Some word about Java language
This site is providing tutorials about java language and much more.Java language is a General purpose computer programming language that is concurrent, class-based, object-oriented and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture. As of 2017, Java is one of the most popular programming languages in use particularly for client-server web applications, with a reported millions of developers. Java was originally developed by James Gosling at Sun Microsystems(which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.
History of java language
To fully understand Java,
one must understand the reasons behind its creation, the forces that shaped it,
and the legacy that it inherits. Like the successful computer languages that
came before, Java is a blend of the best elements of its rich heritage combined
with the innovative concepts required by its unique mission. While the
remaining chapters of this book describe the practical aspects of
Java including its syntax, key libraries, and applications this chapter
explains how and why Java came about, what makes it so important, and how it
has evolved over the years.
Although Java has become inseparably linked
with the online environment of the Internet, it is important to remember that
Java is first and foremost a programming language. Computer language innovation
and development occurs for two fundamental reasons: To adapt to changing
environments and uses To implement refinements and improvements in the art of
programming
As you will see, the development
of Java was driven by both elements in nearly equal measure. Java’s Lineage
Java is related to C++, which is a direct descendant of C. Much of the
character of Java is inherited from these two languages. From C, Java derives
its syntax. Many of Java’s object-oriented features were influenced by C++.
In fact, several of Java’s defining
characteristics come from—or are responses to—its predecessors. Moreover, the
creation of Java was deeply rooted in the process of refinement and adaptation
that has been occurring in computer programming languages for the past several
decades. For these reasons, this section reviews the sequence of events and
forces that led to Java. As you will see, each innovation in language design
was driven by the need to solve a fundamental problem that the preceding
languages could not solve. Java is no exception
