You Know about JAVA programming language and about its execution flow and also history ?

JAVA is a platform-independent programming language that base is C++ language.

It is the Object-Oriented Programming Language which means we

can use the “Bottom-up Approach” to develop software or a program.

In JAVA all the work or programs or codes is written in a class and

a single program or one software contains only one main class is

compulsory because the main class contains the main method

where execution is started by JVM.

History of JAVA

“JAVA was developed by James Gosling in 1995”. JAVA uses the

the base of C++ language but some things that are not used in JAVA

because of security issues like pointers, operator overloading,

garbage collection, C++ Header files, Destructor, Multiple

inheritance.

JAVA has a more secure language and also a Platform independent

means we can write any code or programs after compile means

generating byte codes of this code or programs using Compilation

of these programs(javac) then we can execute this byte codes in any

platform means we can write a program in a window machine but

we can able to run this program in a Linux platform or any platform

because byte code is platform dependent but not program so we

can execute this bytecode on the platform related JVM(JAVA

VIRTUAL MACHINE).

JVM is responsible to execute JAVA programs in an efficient manner and control all the aspects and provide the required resources of Programs.

JAVA was first named Oak but now JAVA.

JAVA provides ready-made containers that are contributed by someone developer that is Collection Framework.

If we define all the aspects of JAVA language-related then we and you are not able to define in a single page or one hour or one months or one year because JAVA is most huge or big programming language that covers all the aspect of IT Industry like web development, software development, android development, also embedded system, etc.
