4. 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

16. 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
Available Now

17. 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";
}
. . .

18. 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";
}
}
. . .

19. 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!");;
}
}
}

20. 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!");
}
}

21. 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();
}

22. 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();
}

23. Java SE 8 Projects
• Project Lambda
– Lambda expressions
– Interface evolution
– Concurrent bulk data operations
• Modularity for Java SE
• Careful additions to the Java language
Late 2012 • Annotations on Java types

24. 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, compass and other
• Platform Modularization ”environmental” data (partially exists in ME)
• Improved language interop
• Project Lambda
• Faster startup/warmup
• Lambda Expressions • Dependency injection (JSR 330)
• Default Methods • Include select enhancements from Google Guava
• Small Swing enhancements
• Bulk Data Operations
• More security/crypto features, improved support for
• Annotations on Java types (JSR 308) x.509-style certificates etc
• Internationalization: non-Gregorian calendars, more
• More Small Language Enhancements configurable sorting
• Project Coin part 2 • Date and Time (JSR 310)
• Process control API
* Many of these will undoubtedly NOT make JDK 8.
