Getting error : Caused by: java.lang.ArrayIndexOutOfBoundsException: length=3; index=4

I got error in following code. I am trying to save my traveled distance in SQLite Database but getting error in SQLite Database. I don't know how to manage the array length. I am getting an error called
java.lang.ArrayIndexOutOfBoundsException: length=3; index=4.

Getting Error on this line :

Thanks in advance.

Most probably, the cursor only contains 3 resulting columns. Therefore you can only access 0, 1 and 2.

Shravan, you can't fetch 4th index value from the array when there are only 3 values.
You can access the index values of 0,1,2 only.
Use breakpoint on the crashing line and you will get a clear picture.

Well, you cant access 4th element of an array having just 3 elements. Mostly people confuse this having a little background in C/C++.
This is the difference in C/C++ and JAVA.
Suppose you have something like this:
int arr[] = {1,2,3};
Now, if you do arr[3] in C/C++, it will return some garbage value, whatever is present at the that particular address, but in JAVA , ArrayIndexOutOfBoundsException is thrown.

Separating a quiz questions into different groups

I've searched a lot for this question but can't seem to actually find an answer. My quiz app works well, but I realized that 50 questions all at once were too many.
Right now, my app works by people clicking a button that says "Begin" and they enter the quiz. After the quiz, all of the questions that they got wrong are shown with the correct answer. However, what I'd like to do is group these into questions of 10. So, select "Question Set 1" Button, "Question Set 2" Button, etc. Then, I'd still like to show the correct answer to the questions contained in this question set.
I'm not actually sure how to separate the questions and have my logic still work. Below I've included by database helper class. I've exempted most of the questions to shorten it. Thank you so much!

It seems to me that your Question objects and corresponding table should contain an additional field which indicates which Question Set they belong to. Your DbHelper class should then beable to query Questions by set. Or alternatively you could sort all Questions by their set in the java code, but I would prefer to leave that to the db.
However, If you wish to divide all the questions into sets of 10 you could try something like the following:
List<Set<Question>> questionSets = new ArrayList<Set<Question>>();
Set<Question> questionSet = new HashSet<Question>();
questionSets.add(questionSet);
int counter = 0;
for(Question question : dbHelper.getAllQuestions()){
if(++counter > 10){
counter = 0;
questionSet = new HashSet<Question>();
questionSets.add(questionSet);
}
questionSet.add(question);
}
This will collect ten questions into a Set and the add them to the list of Question Sets. You could then access each question set from that list.

Random data in SQLite

I am asking your help to fix my problem in my android applications. I have a project to make a quiz apps, and I want to implement linear congruential method in this game. I have success to random my data, but I still have no idea how to implement the method. Here is my code;
public class QuizHelper extends SQLiteOpenHelper {

you can find the formula here
https://id.wikipedia.org/wiki/Metode_linear_kongruen

SQlite Random return pseudo-random integer between -9223372036854775808 and +9223372036854775807.
https://sqlite.org/lang_corefunc.html#randomblob
If you use random() given by android that should solve your problem
Random class uses a 48-bit seed, which is modified using a linear congruential formula.
https://developer.android.com/reference/java/util/Random.html
Change this line
String selectQuery = "SELECT * FROM " + TABLE_QUEST + " ORDER BY RANDOM(), null";
to
Random r = new Random();
int i1 = r.nextInt(MAX_Database_row_Count - Min_Database_row_count) + Min_Database_row_count;
String selectQuery = "SELECT * FROM " + TABLE_QUEST + " ORDER BY "+Integer.toString(i1)+", null";

where clause is not working in sqlite database in android

I added a column named id in the database "quest" by using the OnUpgrade() method.But when i run the app there is no data in the arrayList. I used Log for checking the cursor and ArrayList size,Both are zero. When i ran the app first Time it gaves an error of not having a column named id after that it gaves an error of :

I checked the query many time.When i used Select * from +TABLE_QUEST; there are 5 entries in the list and it works fine but not in this case.please help.

Focus on the Exception:
no such table: questWHEREqidBETWEEN0AND10
You are missing space between table name , Where clause , And keyword etc . so the query makes it a whole string
use:
String selectQuery = "SELECT * FROM " + TABLE_QUEST + " WHERE " + KEY_ID + " BETWEEN " + catogaries.bc + " AND " +catogaries.ab;
