indexoutofboundsexception

问题 So I was combing through some logs from our web server the other day (looking for something else), when something peculiar caught my eye. java.lang.IndexOutOfBoundsException: Index: 15, Size: 19 at java.util.ArrayList.rangeCheck(Unknown Source) at java.util.ArrayList.get(Unknown Source) This seemed impossible to me. I looked up the source code for ArrayList#rangeCheck and it blew my mind private void rangeCheck(int index) { if (index >= size) throw new IndexOutOfBoundsException(outOfBoundsMsg

问题 The exact error: Index was out of range. Must be non-negative and less than the size of the collection. I've index arrays and lists countless times. I've used for loops with arrays and lists countless times. The data is there, it works. Except when I try to create a task for my function. Mind you, I successfully did this with a foreach loop for a similar function; this new one requires two arguments though, so I can't use a foreach loop properly. At least I don't think I can. Here is the

问题 I am using a recycler view. Here is the adapter public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> { private List<Contact> myContacts; private Activity activity; public MyAdapter(List<Contact> contacts,Activity activity) { this.myContacts = contacts; this.activity = activity; } public class ViewHolder extends RecyclerView.ViewHolder { public TextView mTextView; public ImageView mColorView; public LinearLayout linearLayout; public ViewHolder(View v,MyAdapter adapter) {

问题 Based upon another Headfirst exercise I'm having trouble with populating my GUI with the data of vehicles. I use a Controller class to manage my vehicle Object class. For some reason I'm getting an index out of range exception. Gui Class public class ShowroomDriver{ public static Showroom Cars = new Showroom("Cars"); public static void main(String[] args) { Showroom Cars = new Showroom("Cars"); Vehicle vechicle1 = new Vehicle("Ford"); Cars.addVehicle(vechicle1); GuiInterface gui = new

问题 I created a method that reads data from a database and puts it in a String array. Android Studio doesn't give syntax errors but when i launch my app the log says: 03-19 16:31:20.938 2518-2518/com.mms.dailypill E/AndroidRuntime﹕ FATAL EXCEPTION: main Process: com.mms.dailypill, PID: 2518 java.lang.ArrayIndexOutOfBoundsException: length=0; index=0 at com.mms.dailypill.DBManager.getMedicines(DBManager.java:56) The method code is: public String[] getMedicines() { SQLiteDatabase db = dbManager

问题 I got a problem with an IndexOutOfBoundsException while I want to update a ListView in JavaFX. What I need to do I have a ListView with elements that correspond to a small simulation. With a click on one list-element the graphical simulation updates based on the click a element of the ListView . Afterwards the ListView needs a update and other elements will be shown. That means all old elements will be removed and only the new ones will be shown. My code looks like that: public void init() {

问题 BACKGROUND: I'm importing the Stanford CoreNLP library into my clojure project. I was using version 3.5.1 but recently jumped directly into version 3.6.0, bypassing 3.5.2. As part of this update, because I was getting coreference information using the dcoref annotator, I needed to make small modifications so that my program used the coref annotator instead. In the past (v3.5.1), when I created a pipeline with the following annotators "tokenize, ssplit, pos, lemma, ner, parse, depparse, dcoref

问题 This question already has answers here : How to avoid ArrayIndexOutOfBoundsException or IndexOutOfBoundsException? [duplicate] (2 answers) Closed 3 years ago . I am running Java 8u102. I have a modal window that contains a Combobox whose items are a FilteredList created from a list of Strings. The ComboBox is editable so that the user can enter text (automatically converted to uppercase). The items in the ComboBox popup are then filtered such that only those items that start with the entered
