5 JDK 8 Conceptual Overview 5 Copyright 2015, Oracle and/or its affiliates. All rights reserved.

6 Java SE 8 Biggest changes to the Java language since Java SE 5 Significant enhancements in the class libraries The main goals of these changes are: Better developer productivity More reliable code Better utilisation of multi-core and multi-processor systems Code is no longer inherently serial or parallel 6 Copyright 2015, Oracle and/or its affiliates. All rights reserved.

8 Lambda Expressions Closures and Functional Programming Lambda expressions provide anonymous function types to Java Replace use of anonymous inner classes Provide more functional style of programming in Java dosomething(new DoStuff() { public boolean isgood(int value) { return value == 42; } }); Simplified to: dosomething(answer -> answer == 42); 8 Copyright 2015, Oracle and/or its affiliates. All rights reserved.

9 Extension Methods Bringing Multiple Inheritance (of Functionality) to Java Provide a mechanism to add new methods to existing interfaces Without breaking backwards compatability Gives Java multiple inheritance of behaviour, as well as types (but not state!) public interface Set<T> extends Collection<T> { public int size();... // The rest of the existing Set methods } public T reduce(reducer<t> r) default Collections.<T>setReducer; 9 Copyright 2015, Oracle and/or its affiliates. All rights reserved.

10 Annotations On Java Types Before Java 8 annotations clould only be used on type declarations Classes, methods, variable definitions Extension for places where types are used e.g. parameters, generics, casts Permits error detection by pluggable type checkers e.g. null pointer errors, race conditions, String data; List<@NonNull String> strings; mygraph = (@Immutable Graph) tmpgraph; 10 Copyright 2015, Oracle and/or its affiliates. All rights reserved.

11 Access To Parameter Names At Runtime Reflection API extension Mechanism to retrieve parameter names of methods and constructors At runtime via core reflection Improved code readability Eliminate redundant annotations Improve IDE capabilities Auto-generate template code 11 Copyright 2015, Oracle and/or its affiliates. All rights reserved.

12 Small Things Repeating annotations Multiple annotations with the same type applied to a single program element No more apt tool and PARTNUM PARTREV ) public Part getpart() { return part; } Complete the transition to the JSR 269 implementation DocTree API Provide access to the syntactic elements of a javadoc comment DocLint tool Use DocTree API to identify basic errors in javadoc comments 12 Copyright 2015, Oracle and/or its affiliates. All rights reserved.

13 Enhance Core Libraries With Lambdas No small task! Java SE 7 has 4024 standard classes Modernize general library APIs Improve performance Gains from use of invokedynamic to implement Lambdas Demonstrate best practices for extension methods 13 Copyright 2015, Oracle and/or its affiliates. All rights reserved.

14 Bulk Data Operations For Collections Java Streams API: Filter, Map, Reduce for Java java.util.function package Function, Predicate, Consumer, Supplier interfaces java.util.stream package Stream, Collector interfaces Hidden implicit iteration Serial and parallel implementations Generally expressed with Lambda statements Parallel implementation builds on Fork-Join framework Lazy evaluation 14 Copyright 2015, Oracle and/or its affiliates. All rights reserved.

15 Source Stream Java Streams API Intermediate Stream Intermediate Stream filter map max Result Higher abstraction view on Collections Uses the Unix concept of pipes and filters No storage Functional in nature Seeks laziness List<Person> persons =... int oldestpeter = persons.stream().filter(p -> p.getname() == Peter ).map(p -> p.getage()).max(); 15 Copyright 2015, Oracle and/or its affiliates. All rights reserved.

16 Source Stream Java Streams API Intermediate Stream List<Person> persons =... int oldestpeter = persons.parallelstream() 16 Copyright 2015, Oracle and/or its affiliates.

17 Date And Time APIs A new date, time, and calendar API for the Java SE platform Supports standard time concepts Partial, duration, period, intervals date, time, instant, and time-zone Provides a limited set of calendar systems and be extensible to others Uses relevant standards: ISO-8601, CLDR, and BCP47 Based on an explicit time-scale with a connection to UTC 17 Copyright 2015, Oracle and/or its affiliates. All rights reserved.

18 Base64 Encoding and Decoding Currently developers are forced to use non-public APIs sun.misc.base64encoder sun.misc.base64decoder Java SE 8 now has a standard way java.util.base64.encoder java.util.base64.decoder encode, encodetostring, decode, wrap methods 18 Copyright 2015, Oracle and/or its affiliates.

22 Modularisation Preparation Getting Ready For Jigsaw Fix some assumptions about classloaders Use ServiceLoader rather than proprietary SPI code E.g. JAXP does not use ServiceLoader JDK tool to analyse application code dependencies: jdeps Deprecate APIs that will impede modularisation e.g. java.util.logging.logmanager.addpropertychangelistener 22 Copyright 2015, Oracle and/or its affiliates. All rights reserved.

23 Lambda Representation for Method Handles Assembly language code re-written in Java Improve performance, quality, and portability of method handles and invokedynamic Reduce the amount of assembly code in the JVM Reduce native calls during method handle processing Better reference implementation of JSR 292 (invokedynamic) 23 Copyright 2015, Oracle and/or its affiliates.

29 New and changed deployment features in JDK 8 Enhancements in JDK 8u20 The JavaFX Packager tool is renamed to Java Packager and is run with the javapackager command. Support for self-contained applications is expanded to enable arguments to be passed to the bundlers that are used to generate the native installable packages Chapter 7, "Self-Contained Application Packaging The Medium security level has been removed. Only High and Very High are supported Section , "Security Level For enterprise customers who use the Deployment Rule Set, the attribute force is available for the action element. When this attribute is set to true, the JRE version requested by any RIA that matches the rule is overridden and the RIA is run with the version of the JRE that is specified in the rule 29 Copyright 2015, Oracle and/or its affiliates.

30 Enhanced Certificate Revocation Checking API Former java.security.cert API is all-or-nothing Failure to contact server is a fatal error New classes RevocationChecker RevocationParameters Online certificates checking during runtime with online certificate status protocol OCSP under the hood Both is used, and both can be turned off or on. Turning OCSP on with a non-networked system may be slower because it could wait to connect. Similar story with CA s who have slow OCSPs. We test and validate them before inclusion. CA s whose OCSP is not turned on, do not get accepted What s the best way to work offline with certificates and verify them, e.g. to maintain the certificate revocation list as CRL offline? For offline validation, the easiest best is to just periodically grab the CRL. The CA s update those periodically, about once a week. You should be able to locate either the CRL and/or OCSP through the certificate s Authority Info Access All this is controlled either in the control panel or java.security 30 Copyright 2015, Oracle and/or its affiliates.
