2. Introduction to Java.
A small history of Java : Java is a programming language created by James
Gosling from Sun Microsystems (Sun) in 1991. The target of Java is to write
a program once and then run this program on multiple operating systems.
The first publicly available version of Java (Java 1.0) was released in 1995.
Sun Microsystems was acquired by the Oracle Corporation in 2010. Over
time new enhanced versions of Java have been released. The current version
of Java is Java 1.8 which is also known as Java 8.
3. Hello world Java program :
// a small Java program public class HelloWorld {public static void
main(String[] args)
{ System.out.println("Hello World"); }
4. 3. Java virtual machine : The Java virtual machine (JVM) is a
software implementation of a computer that executes programs like a
real machine.
The Java virtual machine is written specifically for a specific
operating system, e.g., for Linux a special implementation is required
as well as for Windows.
6. 1. What is Core Java.
Core Java usually refers to Java SE which consists of the Java
Language, the JVM and JDK (which itself contains the compiler
some tools and a pretty large library). Core Java is used for general
purpose programming and almost anything written in Java is based
on the Core Java.
7. 2. What is advanced Java?
The 'Advanced Java' comprises the very complex advanced
programming. The advanced java programming covers the Swings,
Socket Programming, AWT, Thread Concepts as well as the Collection
objects and classes. "Advanced Java" is nothing but specialization in
domains such as web, networking, data base handling.
8. 3. What is Java Framework ?
The Java collections framework (JCF) is a set of classes and interfaces that
implement commonly reusable collection data structures. Although referred
to as a framework, it works in a manner of a library. The JCF provides both
interfaces that define various collections and classes that implement them.
