Core Java Tutorials
Hollis Abdelkarim
Our core Java programming tutorial is designed for students and working professionals. Java is an object-oriented, class-based, concurrent, secured and general-purpose computer-programming language. It is a widely used robust technology.
Java was developed by Sun Microsystems (which is now the subsidiary of Oracle) in the year 1995. 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.
Standalone applications are also known as desktop applications or window-based applications. These are traditional software that we need to install on every machine. Examples of standalone application are Media player, antivirus, etc. AWT and Swing are used in Java for creating standalone applications.
An application that runs on the server side and creates a dynamic page is called a web application. Currently, Servlet, JSP, Struts, Spring, Hibernate, JSF, etc. technologies are used for creating web applications in Java.
An application that is distributed in nature, such as banking applications, etc. is called an enterprise application. It has advantages like high-level security, load balancing, and clustering. In Java, EJB is used for creating enterprise applications.
It is a Java programming platform. It includes Java programming APIs such as java.lang, java.io, java.net, java.util, java.sql, java.math etc. It includes core topics like OOPs, String, Regex, Exception, Inner classes, Multithreading, I/O Stream, Networking, AWT, Swing, Reflection, Collection, etc.
It is an enterprise platform that is mainly used to develop web and enterprise applications. It is built on top of the Java SE platform. It includes topics like Servlet, JSP, Web Services, EJB, JPA, etc.
Welcome to Core Java Tutorial. I have written a lot on Core Java and Java EE frameworks. There was no index post for Core Java tutorial and I used to get emails asking to make one so that any beginner can follow them and learn core java programming. Finally, I got time and here I am listing all the core java tutorial related posts that I think will help you in learning core java in no time. This list is updated till Java-10 and soon it will be updated with the latest changes in Java-11 and beyond.
While we believe that this content benefits our community, we have not yet thoroughly reviewed it. If you have any suggestions for improvements, please let us know by clicking the report an issue button at the bottom of the tutorial.

Happy learning!
In 1991 James Gosling and his friends formed a team called Green Team to further work on this project. The original idea was to develop this programming language for digital devices such as television, set-top box, remote etc. Later this idea was dropped and Java is developed for internet programming.
Hello Chaitanya,
I am pretty sure that over a period of time you will upload more concepts and tutorials for different technologies, but at the same time I would suggest or better request you to add a frame where you or anybody can post different questions related to particular concept and a person can try writing a code for it. Like a list of programs or something similar to exercises given in Kathy Serra , which on solving can make person better understand the concepts and have hands on programming experience.
Sun Microsystems developed the Java programming language in May 1995. It was introduced with the help of Java Development Kit (JDK), which contains a Java Runtime Environment (JRE). The JRE contains a Java Virtual Machine (JVM) and software tools such as Java application program interfaces (APIs) that help the development of Java applications. The first version of JDK was 1.0 and the latest release of Java Standard Edition is Java SE 10. Developers have defined various configurations of Java in order to fulfill the requirements of multiple platforms such as Java EE for Enterprise Applications and Java ME for Mobile Applications.
Java is an object-oriented, cross-platform, powerful and robust programming language with support for security and strong memory management. It also provides support for a multithreading feature with which you can write code that can perform several functions simultaneously. Most developers choose Java as a programming language while creating an application or working on any project because of its amazing features. Java is widely used for developing web applications, software, and web portals as well.
The Java source code is saved with .java extension. It is necessary to compile a Java program before its execution. Like other programming languages such as C++ and C, Java also allows you to store data in variables.
First and most importantly, someone who wishes to be a programmer needs to learn programming logic. If you have to be able to think in algorithmic terms, to break down a problem in a series of ordered, unambiguous instructions that even something as dumb as a computer can carry out. The great news is that programming logic is a 100% transferable piece of knowledge. You learn it once, and then you have it for life. Logic is always the same for all programming languages.
On top of logic, you have to learn the language itself. For instance: its syntax, its reserved words, and how to perform common tasks such as text manipulation, basic arithmetic operations, and calculations with date and time.
Codecademy is probably one of the best places to learn Java online. It is an education company, which focuses on enhancing the online learning experience of students. It provides free courses of Java programming language for both beginners and experienced programmers.
