the state of java under oracle at jcertif 2011

The State of Java

The following is intended to outline our general

product direction. It is intended for information

purposes only, and may not be incorporated into

any contract. It is not a commitment to deliver any

material, code, or functionality, and should not be

relied upon in making purchasing decisions.

The development, release, and timing of any

features or functionality described for Oracle's

products remains at the sole discretion of Oracle.

Thank you Africa!

Oracle Strategy

• Deliver a complete, open, integrated stack of

hardware, infrastructure, database, middleware, and

business applications

• Exploit processor, systems, storage, and networking

trends to deliver breakthrough innovations by combining

Oracle software with Sun hardware

• Integrate components of Oracle’s software stack to

provide unique value to customers

Open Source Strategy Comparison

Oracle doesn’t really have an open

source-specific strategy. What we

have is an overall company

strategy: to deliver complete,

open, integrated solutions to our

customers. Stacks of software and

hardware that are built together

and tested together and serviced

together. And open source is part

of that.

What's the business model? I

don't know. But if you don't

have adoption, it won't matter

what business model you

use. Companies that sell

open source are prioritizing

community and adoption

over instant monetization.

Middleware and Java in Oracle’s Strategy

• Comprehensive foundation for building and running

custom and packaged applications• Extremely well integrated

• Industry-leading reliability and performance

• Unified development and management

• Basis for Oracle Fusion applications

• Built with and for Java technology

Available Now

Java SE 7 Highlights

• JSR 334: Java language enhancements (Project Coin)

• JSR 292: New bytecode to speed dynamic languages

on the JVM

• JSR 166y: New Fork/Join framework for concurrent

programming

• JSR 203: NIO.2

String in Switch – Before JDK 7

@Path("fruits")

public class FruitResource {

@GET

@Produces("application/json")

@Path("{name}")

public String getJson(@PathParam("name")String name) {

if (name.equals("apple") || name.equals("cherry") || name.equals("strawberry"))

return "Red";

else if (name.equals("banana") || name.equals("papaya"))

return "Yellow";

else if (name.equals("kiwi") || name.equals("grapes") || name.equals("guava"))

return "Green";

else if (name.equals("clementine") || name.equals("persimmon"))

return "Orange";

else

return "Unknown";

}

. . .

String in Switch – After JDK 7

@Path("fruits")

public class FruitResource {

@GET

@Produces("application/json")

@Path("{name}")

public String getJson(@PathParam("name")String name) {

switch (name) {

case "apple": case "cherry": case "strawberry":

return "Red";

case "banana": case "papaya":

return "Yellow";

case "kiwi": case "grapes": case "guava":

return "Green";

case "clementine": case "persimmon":

return "Orange";

default:

return "Unknown";

}

}

Automatic Resource Management – Before JDK 7

@Resource(name=“jdbc/__default”)

DataSource ds;

@javax.annotation.PostConstruct

void startup() {

Connection c = null;

Statement s = null;

try {

c = ds.getConnection();

s = c.createStatement();

// invoke SQL here

} catch (SQLException ex) {

System.err.println("ouch!");

} finally {

try {

if (s != null)

s.close();

if (c != null)

c.close();

} catch (SQLException ex) {

System.err.println("ouch!");;

}

}

}

Automatic Resource Management – After JDK 7

@Resource(name=“jdbc/__default”)

DataSource ds;

@javax.annotation.PostConstruct

void startup() {

try (Connection c = ds.getConnection(); Statement s = c.createStatement()) {

// invoke SQL here

} catch (SQLException ex) {

System.err.println("ouch!");

}

}

Multi-catch – Before JDK 7

out.println("</body>");

out.println("</html>");

} catch (ServletException ex) {

Logger.getLogger(TestServlet.class.getName()).log(Level.SEVERE, null, ex);

} catch (MessagingException ex) {

Logger.getLogger(TestServlet.class.getName()).log(Level.SEVERE, null, ex);

} catch (IOException ex) {

Logger.getLogger(TestServlet.class.getName()).log(Level.SEVERE, null, ex);

} finally {

out.close();

}

Multi-catch – After JDK 7

out.println("</body>");

out.println("</html>");

} catch (ServletException | MessagingException | IOException ex) {

Logger.getLogger(TestServlet.class.getName()).log(Level.SEVERE, null, ex);

} finally {

out.close();

}

Late 2012

• Project Lambda

• Annotations on Java types

Java SE 8 Projects

JDK 8 – Fall/Winter 2012

• Platform Modularization

• Project Lambda

• Lambda Expressions

• Default Methods

• Bulk Data Operations

• Annotations on Java types (JSR 308)

• More Small Language Enhancements

• Improved language interop

• Faster startup/warmup

• Dependency injection (JSR 330)

• Include select enhancements from Google Guava

• Small Swing enhancements

• More security/crypto features, improved support for x.509-style certificates etc

• Internationalization: non-Gregorian calendars, more configurable sorting

• Date and Time (JSR 310)

• Process control API

Other Things On Oracle’s Wish List*

* Many of these will undoubtedly NOT make JDK 8.

OpenJDK Momentum
