A Stream represents a sequence of elements and supports different kind of operations to perform computations upon those elements. With Java 8, Collection interface has two methods to generate a Stream: stream() and parallelStream(). Stream operations are either intermediate or terminal. Intermediate operations return a Stream so multiple intermediate operations can be chained before the Stream is closed. Terminal operations are either void or return a non-stream result.

Java enums (declared using the enum keyword) are shorthand syntax for sizable quantities of constants of a single class.
