Java SE 8

• Nearly four years in the making

• Biggest upgrade to Java programming model ever!

• Small set of features, with a big impact

• Lambda Expressions

• Default Methods

• Bulk Operations on Collections

• Coordinated co-evolution of language, libraries, and

VM


Java 8 for the Java Developer Community • Productivity & Performance

• Project Lambda makes it easier to distribute processing of collections over multiple threads (better application

performance and simpler code).

• Productivity features enable developers to write more readable and shorter code with improved collections and

annotations.

• Modularity – Java SE Compact Profiles & Java ME as a subset of the Java SE platform

• Profiles for Java SE large, medium and small footprint enables more efficient deployments

• Embedded application development made easier for Java developers – Java ME updated with VM, Java Language, and

Libraries, and features to be aligned with Java SE 8 while retaining the focus on small embedded devices.

• Java developers are uniquely positioned to drive innovation for Mobile, Social, IoT & Cloud

• Open, standards-based, community-driven platform, spanning from small devices to cloud-based development,

combined with Java developers’ talent will make IoT a reality

• Java developers have incredible opportunity can transfer their skills and knowledge to develop robust and highly

performant applications from edge devices through to the enterprise.

• Java is a community technology

• JCP is important, it's growing, it's working - JDK 8 and Java ME 8 were developed with community participation


Java 8 for the Enterprise and IoT • Java 8 enables significant productivity and performance enhancements

• Java SE 8 contains numerous new features and enhancements that deliver application performance benefits and simpler

parallel programming models

• JDK 8 enables developers to be more productive with simpler and more readable code

• Java 8 is the platform of choice for the Internet of Things, Mobile, Social & Cloud – all of

your services can be implemented in Java from the edge device to the data center.

• Harness the opportunity to use your existing and readily available developer talent to implement your IoT strategy.

• Reduce costs while driving innovation and improving services (Reduce Complexity, Drive Innovation, Create Opportunity)

• Java is the path to platform standardization for embedded environments.

• Support any device, any size, any market – Java fills the void of no standards for embedded device application development.

• Java SE and Java ME are on a strong convergence path

• Time to Market with an integrated, end-to-end platform, it is possible to deploy applications faster, process and analyze

in-flight data at lightning speeds and act on events as quickly as they occur – ROI & improved services.

• Innovation there are 9 million Java developers worldwide, allowing businesses to take advantage of readily available

developer talent to bring products and solutions to market faster.

“Java SE 8 is about taking advantage of new parallel architectures. Lambda, the key feature, opens the door for a new style of development that can lead to more parallelism and other capabilities like the Streams API are about parallel processing as well. The changes are significant for the community and for improving code quality everywhere in the long run.”
