Thanks in Advance. Thanks and Regards, Abhi.
Hi Expert, I saw your post in SDN. That you have solved the issue by your self I saw. Can you please explain me how you have solved this issue. I am facing the same problem The
0 in Java is thrown when an index used in arrays, lists, or strings is not valid. A valid index must be a number from 0 up to one less than the total number of items. For example, in a list of 3 items, the valid indices are 0, 1, and 2. Here’s a quick example:
The error message you’d get would look something like this:
Here are some other common ways the IndexOutOfBoundsException might be thrown:
You may also see StringIndexOutOfBoundsException and ArrayIndexOutOfBoundsException, which are more specific subtypes of the IndexOutOfBoundsException, indicating out-of-bounds conditions for strings and arrays, respectively. How to Fix java.lang.IndexOutOfBoundsExceptionFixing an IndexOutOfBoundsException depends on the situation that led to it. Let’s look at some typical problem scenarios and how to fix each. Sublist OperationsScenario: You created a sublist with invalid indices.
Fix: Ensure that the indices for subList are within the valid range of the original list.
The reason
5 works correctly is that it specifies a valid segment of the list where the starting index is 2 (the third item, 3) and the ending index is 4 (just beyond the fourth item, 4). This operation does not go out of bounds since the original list has elements at indices 0, 1, 2, and 3. Thus, a request for indices 2 to 3 (inclusive of 2 and exclusive of 4) is valid. String Manipulation MethodsScenario: You’re accessing characters or substrings with invalid indices. For example:
Fix: Adjust the index to be within the valid range.
Vector or StackScenario: You’re accessing elements from a Vector or Stack with an invalid index.
Fix: Use methods that check if the stack is empty or ensure indices are within range.
Custom Data StructuresScenario: You’re accessing elements in a custom data structure without bounds checks.
Fix: Implement bounds checking before accessing elements.
