Abstract
The
upcoming release 1.5 of the Java 2 Standard Edition (J2SE) will add a number of
major and minor new language features and library extensions. The most
significant addition to the Java programming language are generic types and
methods. The most substantial addition to the Java platform libraries are the
new concurrency utilities.
Java
Generics
A common
misconception regarding generics is its comparison to C++ templates. Many
people believe that Java generics are similar to C++ templates, while in fact
both features have barely anything in common: C++ templates is a Turing
complete language - Java generics is syntactic sugar that elides some casting.
Java generics are a pure compile-time feature that is translated to non-generic
Java bytecode, for reasons of compatibility with previous versions of Java.
In this tutorial, we will take a look into the proposed language feature, how
it will help us improve our programs, how it is supposed to be used and where
its limitations are.
More specifically, we will discuss the additions made to the language itself
(parameterised types and methods as well as covariant return types), changes to
the platform libraries (generic collections and extended reflection) and
various exciting details of generics such as the properties of type parameters
(their bounds and their scope), generic methods and type parameters inference,
and the translation of generics into bytecode.
Concurrency
Utilities
The Java platform
provides basic, low-level primitives for writing concurrent programs, but they
are difficult to use properly. Many programs become clearer, shorter, faster,
easier to write, and more reliable if higher-level synchronisation constructs
are used.
A comprehensive library of concurrency utilities has been developed for
inclusion in the 1.5 release of J2SE. This library, known as the
util.concurrent package, contains thread pools, queues, concurrent collections,
special-purpose locks, barriers, and related utilities. The addition to the
Java platform is substantial and will change the way we will implement
concurrent Java applications. This tutorial gives an overview of the new
library.
Enums,
Autoboxing, etc.
Some smaller
additions to the programming language comprise syntax for enumeration types, an
enhanced for-loop, static imports, autoboxing, and varargs.
The
seminar will be held in English.
