Java Overview

This tutorial is intended for the beginners to the programming language Java. This tutorial is split into multiple sessions. At the end of the tutorials, you will be having a basic understanding of Java programming.

What is Java?

Java is one of the most popular programming languages, developed by Sun Microsystems in the year 1991. It is initially named as “Oak” by James Gosling, one of the inventors of the Java programming language. In 1995, “Oak” is renamed to “Java” because the name “Oak” did not survive legal registration.

Java is a very powerful language and can meet all the requirements needed for the modern programming world. At the same time, it is very simple.

Advantages of Java

Some of the main advantages of Java are
1. It is object oriented
2. It is platform independent
3. It is secure
4. It is simple

Let’s look into each of these features into more detail in the coming chapters. Java helps to solve complex business requirements easily because it is object oriented. In the next chapter,we will be covering the basic Object Oriented Programming (OOP) principles which will be a very good foundation for you to start with Java.

No java is not purely OO as java have primitive variables which are against the concept of OO.

Yep, Java is pure object oriented because it doesn't consider pointer. It allocate its own memory space for storing the value.

//convert C ' into F'
//Celsius (20'c)

class hello
    public void method(int c)
        double convert = (c*9/5+32); // convert to Celsius
        System.out.println("Fahrenheit :" + convert);
    public static void main(String args [])
        hello h = new hello();
