JSDK

• Java SDK - Software Development Kit
  (http//java.sun.com/j2se/downloads/) contiene
  J2SE Runtime Environment (JRE) and J2SE
  Development Kit (JDK).
• compilatore Java
• debugger
• interprete Java
• Versione J2SE v 1.4.2_09 SDK

• Contents
• - J2SE API
• - Java Virtual Machine
• - Java Platform Tools
• There are two principal products in the J2SE
  platform family J2SE Runtime Environment (JRE)
  and J2SE Development Kit (JDK). The JRE provides
  the Java APIs, Java virtual machine, and other
  components necessary to run applets and
  applications written in the Java programming
  language. It is also the foundation for the
  technologies in the Java 2 Platform, Enterprise
  Edition (J2EE) for enterprise software
  development and deployment. The JRE does not
  contain tools and utilities such as compilers or
  debuggers for developing applets and
  applications. The JDK is a superset of the JRE,
  and contains everything that is in the JRE, plus
  tools such as the compilers and debuggers
  necessary for developing applets and
  applications. By http//java.sun.com/j2se/overvi

• J2SE API
• The J2SE application programming interface (API)
  defines the prescribed manner by which an applet
  or application can make requests to and use the
  functionality available in the compiled J2SE
  class libraries. The J2SE class libraries are
  also part of the J2SE platform. The J2SE API
  consists of technologies we have organized into
  two groups Core Java and Desktop Java.
• Core Java provides essential functionality for
  writing powerful enterprise-worthy programs in
  key areas such as database access, security,
  remote method invocation (RMI), and
  communications, to name a few.
• Desktop Java provides a full range of features to
  help build desktop applications that provide a
  rich user experience. Desktop Java consists of
  deployment products such as Java Plug-in,
  component modeling APIs such as JavaBeans,
  graphical user interface (GUI) APIs such as the
  Java Foundation Classes (JFC) and Swing, and
  multimedia APIs such as Java3D.
• To learn more about Java Desktop, visit the
  Desktop Java community collaboration site and
  java.com consumer site. For information on how to
  use the J2SE APIs, refer to the API (Javadocs)
  and technical documentation.

• Java Virtual Machine
• The Java Virtual Machine is responsible for the
  hardware- and operating system-independence of
  the J2SE platform, the small size of compiled
  code (bytecodes), and platform security.
• Java Platform Tools
• The J2SE platform works with an array of tools,
  including Integrated Development Environments
  (IDEs), performance and testing tools, and
  performance monitoring tools.

Java API Documentation

• E la documentazione delle API Java. Dal sito può
  essere scaricata la documentazione delle API
  della libreria standard Java.
• J2SE v 1.4.2 Documentation

Gli IDE

• GLI IDE (Integrated Software Enviroment) sono
  ambienti di sviluppo integrati che mettono
  insieme Editor, compilatore, interprete,
  debugger, documentazione, ecc. in una unica
  soluzione.
• Nel corso utilizzeremo NetBeans IDE 3.6
• http//www.netbeans.org
• http//www.netbeans.info/downloads/download.php?a
