IndexOutOfBound Exception throwing Android

Closed 7 years ago.
I have an error coming up and it's saying it is in this method pointing at the address list. Does anyone has a suggestion why this is happening and the app crashes?
Appreciate it.

try {

} catch (IOException e) {

}
if (addressList != null){
Address addresses = addressList.get(0);
// my address lng and lgnt

If there are no elements in a list or array, you can not retrieve the first (non-existing) element.
The valid indices are:
0 -> (number of elements - 1)
If there are no elements, there is no valid index.

Please check my code.
I am trying to store information from excel to a object and based on search criteria, I am trying to get the values in console.

String filePath = "E:\\Java_All\\Assignment\\PreAuthOrig2.csv";

What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it?

When size of data is 600, there is no exceltion.
When the size of the data is 800 I am getting following exception, after completing all the iterations and exiting the loop at following line:
'imageAdapter = new ImageAdapter(MainActivity.getAppContext(), posters);'
Issue is not related to splitArray[] which is inside the loop. Please note that it works for smaller size data.
Please help.

One of the line included between the 600th and 800th line is incomplete.
Add this following line :
assert splitArray.length > 4 : "Following line lacks a column: " + data[i];
after :
splitArray = data[i].split("[*]");
It should tell you which line lacks the fifth column

I have build an application the code is right. Still I am getting an error of
java.lang.IndexOutOfBoundsException: Invalid index 7, size is 7
whenever I am running app. Can't figure out what is the problem

The index starts at 0 not at 1, you should get wrong value anyway.
its a good idea toi write unitTest for things like that, in order to find your error early.
Java array indexes start with 0 up to size-1 (inclusive).
You should fix your indexes accordingly:
subject = arrayOfListsA.get(1);
should be
subject = arrayOfListsA.get(0);
etc.
replace this
GridView gridView=(GridView) findViewById(R.id.gridLect1);
subject = arrayOfListsA.get(1);
subjecttype = arrayOfListsA.get(2);
day1= arrayOfListsA.get(3);
period= arrayOfListsA.get(4);
date1= arrayOfListsA.get(5);
section= arrayOfListsA.get(6);
batch= arrayOfListsA.get(7);
With
GridView gridView=(GridView) findViewById(R.id.gridLect1);
subject = arrayOfListsA.get(0);
subjecttype = arrayOfListsA.get(1);
day1= arrayOfListsA.get(2);
period= arrayOfListsA.get(3);
date1= arrayOfListsA.get(4);
section= arrayOfListsA.get(5);
batch= arrayOfListsA.get(6);
As index start with 0 not 1

What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it?
(26 answers)
Closed 7 years ago.
I am getting a string which I'm trying to convert to JSONArray. The length of the JSONArray is getting OK (if its 100 or 5000). but I am getting "java.lang.IndexOutOfBoundsException: Invalid index 50, size is 50". Below is my code.
try
{
JSONArray jsonArray = new JSONArray(returndResultForSNID);
System.out.println("jsonArray: "+jsonArray.length());
for(int i = 0; i < jsonArray.length(); i++)
{
snid = jsonArray.getJSONObject(i).getString("snid");
//number = jsonArray.getJSONObject(i).getString("phone");
phoneContactsDTOArrayList.add(new PhoneContactsDTO( contactNameArr.get(i).toString() , contactPhoneNumberArr.get(i).toString(), snid, "") );
//System.out.println( "Could jsonArray parse malformed JSON: " + snid +" _> "+number);
}
}
catch (Exception e)
{
System.out.println( "JSONArray error: " + e.toString() );
}
Arrays are 0 based.
It means that an array of size 50 has index from 0 to 49.
contactNameArr and contactPhoneNumberArr are probably smaller than the size of jsonArray. In particular jsonArray has a size bigger than 51 and one of the others has a dimension of 50.
My Java Application produces Null Pointer Exception from JCalander Combobox. I tried to catch the error. But that didnt work. Can someone assist me to fix this. Please.

calRecvDate.requestFocus();
}else if(txtShipSs.getText().isEmpty()){
////////////////////////////////////////////////////////////////
if (inputValidate() == true) {
try {
String shipId = txtShipId.getText();
String invID = txtInvoice.getText();
String shipSs = txtShipSs.getText();
String address = txtNtfAddress.getText();
String sipper = txtAShipper.getText();
String vessal = txtVessal.getText();
Date rcvDate = calRecvDate.getDate(); // Jcalander
String consignee = txtConsigne.getText();
ArrayList<ShippmentItems> shipItems = new ArrayList<ShippmentItems>();
tbmodel = (DefaultTableModel) tblItmQty.getModel();
for (int i = 0; i < tbmodel.getRowCount(); i++) {
String itmcode = (String) tbmodel.getValueAt(i, 0);
String itmName = (String) tbmodel.getValueAt(i, 1);
int qty = (int) tbmodel.getValueAt(i, 2);
ShippmentItems shpItems = new ShippmentItems(shipId, itmcode, itmName, qty);
shipItems.add(shpItems);
}
Since this throws the NPE:
calRecvDate.getDate()==null
The calRecvDate variable is null, and you will either need to check if it's null before using it, or make sure that it isn't null by tracing back in your code to where you think you've initialized it and fix the problem (since it isn't initialized).
To check if it's null, you could do:
if (calRecvDate != null) {
// use the calRecvDate variable here
} else {
// initialize the calRecvDate variable here
// or perhaps better, display a JOptionPane error message to the user
// that the date hasn't been selected, and exit this method by calling return:
return;
}
Again, don't use try/catch blocks to handle NullPointerExceptions.
