It's not a secret how technology is advancing at a rapid rate. More powerful software programming languages are being released every day. Therefore it's crucial to stay on top with the latest knowledge. TechGig is providing tutorials on various technologies and one of them is Java tutorial. Java is a programming language and it is also a platform.

Here's just some of what you'll learn?

Java is one of the most popular programming languages used to create web applications and platforms. The core advantage of using Java as a language is its attribute of flexibility enabling programmers to develop code that would work on any system irrespective of the platform. According to research, more than 1 billion computers and 3 billion mobile phones worldwide run Java. Java being an Object Oriented Programming language is yet another reason behind its never ending popularity. Developing OOP'S application is much easier, and it also helps to keep system modular, flexible and extensible.

TechGig has specifically prepared this tutorial to guide beginners grasp the varying concepts of Java right from the scratch to advance level programming. In this tutorial you'll be exposed to most of the Java programming concepts, including Introduction, Object-Oriented Programming (OOP), Strings, Exceptional Handling, Basic Data Type and Advanced topics. You'll also have a Final Project to help you practice along the way.

Believe it or not, Java one of the best programming languages. This Java tutorial series will help you learn Java from fundamentals right from Java applets that allow the language to be utilized like a web programming language. By the time you finish this extensive course, you will become a pro in Java programming irrespective of whether you have any idea about Java right now or not. You'll become adept at using your creativity to make unique, intuitive programs.

Learn to code in Java programming language step-by-step at TechGig, and make your first unique, advanced program in just few days.

Introduction

Java is a popular programming language in use since 1995 when it was first created. Today, Oracle owns Java and the programming language is run on more than 3 billion devices across the world. There are several application areas of Java including the fact that it is extensively used in building web/desktop applications, mobile applications like Android apps, games, servers, etc. The fact that Java is easy to learn and simple to use makes it a popular programming language for Developers. Java also works seamlessly across different platforms such as Android, Raspberry Pi, Mac, Linux, and Windows.

Strings

Strings in Java are used for storing text. It contains a collection of characters surrounded by double quotes. String is an object that constitutes a sequence of characters and the class java.lang.String class is used to create a string object.

Object Oriented Programming

Object-oriented programming (OOP) a software design approach based on objects instead of just functions. Using OOP gives you the benefit of scalability as there are no finite limitations to objects and definitions. Other benefits of OOP include extensibility, reusability, refactoring, efficiency and easy maintenance. Good examples of Object-Oriented programming languages include VB.NET, Python and Java. OOP has the following features: Encapsulation: The benefit of Encapsulation in Java is that it simplifies the program structure and makes it easier to manage everything as the object implementations are clearly defined. Polymorphism: This feature of OOP languages like Java allows for implementation of abstract entities in multiple ways. Inheritance: Implementation fragments are arranged in a hierarchical arrangement or Inheritance.

Exception Handling

Non-adherence to the instructions defined for a program because of any reason results in an Exception. Having said that, there is a difference between and Error and an Exception. While an Error will point to serious problems in a program that applications won\'t be looking to detect whereas an Exception will be those conditions that applications might try and detect. For instance, the Java Exception handling done through the following five keywords: try, catch, throw, throws, and finally.

Advanced

Any Java implementation that goes beyond the Core Java structure falls under Advanced Java. These could be the APIs defined in Java Enterprise Edition, Web Services, Servlet programming, etc. It follows the client & server architecture in web & enterprise application development. Advanced Java fundamentals like Java DataBase Connectivity (JDBC), Java Servlets, Java Servlet Pages (JSP), etc. help in achieving this. There are also advanced frameworks in Java like Struts and JSF which are used to develop secure applications which are especially useful in industries like e-commerce and BFSI.

Basic Data Type

Here are the two data types in Java: Primitive data types: Boolean, byte, char, int, short, long, float and double are all examples of Primitive data types. Non-primitive data types: Arrays, Classes, and Interfaces, are examples of the non-primitive data types.
