Advance Java Programming: Java Buzzwords

The Java programming language is a high-level language that can be characterized by all of the following buzzwords:

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.

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:

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.

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.

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.

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.

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.

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.

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

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.

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.
