This Tutorial Provides a Detailed Explanation About an Important Exception thrown by Java Arrays i.e. ArrayIndexOutOfBoundsException with Simple Examples: We have learned all about Arrays in our previous tutorials. Arrays are static in nature and its dimension or size is determined at the time of their declaration. We also know that this size or the number of elements declared for the array are fixed and are numbered from 0. Sometimes, the program logic is such that the program tries to access the element from a non-existing index. For example, due to glitches in a program, a program might try to access the 11 th element in the array of 10 elements. This results in an abnormal condition. => What You Will Learn: • • • • • • • • • ArrayIndexOutOfBoundsException As already stated, when you try to access array elements beyond a specified length or a negative index, the compiler throws the ‘ArrayIndexOutOfBoundsException’. ArrayIndexOutOfBoundsException implements a ‘serializable’ interface and derives from the ‘indexOutOfBoundsException’ which in turn is derived from the RuntimeException class which is a subclass of the ‘exception’ class. All these classes belong to the ‘java.lang’ package. ArrayIndexOutOfBoundsException is a runtime, unchecked exception and thus need not be explicitly called from a method. Following is the class diagram of ArrayIndexOutOfBoundsException that shows the inheritance hierarchy as well as the constructors for this exception. Class Diagram Of Array...

To help programmers both anticipate and recover from RuntimeException. Given their potential to stop an otherwise properly functioning program dead in its tracks, developers should grasp Java's most common RuntimeExceptions. List of RuntimeException examples The 10 most common examples of RuntimeExceptions in Java are: • ArithmeticException • NullPointerException • ClassCastException • DateTimeException • ArrayIndexOutOfBoundsException • NegativeArraySizeException • ArrayStoreException • UnsupportedOperationException • NoSuchElementException • ConcurrentModificationException Anticipate the ArtithmeticException Data manipulation is a primary function of most Java applications. When data manipulation includes division, developers must be wary of division by zero. If zero ever becomes the denominator in a calculation, Java throws an ArithmeticException. int x = 100; int y = 0; // denominator is set to zero System. out.println( x/y ); // throws ArithmeticException In this example, the denominator is explicitly assigned to zero, so it's obvious that a divide-by-zero error will occur. If user input sets the denominator, the problem is less predictable. That's why data cleansing is an important function of every application. Negate the NullPointerException The NullPointerException is a very common RuntimeException that Java applications encounter. Any time a developer writes code that invokes a method on an uninitialized object in Java, a NullPointerException occurs. String data ...

Java knows it is a StackOverflow because... when it is a StackOverflow, the stack overflows. This doesn't happen when an array is indexed out of bounds. When an array is indexed out of bounds, there was code that tries to index into an array, and the index is out of bounds (not valid). Note that indexing an array is not trying to put more into it. When the stack overflows, there was code that tries to put more data on the stack. Note that putting data on the stack is not the same as trying to index into it - it's a stack, after all, not an array. These two are actually very different things. As the other guys have already mentioned, ArrayIndexOutOfBoundsException is an Exception that occurs when you are trying to access an array using an incorrect index. This could be caused by a very simple bug in programming logic. StackOverflowError is something more low-level. It has nothing to do with arrays and, contrary to what the other guys said, has nothing to do with the heap either. Try doing that trick with a List and you'll get an OutOfMemoryError instead. Now it's an Error that is much more similar to StackOverflowError than ArrayIndexOutOfBoundsException. Both OutOfMemoryError and StackOverflowError indicate that you're running out of memory, only in different segments. Running out of stack memory almost always occurs due to infinite recursion (unless you have a ridiculously long chain of methods calling each other with lots of local variables in them), and running out of h...

The purpose of this tutorial is to guide you through the process of resolving the ‘java.lang.ArrayIndexOutOfBoundsException’ error in Java. This error is a common occurrence when dealing with By understanding the error, identifying its causes, and learning effective troubleshooting techniques, you will be equipped with the knowledge to resolve this error and prevent it from occurring in your Java programs. In the upcoming sections, we will delve deeper into the ‘java.lang.ArrayIndexOutOfBoundsException’ error, explore its causes, and provide practical techniques to effectively resolve it. By the end of this tutorial, you will be equipped with the necessary knowledge and skills to tackle this error confidently. Let’s get started! Table of Contents • • • • • • • • • • • • Understanding the Error Definition of the ‘java.lang.ArrayIndexOutOfBoundsException’ Error The ‘java.lang.ArrayIndexOutOfBoundsException’ is a runtime exception in Java that occurs when you try to access an array element using an invalid index. In Java, arrays are zero-indexed, which means the first element is at index 0, the second at index 1, and so on. When an invalid index is used to access an array element, this exception is thrown, indicating that the index is outside the valid range of the array. Potential Consequences of Leaving the Error Unresolved Failing to address the ‘java.lang.ArrayIndexOutOfBoundsException’ error can have various consequences, including: • Program Crashes and Unpredictable Be...

Table of Contents • • • • • • • Here are few handy tips to avoid ArrayIndexOutOfBoundsException in Java: • Always remember that the array is a zero-based index, the first element is at the 0th index and the last element is at length – 1 index. • Pay special attention to the start and end conditions of the loop. • Beware of one-off errors like above. What does this mean java Lang ArrayIndexOutOfBoundsException? java.lang.ArrayIndexOutOfBoundsException. Thrown to indicate that an array has been accessed with an illegal index. The index is either negative or greater than or equal to the size of the array. What does index 0 out of bounds for length 0 mean in java? “index 0 out of bounds for length 0 java” Code Answer 1 means index 1 is invalid and it’s out of bound i.e. more than the length of the array. 2. Since array has a zero-based index in java , this means you are trying to access the second element of. 3. array which only contains one element. How do I stop ArrayIndexOutOfBoundsException? To avoid the ArrayIndexOutOfBoundsException use an index within specified index range. And always check whether your index is >= array. length . How do I fix Java Lang NumberFormatException? The NumberFormatException is an exception in Java, and therefore can be handled using try-catch blocks using the following steps: • Surround the statements that can throw an NumberFormatException in try-catch blocks. • Catch the NumberFormatException. • Depending on the requirements of the applicat...
