The Clone() method returns a new array (a shallow copy) object containing all the elements in the original array.  The CopyTo() method copies the elements into another existing array.  Both perform a shallow copy.  A shallow copy means the contents (each array element) contains references to the same object as the elements in the original array.  A deep copy (which neither of these methods performs) would create a new instance of each element's object, resulting in a different, yet identacle object.

An object that contains a servlet's view of the Web application within which the servlet is running. Using the context, a servlet can log events, obtain URL references to resources, and set and store attributes that other servlets in the context can use. J2EE

They check to see if the references both point to the same object.

Subqueries, or nested queries, are used to bring back a set of rows to be used by the parent query. Depending on how the subquery is written, it can be executed once for the parent query or it can be executed once for each row returned by the parent query. If the subquery is executed for each row of the parent, this is called a correlated subquery.

A correlated subquery can be easily identified if it contains any references to the parent subquery columns in its WHERE clause. Columns from the subquery cannot be referenced anywhere else in the parent query. The following example demonstrates a non-correlated subquery.

A tag that references a JSP custom action.

Hypertext Markup Language. A markup language for hypertext documents on the Internet. HTML enables the embedding of images,

sounds, video streams, form fields, references to other objects with URLs, and basic text formatting.

That part of a DTD that is defined by references to external DTD files.

An enterprise bean that represents persistent data maintained in a database. An entity bean can manage its own persistence or

can delegate this function to its container. An entity bean is identified by a primary key. If the container in which an

entity bean is hosted crashes, the entity bean, its primary key, and any remote references survive the crash.

A distinct, individual item that can be included in an XML document by referencing it. Such an entity reference can name an

entity as small as a character (for example, <, which references the less-than symbol or left angle bracket, <). An entity

reference can also reference an entire document, an external entity, or a collection of DTD definitions.
