- public class ConcurrentModificationException
- extends java.lang.RuntimeException
This exception may be thrown by methods that have detected concurrent
modification of a backing object when such modification is not permissible.
For example, it is not permssible for one thread to modify a Collection
while another thread is iterating over it. In general, the results of the
iteration are undefined under these circumstances. Some Iterator
implementations (including those of all the collection implementations
provided by the JDK) may choose to throw this exception if this behavior is
detected. Iterators that do this are known as fail-fast
iterators, as they fail quickly and cleanly, rather that risking arbitrary,
non-deterministic behavior at an undetermined time in the future.
