Class ConcurrentModificationException

Implemented Interfaces:
Serializable

public class ConcurrentModificationException
extends RuntimeException

Exception that is thrown by the collections classes when it is detected that a modification has been made to a data structure when this is not allowed, such as when a collection is structurally modified while an Iterator is operating over it. In cases where this can be detected, a ConcurrentModificationException will be thrown. An Iterator that detects this condition is referred to as fail-fast. Notice that this can occur even in single-threaded designs, if you call methods out of order.
