In
2014, Oracle Corporation released Java 8 on 18 March, which was another
milestone release for the Java ecosystem. Java is already the most modern,
statically typed, object oriented language available for fast software development,
but in Java 8 new important enhancements are added to to the
language, such as lambda expressions, streams processing, and default methods.
JavaFX
8 was also released with Java8 edition,
advancing desktop Java applications more than ever. JavaFX 8 enables developing
rich desktop and Internet applications using the Java language, or any other
language that executes on the JVM. It empowers a rich set of graphical and
media user interfaces to develop extraordinary visual applications. This
release is another important update to the JavaFX platform, adding in features
such as the Swing node and the Print API.
Lambda Expressions
Java
8 has introduced a magnitude of new features, making it one of the most
significant releases of Java in years. Now we can pass functionality as a
method argument by utilizing a lambda expression to incorporate the action
functionality using compact, inline syntax. Lambda expressions are one of the new
and power packed features of Java 8 that will have a tremendous impact on
productivity and business logic. These Lambda expressions are anonymous blocks
of code that accept zero or more parameters, encapsulate a series of statements
or an expression, and return a result. They are very identical to closures
from other languages, being anonymous functions that can be passed into other
code as needed.
Date Time API
A
new Date-Time API has been introduced and added in Java 8 which was developed
under JSR 310. The Date-Time API uses the calendar defined in ISO-8601 as the
default calendar. Thus, the calendar is based on the Gregorian calendar system.
The Date-Time API adheres to several design principles in an effort to be
clear, fluent, immutable, and extensible. The API uses a clear language that is
concise and very well defined. It is also very fluent, so code dealing with date-time
data is easy to read and understand.
Streams API
Collections
play an integral role in many Java applications. The release of Java 8 introduced
the Streams API, which changes the way that collections of data can be used,
making solutions more productive and maintainable. The Streams API allows us to
traverse over a collection of elements and perform aggregate operations,
pipeline two or more operations, perform parallel execution, and more.
JavaFX
JavaFX
has undergone a massive overhaul with the release of Java 8. For starters, it is
now included with Java 8 SE, so there is no longer a need to download it
separately. Multiple new components have been added to the platform, including
a DatePicker
and new SwingNode for embedding Swing inside of JavaFX. There is also
better embedded support for deployment on platforms such as the Raspberry Pi.
Other new features include WebView enhancements, printing
support, rich text support, and the list goes on.
Scripting
The
Java platform has had support for embedding and/or executing JavaScript files
since the release of Java 1.6, and the JavaScript engine was Rhino. The Rhino
engine served us well for years, but now an updated JavaScript engine named Nashorn
has entered the scene. The Nashorn engine brings with it many updates,
including support for the ECMAScript-262 Edition 5.1 language specification, a
new command-line utility for interactive interpretation or JavaScript file
execution, and full access to the JavaFX 8 API.
Other Enhancements
Now
we can also provide a Default Method Implementation in an Interface. And, Apply
the Same Annotation Multiple Times in a Declaration or Type Use using @Repeatable.
