Project Coin – JSR 334 http://www.flickr.com/photos/chefranden/908539119/ 11

Coin (1) Strings in switchString s = ...switch(s) {case "foo": processFoo(s); break;} 12

Coin (2) Changes to literals• 1234_5678• 1_2_3_4__5_6_7_8L• 0b0001_0010_0100_1000• 3.141_592_653_589_793d• 0x1.ffff_ffff_ffff_fP1_023 // Double.MAX_VALUE 13

Coin (3) Multi Catchtry { try { doWork(file); doWork(file);} catch (IOException ex) { } catch (IOException|SQLException logger.log(ex); ex) { logger.log(ex);} }catch (SQLException ex) { logger.log(ex);} 14

Coin (4) Diamond operatorMap<String,List<String>> m = new HashMap<String,List<String>>();Map<String,List<String>> m = new HashMap<>(); 15

Coin (5) Try with resourcestry (AutoclosableResource) {// Do stuff}// closed here 16

Concurrency and Collections Updates - JSR 166yLightweight Fork/Join Framework10,000,0001,000,000 Transistors (1,000s) 100,000 10,000 1,000 Clock (MHz) 100 10 1 1970 1975 1980 1985 1990 1995 2000 2005 2010 17

Network and File System – JSR 203NIO.2• NIO.2• NIO.2 file system Provider for ZIP and JAR Archives• SCTP (Stream Control Transmission Protocol)• SDP (Sockets Direct Protocol)• (New) Enhanced JMX agent and MBeans 18

Security• Native ECC (Elliptic Curve Cryptography)• ASLR (Address space layout randomization)• DEP (Data Execution Prevention) – Windows Only 19

Internationalization• Unicode 6.0• IETF BCP47 and UTR35 – One language many character codes – Three-letter base language codes• Separate user locale and user interface locale 20

Other Enhancements• JAXP 1.4.4• JAXWS 2.2• JAXB 2.2• JDBC 4.1• Rowset 1.1• Javadoc support for stylesheets 21

JDK 7 Platform Support• Windows x86 – Server 2008, Server 2008 R2, 7 & 8 (when it GAs) – Windows Vista, XP• Linux x86 – Oracle Linux 5.5+, 6.x – Red Hat Enterprise Linux 5.5+, 6.x – SuSE Linux Enterprise Server 10.x, 11.x – Ubuntu Linux 10.04 LTS, 11.04• Solaris x86/SPARC – Solaris 10.9+, 11.x• Apple OSX x86 – will be supported post-GA, detailed plan TBDNote: JDK 7 should run on pretty much any Windows/Linux/Solaris. 22

JDK 8 – Fall/Winter 2012 Features from “Plan B” Other Things On Oracle’s Wish List* • Modularization • Serialization fixes • Multicast improvements • Language and VM Support • Java APIs for accessing location, • Platform Modularization compass and other ”environmental” data (partially exists in ME) • Project Lambda • Improved language interop • Lambda Expressions • Faster startup/warmup • Default Methods • Dependency injection (JSR 330) • Bulk Data Operations • Include select enhancements from Google Guava • Annotations on Java types (JSR 308) • Small Swing enhancements • More Small Language Enhancements • More security/crypto features, improved • Project Coin part 2 support for x.509-style certificates etc • Internationalization: non-Gregorian calendars, more configurable sorting • Date and Time (JSR 310) • Process control API * Many of these will undoubtedly NOT make JDK 8. 23

Java EE Developer 24

The Cloud is Making Developers Restless• Enterprise developers want cloud solutions from their own IT – IT provides the SLA – Developers want: • Hosted cloud services • On-demand provisioning • Reliable scale• Virtualization is a valuable tool• Java EE has solved similar challenges for enterprises in the past 25

Today’s Cloud Offerings Are Vendor-SpecificInfrastructure as Platform as Software asa Service a Service a Service … 26

Core Java EE7 specification work• Leverage solid EE6 Uptake and Developer Reception• EE7 Underway with Broad Industry Participation – New Caching and Data Grid APIs – New JMS Includes Simplified Programming Model and Cloud Enablement – Expanded REST Support with Client API, Filters, Validation – Multi-Tenancy Awareness Across the Platform – Dependency Injection More Integrated and Unified Across Java EE 27

Java EE for the Cloud : JSR 342• Evolution, not revolution• More easily operate on private/public clouds – Multi-tenancy – Elasticity• Better isolation between applications• Potential standard APIs for Caching, etc.• Common management and monitoring interfaces• Better packaging 28
