How to avoid ArrayIndexOutOfBoundsException in Java?

The ArrayIndexOutOfBoundsException in Java occurs whenever someone try to access any item of an array at an index which is not present in the array. In other words, the index may be negative or exceed the size of an array.<br><br> The ArrayIndexOutOfBoundsException is a subclass of IndexOutOfBoundsException, and it implements the Serializable interface.<br><br> We can avoid this exception by using a type-safe Iterator. These are the iterators which allow modifications of a collection while iterating over it.<br><br> <pre>HashMap<Integer,Integer> map = new HashMap<>(); map.put(1,1); map.put(2,2); map.put(3,3); map.put(4,4); final Iterator<Integer> it = map.Keyset().iterator(); for (int i = 0; it.hasNext(); i++) { System.out.println(it.next()); } </pre>
