Java is a high-level programming language developed by the sun microsystem. First, it was conceived by James Gosling, Patrick Naughton, Chris Warth, Ed Frank, and Mike in the year 1991. Initially, it was named “Oak” it was renamed as “Java” in the year 1995. Java is a highly object-oriented, platform-independent and secure programming language.
One of the most important factors in the java programming language is its Bytecode conversion. Byte codes in Java are highly optimized set of instructions designed to be executed by Java Virtual Machine. JVM works as an interpreter for the byte code.
To use java programming language we require JDK (Java Development Kit) and this includes JRE (Java Runtime Environment).
Today’s modern technology of software development java programming language provides greater advantages. Following some features of java, languages give some basic ideas about why to learn java.
Java is used in various application developments following are some real time applications of java.
public class SimpleExample1
public static void main(String args)
int a = 10;
System.out.println("Value of a = "+ a);
To learn java programming language programmer should have prior basic knowledge of any programming language such as C. Since the java is purely object oriented language basic knowledge of any object oriented language like C++ is necessary and it becomes easier to understand java. Only programmer need to understand basic syntax and structure of java programming language.
Starting from java standard edition its greater beginning for java programmers Standard Edition support to develop ranging from Desktop application to embedded systems. Advanced java version i.e. J2EE technologies support to develop Enterprise level applications, web applications, gaming applications etc….
