the listView.setAdapter(adapter) line. The bold represents where the red squiggly is. Syntax error on token "adapter", VariableDeclaratorId expected after this token The period after listView gives an error as well, but I'm pretty sure its just related to the other error, as its a syntax error. Syntax error on token(s), misplaced construct(s) Thanks in advance!

  • Generate encoding String according to creation order.

    - by Tony
    I need to generate encoding String for each item I inserted into the database. for example: x00001 for the first item x00002 for the sencond item x00003 for the third item The way I chose to do this is counting the rows. Before I insert the third item, I count against the database, I know there're already 2 rows, so the next encoding is ended with 3. But there is a problem. If I delete the second item, the forth item will not be the x00004,but x00003. I can add additional columns to table, to store the next encoding, I don't know if there's other better solutions ?

  • OnClickListener onClick=true and selector

    - by azerto00
    I have not found any answer for my problem, so I need your help ... I have an LinearLayout which I want to be clickable in order to lunch another activity. So I implement an onClickListener to it. I created an selector for this LinearLayout in order that what someone click on it, the background change. I just don't understand that : If my LinearLayout doesn't have android:clickable="true" in the xml, I'm able to click on it and get what I want but the selector doesn't work. If I remove this line, it is the opposite .. the selector work but not the onClick event. So, can anyone can explain me why ? Just in case, here is my the content of my selector file : <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:drawable="@drawable/btn_restaurants_background_state_pressed" android:state_pressed="true"></item> <item android:drawable="@drawable/btn_restaurants_background_state_pressed" android:state_focused="true"></item> <item android:drawable="@drawable/btn_restaurants_background_state_pressed" android:state_selected="true"></item> <item android:drawable="@drawable/btn_restaurants_background_state_normal"></item> </selector> Thanks you in advance

  • regex: trim all strings directly preceeded by digit except if string belongs to predefined set of st

    - by Geert-Jan
    I've got addresses I need to clean up for matching purposes. Part of the process is trimming unwanted suffices from housenumbers, e.g: mainstreet 4a --> mainstreet 4. However I don't want: 618 5th Ave SW --> 618 5 Ave SW in other words there are some strings (for now: st, nd, rd, th) which I don't want to strip. What would be the best method of doing this (regex or otherwise) ? a wokring regex without the exceptions would be: a = a.replaceAll("(^| )([0-9]+)[a-z]+($| )","$1$2$3"); //replace 1a --> 1 I thought about first searching and substiting the special cases with special characters while keeping the references in a map, then do the above regex, and then doing the reverse substitute using the reference map, but I'm looking for a simpler solution. Thanks

  • Why is an anonymous inner class containing nothing generated from this code?

    - by Andrew Westberg
    When run through javac on the cmd line Sun JVM 1.6.0_20, this code produces 6 .class files OuterClass.class OuterClass$1.class OuterClass$InnerClass.class OuterClass$InnerClass2.class OuterClass$InnerClass$InnerInnerClass.class OuterClass$PrivateInnerClass.class When run through JDT in eclipse, it produces only 5 classes. OuterClass.class OuterClass$1.class OuterClass$InnerClass.class OuterClass$InnerClass2.class OuterClass$InnerClass$InnerInnerClass.class OuterClass$PrivateInnerClass.class When decompiled, OuterClass$1.class contains nothing. Where is this extra class coming from and why is it created? package com.test; public class OuterClass { public class InnerClass { public class InnerInnerClass { } } public class InnerClass2 { } //this class should not exist in OuterClass after dummifying private class PrivateInnerClass { private String getString() { return "hello PrivateInnerClass"; } } public String getStringFromPrivateInner() { return new PrivateInnerClass().getString(); } }

  • Is there a way to filter out offensive words from Jcaptcha?

    - by elduff
    We are using JCaptcha for a captcha tool in a small app that my team is writing. However, just during development time (on a small team - 4 of us), we've run across a number of curse words and other potentially offensive words for the actual captchas. Is there a way to filter out potentially offensive words so that they are not presented to the user?

  • How to signal object instantiation in a Collaboration/Communication Diagram?

    - by devoured elysium
    I'd like to know how to translate the following line of code to a Collaboration Diagram: Food food = new Food("abc", 123); I know that I can call an Food's method using the following notation: MyStaticMethod() ----------------------> -------- | | | Food | | | -------- being that equivalent to Taste taste = Food.MyStaticMethod(); and MyInstanceMethod() ----------------------> --------------- | | | food : Food | | | --------------- is equivalent to food.MyInstanceMethod(); but how do I signal that I want to call a given constructor on Food? Thanks

  • How hide some nodes in Richfaces Tree (do not render nodes by condition)?

    - by VestniK
    I have a tree of categories and courses in my SEAM application. Courses may be active and inactive. I want to be able to show only active or all courses in my tree. I've decided to always build complete tree in my PAGE scope component since building this tree is quite expensive operation. I have boolean flag courseActive in the data wrapped by TreeNode<T>. Now I can't find the way to show courses node only if this flag is true. The best result I've achieved with the following code: <h:outputLabel for="showInactiveCheckbox" value="show all courses: "/> <h:selectBooleanCheckbox id="showInactiveCheckbox" value="#{categoryTreeEditorModel.showAllCoursesInTree}"> <a4j:support event="onchange" reRender="categoryTree"/> </h:selectBooleanCheckbox> <rich:tree id="categoryTree" value="#{categoryTree}" var="item" switchType="ajax" ajaxSubmitSelection="true" reRender="categoryTree,controls" adviseNodeOpened="#{categoryTreeActions.adviseRootOpened}" nodeSelectListener="#{categoryTreeActions.processSelection}" nodeFace="#{item.typeName}"> <rich:treeNode type="Category" icon="..." iconLeaf="..."> <h:outputText value="#{item.title}"/> </rich:treeNode> <rich:treeNode type="Course" icon="..." iconLeaf="..." rendered="#{item.courseActive or categoryTreeEditorModel.showAllCoursesInTree}"> <h:outputText rendered="#{item.courseActive}" value="#{item.title}"/> <h:outputText rendered="#{not item.courseActive}" value="#{item.title}" style="color:#{a4jSkin.inactiveTextColor}"/> </rich:treeNode> </rich:tree> the only problem is if some node is not listed in any rich:treeNode it just still shown with title obtained by Object.toString() method insted of being hidden. Does anybody know how to not show some nodes in the Richfases tree according to some condition?

  • Setting custom HTTP request headers in an URL object doesn't work.

    - by Blagovest Buyukliev
    I am trying to fetch an image from an IP camera using HTTP. The camera requires HTTP basic authentication, so I have to add the corresponding request header: URL url = new URL("http://myipcam/snapshot.jpg"); URLConnection uc = url.openConnection(); uc.setRequestProperty("Authorization", "Basic " + new String(Base64.encode("user:pass".getBytes()))); // outputs "null" System.out.println(uc.getRequestProperty("Authorization")); I am later passing the url object to ImageIO.read(), and, as you can guess, I am getting an HTTP 401 Unauthorized, although user and pass are correct. What am I doing wrong? I've also tried new URL("http://user:pass@myipcam/snapshot.jpg"), but that doesn't work either.

  • How to prevent mvn jetty:run from executing test phase?

    - by tputkonen
    We use MySQL in production, and Derby for unit tests. Our pom.xml copies Derby version of persistence.xml before tests, and replaces it with the MySQL version in prepare-package phase: <plugin> <artifactId>maven-antrun-plugin</artifactId> <version>1.3</version> <executions> <execution> <id>copy-test-persistence</id> <phase>process-test-resources</phase> <configuration> <tasks> <!--replace the "proper" persistence.xml with the "test" version--> <copy file="${project.build.testOutputDirectory}/META-INF/persistence.xml.test" tofile="${project.build.outputDirectory}/META-INF/persistence.xml" overwrite="true" verbose="true" failonerror="true" /> </tasks> </configuration> <goals> <goal>run</goal> </goals> </execution> <execution> <id>restore-persistence</id> <phase>prepare-package</phase> <configuration> <tasks> <!--restore the "proper" persistence.xml--> <copy file="${project.build.outputDirectory}/META-INF/persistence.xml.production" tofile="${project.build.outputDirectory}/META-INF/persistence.xml" overwrite="true" verbose="true" failonerror="true" /> </tasks> </configuration> <goals> <goal>run</goal> </goals> </execution> </executions> </plugin> The problem is, that if I execute mvn jetty:run it will execute the test persistence.xml file copy task before starting jetty. I want it to be run using the deployment version. How can I fix this?

  • Setting the content-type of a response in Struts2

    - by Thomas
    So, I'm using freemarker templates with Struts2 to formulate my responses. However, since I'm trying to use taconite as well, I need the response to be sent with the content type of "text/xml". I can't seem to find a way to use freemarker directives to set the content type, and I am not well versed enough in struts to know if there is a way to do it through that. So, how should I go about this?

  • Do "if" statements affect in the time complexity analysis?

    - by FranXh
    According to my analysis, the running time of this algorithm should be N2, because each of the loops goes once through all the elements. I am not sure whether the presence of the if statement changes the time complexity? for(int i=0; i<N; i++){ for(int j=1; j<N; j++){ System.out.println("Yayyyy"); if(i<=j){ System.out.println("Yayyy not"); } } }

  • Removing quotation marks in JSONObject

    - by Spike Williams
    I'm using the net.sf.json.JSONObject to create some data to be sent to a front end application, and I don't like the ways ts adding quotation marks to every field name. For example: myString = new JSONObject().put("JSON", "Hello, World!").toString(); produces the string {"JSON": "Hello, World"}. What I want it to return is {JSON: "Hello, World"} - without quotes around "JSON". What do I have to do to make that happen?
