instance of a class using the newInstance method in

| NoClassDefFoundError | Thrown if the Java Virtual Machine or a
ClassLoader instance tries to load in the definition
of a class (as part of a normal method call or as part of creating

definition of the class could be found. |
| NoSuchFieldError | Thrown if an application tries to access or modify a specified field of an object, and that object no longer has that field. |

| Collection<E> | The root interface in the collection hierarchy. |
| Comparator<T> | A comparison function, which imposes a total ordering on some collection of objects. |
| Enumeration<E> | An object that implements the Enumeration interface generates a series of elements, one at a time. |
| EventListener | A tagging interface that all event listener interfaces must extend. |

implemented by any class that needs to perform custom formatting
using the 's' conversion specifier of

. |
| Iterator<E> | An iterator over a collection. |
| List<E> | An ordered collection (also known as a sequence). |
| ListIterator<E> | An iterator for lists that allows the programmer to traverse the list in either direction, modify the list during iteration, and obtain the iterator's current position in the list. |

| Observer | A class can implement the Observer
interface when it wants to be informed of changes in observable
