Course Overview
Free Online Java Training
Java is simple and very powerful programming language which is based on OOPs concepts. Java was settled by James Gosling and Patric, Naugton, at Sun Micro System. The original name of JAVA was OAK (which is a tree name). In 1995, OAK was brush up and developed software called JAVA (which is a coffee bean). JAVA is very famous among other languages just because of its features. WORA is one of the famous features of java that stands for Write Once, Run Anywhere. This is possible because of JVM that is Java Virtual Machine.
When source code is compile “.java files”, it is internally converted into byte codes and then JVM convert that to (class file). The JVM executes these byte codes. So Java byte codes can be run as the machine language of the JVM. JVM can either interpret the bytecode one instruction at a time or the bytecode can be compiled further for the real microprocessor using just-in-time compiler. The JVM must be executed on a specific platform before compiled programs can run on that platform.
The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.
The original and reference implementation Java compilers, virtual machines, and class libraries were originally released by Sun under proprietary licenses.
JAVA introduced three categories that are J2SE (JAVA 2 Standard Edition), J2EE (JAVA 2 Enterprise Edition) and J2ME (JAVA 2 Micro/Mobile Edition).
• J2SE is services for building standalone application/programs development.
• J2EE is services for building client server applications/programs development.
• J2ME is services for building Mobile Application/programs development.
These are some features of JAVA:
• Java does not depend on platform to run it code:
Java programs executes in JRE (Java Runtime Environment) provided by Java virtual machine so java program is not accessible to operating system directly. This whole system makes Java programs platform independent.
• Java is based on OOPS concepts that is Object-Orientated Programming language :
Except the basic data types, it fallows all the concepts of Object Oriented Programming Language.
• Java is type-specific programming language:
Java is toughly typed-specific, means variables must be declared to have a specific type of data.
• Java Interprets the code and then compiles:
Java source code is conveyed into the byte code, which does not depend on any particular platform. These byte codes will be ran by the JVM (Java Virtual machine).
• Java support garbage collection which de-allocates the junk memory :
Java handles the memory allocation and de-allocation for creating new objects. Garbage collector automatically removes objects to which no active thread/process is executing. JVM will call garbage collector whenever system require some free memory or not enough to run that application.
• It is comprehensively secure: java application executes inside special environment created by JVM (Java Runtime Environment) that is JRE. So no-one can directly access application code or interfere in application.
• Simple: Java is easy to learn after learning C language because java concepts and syntax are similar to C language. Java remove composite Concept of C and C++ language like operator overloading, Pointer etc.
• Java support Multithreading Environment: Java allows you to write programs that do many things simultaneously. Multithreading is mostly used in gaming, animation etc.
