Java Buzzwords or Features of Java

The Java programming language is a high-level language that can be characterized by all of the following buzzwords:
  1. Simple
  2. Object-oriented
  3. Distributed
  4. Interpreted
  5. Robust
  6. Secure
  7. Architecture neutral
  8. Portable
  9. High performance
  10. Multithreaded
  11. Dynamic

1. Simple

  • Java was designed to be easy for a professional programmer to learn and use effectively.
  • It’s simple and easy to learn if you already know the basic concepts of Object Oriented Programming.
  • Best of all, if you are an experienced C++ programmer, moving to Java will require very little effort. Because Java inherits the C/C++ syntax and many of the object-oriented features of C++, most programmers have little trouble learning Java.
  • Java has removed many complicated and rarely-used features, for example, explicit pointers, operator overloading, etc.

2. Object Oriented

  • Java is true object-oriented language.
  • Almost “Everything is an Object” paradigm. All program code and data reside within objects and classes.
  • The object model in Java is simple and easy to extend.
  • Java comes with an extensive set of classes, arranged in packages that can be used in our programs through inheritance.
  • Object-oriented programming (OOPs) is a methodology that simplifies software development and maintenance by providing some rules.
Basic concepts of OOPs are:
  • Object
  • Class
  • Inheritance
  • Polymorphism
  • Abstraction
  • Encapsulation

3. Distributed

  • Java is designed fa or distributed environment of the Internet. Its used for creating applications on networks.
  • Java applications can access remote objects on the Internet as easily as they can do in the local system.
  • Java enables multiple programmers at multiple remote locations to collaborate and work together on a single project.
  • Java is designed for the distributed environment of the Internet because it handles TCP/IP protocols.

4. Compiled and Interpreted

  • Usually, a computer language is either compiled or Interpreted. Java combines both this approach and makes it a two-stage system.
  • Compiled: Java enables the creation of cross-platform programs by compiling into an intermediate representation called Java Bytecode.
  • Interpreted: Bytecode is then interpreted, which generates machine code that can be directly executed by the machine that provides a Java Virtual machine.

5. Robust

  • It provides many features that make the program execute reliably in a variety of environments.
  • Java is a strictly typed language. It checks code both at compile time and runtime.
  • Java takes care of all memory management problems with garbage collection.
  • Java, with the help of an exception handling, captures all types of serious errors and eliminates any risk of crashing the system.

6. Secure

  • Java provides a “firewall” between a networked application and your computer.
  • When a Java Compatible Web browser is used, downloading can be done safely without fear of viral infection or malicious intent.
  • Java achieves this protection by confining a Java program to the Java execution environment and not allowing it to access other parts of the computer.

7. Architecture Neutral

  • Java language and Java Virtual Machine helped in achieving the goal of “write once; run anywhere, any time, forever.”
  • Changes and upgrades in operating systems, processors and system resources will not force any changes in Java Programs.

8. Portable

  • Java Provides a way to download programs dynamically to all the various types of platforms connected to the Internet.
  • It helps in generating Portable executable code.

9. High Performance

  • Java performance is high because of the use of bytecode.
  • The bytecode was used so that it was easily translated into native machine code.

10. Multithreaded

  • Multithreaded Programs handled multiple tasks simultaneously, which was helpful in creating interactive, networked programs.
  • Java run-time system comes with tools that support multiprocess synchronization used to construct smoothly interactive systems.

11. Dynamic

  • Java is capable of linking in new class libraries, methods, and objects.
  • Java programs carry with them substantial amounts of run-time type information that is used to verify and resolve accesses to objects at runtime. This makes it possible to dynamically link code in a safe and expedient manner.
