The New to Java Programming Center assists developers who are new to the Java language and platform nderstand the various technologies, and create Java applications.
Java is a high-level language and software-only platform. It runs on more than 50 million personal computers and on billions of devices worldwide. 9 million developers have created Java applications in all major industries.
The two main components of the Java platform are the Java Application Programming Interface (API), which is a library of Java command lines and the Java Virtual Machine (JVM) that interprets Java code into machine language.
The same application can run on multiple platforms
The API and the JVM make the program independent from the underlying hardware

Code a “Hello World” application in Java. Follow these step-by-step instructions to quickly create your first application using a text editor in Windows or with NetBeans Integrated Development Environment (IDE).
Learn Java programming with The Java Tutorials, a comprehensive source for Java language concepts. Object-oriented and Java programming are explained with graphics and code examples.
Pick the right tool. Professionals use NetBeans IDE, an Oracle full-featured Java development software program and JavaFX, a client platform to create and deploy rich Internet applications. Beginners use visual educational tools such as Alice, Greenfoot and BlueJ. The Young Developers page summarizes the tools and learning resources for each software tool.
Java SE lets its users develop and deploy Java applications on desktops and servers, as well as embedded environments. Java SE contains the core of the Java programming language libraries.
The components of Java SE are Java Development Kit (JDK), Java Runtime Environment (JRE) and Java SE application programming interface (API). JDK contains the JRE and the compilers and debuggers necessary for developing applets and applications. JRE provides the libraries, the Java Virtual Machine (JVM) and the components needed to run Java applets and applications. (See graphic below)

JavaFX is an advanced Java user interface platform for enterprise business applications. Developers using Java for both the server and client side can build more robust and reliable applications.
Use JavaFX Scene Builder, a visual layout tool to quickly design user interfaces without coding. Users can drag and drop UI components to a work area, modify their properties, and apply style sheets. This Getting Started tutorial teaches beginners how to create complex user interfaces (e.g. lists, table views, toolbar) and connect to application logic
To create JavaFX applications, developers must install the Java Development Kit (JDK) 8, which includes Java Runtime Environment (JRE), to run the JavaFX tools, samples and applications. Code the "Hello World" application with JavaFX and NetBeans 7.3 by following this text-based tutorial. Continue with the animation of the UI controls with JavaFX Markup Language (FXML) and its application programming interface (API). Explore and choose the UI controls and follow the Getting Started tutorials to create forms, a simple user interface, animations and visual effects. Download and modify the JavaFX sample applications, which are business interface examples that users can experiment with.
Learn tips and tricks with the video below from JavaFX architect Richard Bair.
Java Platform, Enterprise Edition (Java EE) is the industry standard for building web and enterprise applications. Java EE 7 offers new features that enhance HTML5 support, increase developer productivity, and further improves how enterprise demands can be met. Java EE 7 developers will write less boilerplate code, have better support for the latest Web applications and frameworks, and gain access to enhanced scalability and richer, simpler functionality. Enterprises will benefit from new features that enable portable batch processing and improved scalability.
Learn the basic concepts of Java EE platform. Some of the key concepts include Java Persistence API for database integration, EJB for security and transactions, JAX-RS for Restful web-services, servlets and JavaServer Pages. The article Java Technology Terminology has easy to scan definitions. The Java Tutorials provide useful first steps for developers.
Create simple Java EE 7 applications using NetBeans IDE. Java Server Page (JSP), Servlets and Enterprise Java Beans (EJB) are key concepts to build this application. The GlassFish community website offers Java EE Java EE hands-on labs The video below presents Java EE samples deep dives.
From printers and bank machines to e-book readers and cars, Java technology is predominant in today’s embedded systems. It's in 5 billion SIMs and Smart Cards, 3 billion mobile handsets, 80 million TV devices, including every Blu-ray player shipped, and many other embedded solutions. Three technologies are designed for embedded systems: Java SE Embedded for devices with 32MB; Java ME Embedded for devices with 8MB and Java Embedded Suite for devices connecting to a database. Java ME is an environment for applications running on mobile and embedded systems.
In the Java Magazine Internet of Things (IoT) issue, Henrik Stahl discusses IoT for Java developers. Learn how to build smart home applications with the Eclipse SmartHome project, a flexible opensource platform for building mass-market solutions. In his blog, Java architect Hinkmond Wong describes IoT technologies and how to create innovative Java and IoT projects.
Lego Mindstorms EV3 kits are a great way to start programming sensors with Java. Videos, guide and downloads are available here.
