Basics of Java Technology
This section provides an overview of Java technology as
programming language and a platform. Java technology is a simple, secure,
robust, complete object oriented and platform independent high level
programming language. It is also
portable, high performance, multi threaded and networks that enable it in constructing software that
can run along in small machines. The
whole technology is based on the concept of Java Virtual Machine (JVM) that
acts as a translators of byte code into
machine language. In other words JVM converts the java byte codes into platform
specific machine language.
Understanding the Java Technology
Java technology is high-level, object-oriented, very robust
programming language. Java is platform independent programming language and you
can run your compiled code on any operating system without recompiling your
source code. Java technology is based on the concept of a single Java virtual
machine (JVM) -- a translator between the language and the underlying software
and hardware. All implementations of the programming language must emulate the
JVM, enabling Java programs to run on any system that has a version of the JVM.
If you want to start java programming then you need to use a
text editor to create and edit the source code.
By using the Java complier, you can change the source code into byte
code. The byte code can be run on any platform having Java interpreter that can
convert the byte code into codes suitable for the operating system.
