In this, we can initialize the 3 elements that means it can save index 0 to 2 into the array but within try block we are accessing the element in index 3. The expression which java agrees upon is index < size So the solution for such exception is to make the statement in the loop as i<list.size() This tutorial serves the solution for the java.lang.indexoutofboundsexception error, also educates about the reason causing this with the help of code examples. The indexoutofboundsexception is a runtime exception that is thrown when you try to access an index that is either less than zero or greater than the size of the array (or any other collection). Constructs a new indexoutofboundsexception class with an argument indicating the illegal index.
This exception is thrown to indicate that an index of some sort (such as to an array, a string, or a list) is out of range Understanding how this exception works, why it occurs, and how to handle it properly is crucial for writing robust java code. The java.lang.indexoutofboundsexception 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.
