• 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.

    Josh          2134         19
    Smith         5256         21
    Rogers        9248         19
    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

• suggestions on fulltext search or already existing search algorithms

  Can someone suggest how to solve the below seach problem easily, I mean is there any algorithm, or full text search will be suffice for this?

  There is below classification of items data,

  ItemCategory        ItemCluster     ItemSubCluster      SubCluster  Items
  Vegetable       Root vegetables     Root            WithOutSkin potato, sweet potato, yam

  The inputs will be some thing like,

  sweet potato, yam Yam, Potato garlik, onion lettuce, spinach, silverbeet lettuce, silverbeet lettuce, silverbeet, spinach

  From the input, I want to get the mapping of the input items those belongs to which ItemCategory, ItemCluster, ItemSubCluster, SubCluster.

  Any help will be much appreciated.

• Writing multithreaded code to generate incremental index

  I want to write a code in following scenario : we want to design an invoice generator.this invoice generator also generates an incremental invoice no .Also note that for some reasons we dont use something like sql Auto Increment here and we want to use C# (I wrote the increment logic). since several users can send requests at a time it means that we dont have to give the same invoice no to them (I used lock for it and I wrote it).

  Now i have written increment logic. and i take care of multiple users requests with lock . and I wrote CRUD for mongodb database.

  My problem is that my increent logic is naive. each time i find maximum and i increment by one which is not scalable. and another problem is that when we delete a record we don't want the invoice no to be repeated and since we find max if the deleted record had the max value then the invoice no would be duplicate and this is something we don't want to have.

  I really don't know how to handle the problem. specially in case of deletion should i store max values in a file or should i change increment logic completely?

  i appreciate any help
• How can I speed up the routing process in OSMNX?

  Say I have two taxi orders with Origin1、Destination1 and Origin2、Destination2(O1,O2,D1,D2). I want to calculate the possibility of ridesharing, so I need the path between two different points. And, here's my code:

  def path_time(point1, point2):
      path = ox.distance.shortest_path(road, point1, point2, weight='travel_time')
      if path is None:
          #If there isn't a path, a big weight will be set, and it won't be selected during the matching process.
          route_time = 9999
      else:
          route_time = int(sum(ox.utils_graph.get_route_edge_attributes(road, path, "travel_time")))
      return route_time,path
  

  Since there is four points, I need to do this six times, where tp means travel path :

  tpO1O2 = path_time(O1,O2)
  tpO1D1 = path_time(O1,D1)
  tpO1D2 = path_time(O1,D2)
  tpO2D1 = path_time(O2,D1)
  tpO2D2 = path_time(O2,D2)
  tpD1D2 = path_time(D1,D2)
  

  It's okay if I only have two points, but I got a 2 million order set, and each order has hundreds of potential matched orders. So this will take me a lot of time.

  Does anyone knows how can I speed up this process? Thank you!

• Lighthouse CLI: how to use current browser settings(running with extensions installed)

  Try lighthouse CLI to measure performance of URLs with some extensions on.

  With lighthouse https://www.bing.com/search?q=curse+words --output json --output-path D:\lighthouseResults\0506.json --disable-device-emulation --chrome-flags="--user-agent=edge --window-size=360,640 --enable-experimental-extension-apis", it doesn't seem that the extension was working(usually takes a few seconds, very slow), and did not find http requests that were suppose to be there in the report.

  How should I do it in Lighthouse or I'm looking at the wrong tool?
