Java Buzzwords

• Object Oriented: In Java, everything is an Object. Java can be easily extended since it is based on the Object model. It does not even allow any method outside a class. Even main method is inside a class compulsorily.
• 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. 
   
• Simple:Java is designed to be easy to learn. If you understand the basic concept of OOP Java would be easy to master. All complex features of C/C++ are eliminated. And idea was to make the language as simple as possible.
  
• Secure:  With Java's secure feature it enables to develop virus-free, tamper-free systems.Java has an inbuilt Security Manager which is responsible for security of java applications at runtime. Java also provides a lot of security tools like key tools, policy tool and jar signer as part of jdk useful to develop secure applications
• 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.
• Portable:Being architectural-neutral and having no implementation dependent aspects of the specification makes Java portable. Compiler in Java is written in ANSI C with a clean portability boundary which is a POSIX subset.
• Robust:Java makes an effort to eliminate error prone situations by emphasizing mainly on compile time error checking and runtime checking. Robustness is about having a code that runs for longer times without errors.
• 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. Java provides easy facility for developers to develop multi threaded applications which would be otherwise very difficult in other programing languages.
• Interpreted:Java byte code is translated on the fly to native machine instructions and is not stored anywhere. Compiler compiles java code. This compiled code is converted on the fly into native code. This process is called as interpretation. It makes java execution slow (marginally)
• High Performance: With the use of Just-In-Time compilers, Java enables high performance.
• Distributed:Java is designed for the distributed environment of the internet.
• 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.
