what is java –
Java is a programming language and a platform. Java is a high level,
robust, object-oriented and secure programming language.
history of java –
Java was developed by Sun Microsystems (which is now the subsidiary of
Oracle) in the year 1995 and released 23 January 1996. The first version of
java was JDK 1.0 and latest version of java 17.0.2
James Gosling is known as the father of Java. Before Java, its name was
Oak. Since Oak was already a registered company, so James Gosling and his
team changed the name from Oak to Java. The team of java called green team
and the first program name was Greentalk which is created by James
Gosling
features of java –
Object – Oriented – Java is a pure Object Oriented Programming Language
(OOPs). Procedures are not used in it but it is only Object
based language. Java follows the concept of OOPs which
simplifies the work of software development and
maintenance.
Java is Platform Independent Language. It runs in every
platform like Android, Windows, Linux and Mac. Programs
written in Java can be run in any operating system, such
as if Java’s program is written in Windows OS, then we will
be able to run it easily in Linux OS as well.
Another great feature of Java is that it is a secure language.
Java is the most secure because the Java program runs in the
Java Run Time Environment, before generating the machine
code, the program detects the error by running some tests on
the JVM. The Java language is virus free, which keeps the
programs safe.
