Getting started with IDE
IDE
(Integrated Development Environment)
An integrated
development environment (IDE) (also known as integrated design
environment, integrated debugging environment or interactive
development environment) is a software application that provides
comprehensive facilities to computer programmers for software
development. An IDE normally consists of:
A
source code editor
Build
automation tools
A
debugger
Some
IDEs contain compiler and/or an interpreter, such
as Microsoft Visual Studio and Eclipse; others do not, such
as Sharp Develop and Lazarus.
Programming
using IDE
Using an Integrated Development Environment (IDE) for developing
applications saves you time by managing windows, settings, and data. In
addition, an IDE can store repetitive tasks through macros and abbreviations.
Drag-and-drop features make creating graphical user interface (GUI) components
or accessing databases easy, and highlighted code and debugging features alert
you to errors in your code.
The
NetBeans IDE is open source and is written in the Java programming language. It
provides the services common to creating desktop applications -- such as window
and menu management, settings storage -- and is also the first IDE to fully
support JDK 6.0 features. The NetBeans platform and IDE are free for commercial
and noncommercial use, and they are supported by Sun Microsystems.
·
RAD: Rapid
Application Development is software programming technique that allows quick development
of software application.
·
Integrated
Development Environment (IDE): It is a software
tool to help programmer to edit, compile, interpret and debug the
program in the same environment. i.e Eclipse,NetBeans, VB etc.
·
Byte code: A byte
code is machine instruction that the Java compiler generates and Java interpreter
executes. When the compiler compiles a .java file, it produces a series of byte
codes and stores them in a .class file. The Java interpreter (JVM) can execute
the byte codes stored in the .class file.
·
JVM: Java
Virtual Machine (JVM) is a program which behaves as interpreter and translates
the byte code into machine language as they go called just in time
compilation.
·
Source
Code: The core program or text which is written in a
language like C,C++ or Java is called source code.
·
Object
Code: The program which only is understood by the
computer in the form of machine instructions or binary instructions
called object code. In Java JVM is used to generate object code in the form of
byte code.
·
GUI: A
graphical user interface (GUI) presents a pictorial interface to a program. GUI
allows the user to spend less time trying to remember which keystroke
sequences do what and spend more time using the program in a productive manner.
