Point An enum specifies a list of constant values assigned to a type. Point An enum can be declared outside or inside a class, but NOT in a method. Point An enum declared outside a class must NOT be marked static, final, abstract, protected, or private. Point Enums can contain constructors, methods, variables, and constant class usmanfazal.com: App Shah. @slim As the stream is ordered, findFirst() exhibits the same behavior as the original pre-java 8 code in case of multiple matches. Although I suspect a bijective mapping between enum's values and names, I don't expect much difference in terms of performance between findFirst() and findAny() (and as you said, it's questionable). That said, I would use the second approach. Interface EnumerationE>. All Known Subinterfaces: NamingEnumeration All Known Implementing Classes: StringTokenizer. public interface Enumeration An object that implements the Enumeration interface generates a series of elements, one at a time. Successive calls to the nextElement method return successive elements of the series.

Java 8 ChronoUnits Enum - Learn Java 8 in simple and easy steps starting from basic to advanced concepts with examples including Overview, Environment Setup, Lambda expressions, Default methods, Streams, Optional, Nashorn JavaScript Engine,New Date Time API, Base stream(spliteratorUnknownSize(toIterator(enumeration), IMMUTABLE), false) now you have a standard Java 8 Stream to be used in any way! You may pass true for parallel processing. To convert from Enumeration to Iterator use any of: usmanfazal.comator() from Spring or you can use; usmanfazal.comator() from Apache Commons Collections More information about enums, including descriptions of the implicitly declared methods synthesized by the compiler, can be found in section of The Java™ Language Specification. Note that when using an enumeration type as the type of a set or as the type of the keys in a map, specialized and efficient set and map implementations are available. Interface EnumerationE>.
