The general-purpose, high-level Java programming language is a powerful software platform. Every full implementation of the Java platform gives you the following features:
·
Development Tools: The development tools provide everything you'll need for
compiling, running, monitoring, debugging, and documenting your applications.
As a new developer, the main tools you'll be using are the
javaccompiler, the java launcher, and the javadoc documentation tool.
·
Application Programming Interface (API): The API provides the core functionality
of the Java programming language. It offers a wide array of useful classes ready
for use in your own applications. It spans everything from basic objects, to
networking and security, to XML generation and database access, and more. The
core API is very large; to get an overview of what it contains, consult the Java Platform Standard Edition 7 Documentation.
·
Deployment Technologies: The JDK software provides standard mechanisms such as the
Java Web Start software and Java Plug-In software for deploying your applications
to end users.
·
User Interface Toolkits: The Swing and Java 2D toolkits make it possible to create
sophisticated Graphical User Interfaces (GUIs).
Integration Libraries: Integration libraries such as the Java IDL
API, JDBC™ API, Java Naming and Directory Interface™ (JNDI) API, Java RMI, and
Java Remote Method Invocation over Internet Inter-ORB Protocol Technology (Java
RMI-IIOP Technology) enable database access and manipulation of remote objects
