• 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

  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).

• Updating a Single Column In Room Database

  That's the function I'm using for updat

  private fun updateSettingsDatabase(settingsDao: SettingsDao) {
          lifecycleScope.launch {
              settingsDao.update(SettingsEntity(
                  1,
                  nightMode=nightModeResult,
              ))
          }
  }
  
  @Query("SELECT * FROM `settings-table`")
  fun fetchCurrentSettings(): Flow<List<SettingsEntity>>
  

  I specified nightMode= because I thought that this way I'm only updating this colummn, but it turns out that it resets every column, how do I update a single column, while keeping the values the rest of the columns?

• Android ZoneDateTime.withHour always sets hour to 8

  So I am tring to schedule alarm at a particular time on current day using AlarmManager. To do that I am using ZoneDateTime to get current time and then updating it to the hour at which I need to set the alarm. But for some reason time.withHour is giving me 8pm or 8am no matter what hour I am passing to it. Am I doing something wrong here?

  var time = ZonedDateTime.now()    //getting current time at my timezone
  time = time.withHour(22).withMinute(8).withSecond(0)
  print(time)                       //getting 8am/8pm at my timezone
  val timeMilis = time.toInstant().toEpochMilli()
