New to Java Programming Center - Downloads 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 Learn about the JVM and the APIs Jump into Java Code a “Hello World” application in Java.

Essentials of the Java Programming Language, Part 1 Training Index If you are new to programming in the Java language, have some experience with other languages, and are familiar with things like displaying text or graphics or performing simple calculations, this tutorial could be for you. It walks through how to use the Java® 2 Platform software to create and run three common types of programs written for the Java platformapplications, applets, and servlets. You will learn how applications, applets, and servlets are similar and different, how to build a basic user interface that handles simple end user input, how to read data from and write data to files and databases, and how to send and receive data over the network. This tutorial is not comprehensive, but instead takes you on a straight and uncomplicated path through the more common programming features available in the Java platform.

Learn Java from the ground up So, you want to program in Java? That's great, and you've come to the right place. The Java 101 series provides a self-guided introduction to Java programming, starting with the basics and covering all the core concepts you need to know to become a productive Java developer. This inaugural article introduces the Java platform and explains the difference between its three editions: Java SE, Java EE, and Java ME. What is Java? You can think of Java as a general-purpose, object-oriented language that looks a lot like C and C++, but which is easier to use and lets you create more robust programs. Let's consider each of these definitions separately: Java is a simple language. Unpacking this definition teaches us a lot about Java. Three editions of Java Sun Microsystems released the Java 1.0 software development kit (JDK) in 1995. Java SE is the foundation platform for Java and is the focus for this series. Overview of the Java platform
Java 101 : Hello World Written by David Reilly Revised May 12, 1999 Previous | Next Editor's Note : When I first wrote this tutorial series, in late 1996, Java was a relatively new language. It had a lot of potential, but a relatively small following by today's standard. -- David Reilly, May 1999 Java quickly became a hot buzzword of the computing industry. Before I begin to cover the basics of Java programming, I should point out that Java is an object-orientated language, and may not be suitable for first time programmers. This tutorial will presume that you have some basic programming knowledge, particularly in C, as it will not be covering such principles as sequence, selection and repetition. Application or Applet? Java software comes in several flavors - the most common being the stand-alone application, and the applet. Applets are commonly used to enhance the interactivity of a web page, and deliver client-side content. Listing 1.0 - myfirstjavaprog.java myfirstprog.java javac myfirstjavaprog.java
