• Read each name in Array list to create seperate object for

  I have a file that has student names, age, and an id number. I have a student class that holds the everything above for each student object. I stored all the names, id numbers. and age separately in an array list. Now im trying to assign the info to create a student object.

  public class Student {
      private String lName;
      private int idNumber;
      private int age;
  
      public Student() {
          lName = "";
          idNumber = 0;
          age = 0;
      }
      public Student(String l, int i, int a) {
          lName = l;
          idNumber = i;
          age = a;
      }
  
      public void setName(String last) {
          lName = last;
      }
  
      public String getName() {
          return lName;
      }
  
      public void setIdNum(int num) {
          idNumber = num;
      }
  
      public int getIdNum() {
          return idNumber;
      }
  
      public void setAge(int a) {
          age = a;
      }
  
      public int getAge() {
          return age;
      }
  }
  

  My Text File looks something like this: This info is stored in parallel array lists. I don't quite get how to implement this into an object to pass it into my second contractor method.

    Andrew        7742         20
  

  Here's what I've tried;

  public static void main(String[] args) {
      String file = "studentData.txt";
      Scanner reader = new Scanner(file);
  
      ArrayList<String> lastNames = lNames(file);
      ArrayList<Integer> idNumbers = idNum(file);
      ArrayList<Integer> ageList = ages(file);
  
      Scanner input = new Scanner(System.in);
  
      Student s1 = new Student();
  
      // confused about how to implement this constructor with the textile info
      for (int i = 0; i<idNumbers.size(); i++) {
          Student user = new Student(lastNames.get(i), idNumbers.get(i), ageList.get(i));
      }
  
      //user enters idNumber to display age
      System.out.println("Enter ID Number"); //exception handling to be added
      int idNum = input.nextInt();
  
      for (int i = 0; i<idNumbers.size(); i++) {
          if (idNum == idNumbers.get(i)) {
              s1.setAge(ageList.get(i));
              System.out.println(s1.getAge());
  
          }
      }

• Using EdittextPreference for Goto search

  sorry for my poor English. I want to use EditTextPreference in my bottom nav like the pic below, ![screenshot][1]

  I have recycleview xml in my project with in many sub cardview layouts(which is scrollable) and I want to create item in the bottom nav which is called "Goto". When the "Goto" item is clicked i want it to pop-up like the screenshot. And when user enters a number(according to the cardviews i.e if the number of cardview is 40 user must enter 1-40) I want to search the cardview by its ID. Thank you and I hope u got it, If u have any questions let me know [1]: https://i.stack.imgur.com/grK8P.jpg

  My xml format look like this. As you see in the blow since the cardviews are huge in number it is not cool to scroll all the way down that is why i need Goto item in the bottom nav to search it by its ID when the user click number in the EditTextPreference as u see in the screenshot. i.e The screenshot is not from my app

• How to get remaining time of the day in java?

  I would like to calculate the time remaining for next day 00:00:00 from the current date time.

  For e.g. time difference between 2022-05-07T05:49:41.883807900Z and 2022-05-08T00:00:00Z

  Expected answer: 18:10:19 or 65419 (in seconds).

  How can I achieve this with efficiently using java 8?

• How to run Garabge Collection of BlobStore in Jackrabbit Oak?

  Using Oak version 1.42 (with java 17), I created a segment NodeStore, backed by a FileBlobStore, like this:

  FileBlobStore fileBlobStore = new FileBlobStore("…");
  SegmentGCOptions gcOptions = SegmentGCOptions.defaultGCOptions().setEstimationDisabled(true);
  FileStore fileStore = FileStoreBuilder.
          fileStoreBuilder(new File("…")).
          withBlobStore(blobStore).
          withGCOptions(gcOptions).
          build();
  Repository repository = new Jcr(new Oak(nodeStore)).createRepository()
  

  Then, I create a blob and later I delete it.

  The file associated to the blob is still on the file system, and, in my understanding, a garbage collection is needed in order to actually have it removed.

  What's the proper way to run the Garbage Collector?

  By reading the documentation - and taking into account that the whole thing is NOT run within an Osgi container - it seems that you should call MarkSweepGarbageCollector#collectGarbage(false), but it's not clear to me what are supposed to be the arguments of the constructor (or whether I can get a reference to an instance from some other data structure) - for instance:

  MarkSweepGarbageCollector garbageCollector = new MarkSweepGarbageCollector(
                      new SegmentBlobReferenceRetriever(fileStore),
                      blobStore,
                      executor,
                      "some path…",
                      10, // do not have any idea of what this parameter is and what is supposed to be set 
                      1, // are these millis? Or millis from epoch? No idea…
                      null) // no idea what it is this - but it's allowed to be null
  

  This way the blob is NOT deleted - with very little surprise, given that it's unclear to me what the parameters exactly are, and the exact purpose/meaning of some phases (e.g. the blobs are "marked", but I wasn't able to find out what this "mark" means - even by looking at the code…).

  I have also tried to call fileStore.fullGC(); before collectGarbage (thinking that maybe the blob wasn't deleted because of some "stale" data), but with no luck.

  Maybe the blob is not deleted because it's referenced in the versions history?

  If so, what's the proper way to get rid of the blob - firstly delete the version history (how?) and then run the garabage collection?

  ---

  I did some more investigations, and I also created a mini-program that replicate the issue:

  • you can find the program here on github
  • by following the program flow step-by-step, imo the issue is that, in the "mark" phase (that is when the GC looks for blobs that are actually still "in use"), the deleted blob reference is still there, i.e. it is still present in the BinaryReferencesIndex; therefore, it is marked, and consequently, begin both marked and available, it is not even considered a "candidate" for sweeping.

  I think that maybe this could have something to do with the way I add the blob: code follows, please refer to the above github for full context:

  Node rootFolder = session.getRootNode();
  Node fileNode = rootFolder.addNode(temporaryFile.getName(), "nt:file");
  fileNode.addMixin("mix:referenceable");
  Node fileContentNode = fileNode.addNode("jcr:content", "nt:resource");
  fileContentNode.setProperty("jcr:data", "");
  session.save();
  
  Blob blob = nodeStore.createBlob(FileUtils.openInputStream(temporaryFile));
  NodeBuilder rootBuilder = nodeStore.getRoot().builder();
  NodeBuilder fileContentNodeBuilder = getNodeBuilder(fileContentNode, rootBuilder);
  fileContentNodeBuilder.setProperty("jcr:data", blob);
  nodeStore.merge(rootBuilder, EmptyHook.INSTANCE, CommitInfo.EMPTY);
  session.save();

• AEM slingmodels - why do we need unused adaptables in each model? Why need both Resource & SlingHTTPRequest?

  I am working on a project where every model has this line:

  @Model(adaptables = { SlingHttpServletRequest.class,Resource.class },
   defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
  

  In my understanding:

  1. If Resource or SlingHTTPRequest is not to be used, this dependency injection must be removed from the model
  2. SlingHTTPRequest can help obtain resource with the use of .getResource method anyway, so using SlingHTTPServeltRequest class alone, with required dependencyInjectionStrategy should be sufficient, and Resource class as an adaptable is never needed?

  Please share your thoughts. Thanks in advance!
