Getting started with Java programming

As is the case with many worthwhile endeavors, Java programming requires that you have some tools to begin. Fortunately, all of the software tools that youwill need to get started programming in Java are available for free downloading.

In addition to a computer with web access, you will need:

  • The Java Development Kit (JDK) and Java Runtime Engine (JRE)
  • The Java API documentation
  • A suitable text editor

The JDK and the JRE

The JDK, the JRE, and the API documentation are all freely available from Oracle. As of January 2016, you will find links to the documentation on the webpage titled Java Platform Standard Edition 8 Documentation . (The links given in this module may change as new versions of Java are released, but newer versions shouldn't be too difficult to locate with a websearch.)

Download

The JDK and the included JRE can be downloaded from (External Link) That page provides several download options. Beginners should download the Java Platform (JDK) for the latest released version. (The JRE is included in the JDK package, so you don't need to download both.)

Install

You will also probably need to follow the installation instructions for your computer. Pay particular attention to the instructions for setting the path and classpath environment variables. This is where many students stumble. Another usefuldocument on the path and classpath is available at (External Link)

The Java API documentation

The Java Platform, Standard Edition 8 API Specification is available here . You should be able to find the documentation for later versions with a web search.

Also see my Java OOP documentation module for instructions on how to use the documentation.

A suitable text editor

The module titled Jb0110: Java OOP: Programming Fundamentals, Getting Started explains how to use a text editor to create Java program code. Just about any text editor willdo as long as you can ensure that the file name extension is .java. Something as simple as Windows Notepad or Windows WordPad would probably be best for your first few simple programs.

Soon, however, you will probably want to upgrade to an editor that uses different colors to identify the different parts of your program. My favoritecolor-coded editor is the free version of JCreator . (The free version seems to have disappeared from their web page so you may have trouble finding it.)

Another free editor is DrJava . An advantage of this editor is that it can be run from a USB drive with no installation required. Anotherpossibility, although I have never had occasion to use it, is jGRASP . Numerous other Java color-coded editors, including BlueJ are available for free downloading on the web.
