Ø Object
Oriented: In
Java, everything is an Object. Java can be easily extended since it is based on
the Object model.
Ø Platform
independent:
Unlike many other programming languages including C and C++, when Java is compiled,
it is not compiled into platform specific machine, rather into platform
independent byte code. This byte code is distributed over the web and
interpreted by virtual Machine (JVM) on whichever platform it is being run.
Ø Simple: Java is designed to be easy to
learn. If you understand the basic concept of OOP, Java would be easy to
master.
Ø Secure: With Java's secure feature, it
enables to develop virus-free, tamper-free systems. Authentication techniques
are based on public-key encryption.
Ø Robust: Java makes an effort to
eliminate error prone situations by emphasizing mainly on compile time error
checking and runtime checking.
Ø Architectural-neutral: Java compiler generates an
architecture-neutral object file format, which makes the compiled code to be
executable on many processors, with the presence of Java runtime system.
Ø Portable: Being architectural-neutral and
having no implementation dependent aspects of the specification makes Java
portable. Compiler inJava is written in ANSI C with a clean portability
boundary which is a POSIX subset.
Ø Multithreaded: With Java's multithreaded
feature, it is possible to write programs that can do many tasks simultaneously.
This design feature allows developers to construct smoothly running interactive
applications.
Ø Interpreted: Java byte code is translated on
the fly to native machine instructions and is not stored anywhere. The
development process is more rapid and analytical since the linking is an
incremental and lightweight process.
Ø High
Performance:
With the use of Just-In-Time compilers, Java enables high performance.
Ø Distributed: Java is designed for the
distributed environment of the internet.
Ø Dynamic: Java is considered to be more
dynamic than C or C++ since it is designed to adapt to an evolving environment.
Java programs can carry extensive amount of run-time information that can be used
to verify and resolve accesses to objects on run-time.
