Java-related software (JRE)

During the course you will create Java programs in the form of console applications (which consist of single java files). It offers practical information on how you download and install any necessary software. To be able to run Java programs requires a JRE (Java Runtime Environment) , ie, a software environment that can “interpret” and run Java code. To develop Java applications will also need a “compiler” to compile the code you wrote. Both components come with what is called the Java JDK (Java Development Kit), often also called SDK (Software Development Kit). Such a “package” with Java SE (Standard Edition), can be downloaded for free from Oracle but – ATTENTION – it is NOT that you will use. Since JDK is not equipped graphical development tool, they must refer to the command prompt, Notepad, which requires insight and habit. Therefore, we have chosen an alternative tool with graphical programming environment – Eclipse – which is also free. Although this requires a JRE installed, so you who do not already have Java software (JRE electricity. JDK) for Java, (see your installed programs in the Control Panel “Add / Remove Programs”), must begin by downloading and installing a separate Java from Oracle. Among the options on the download page, select the “JRE” – Download button, found under the heading “Java Platform, Standard Edition” – ie, the release that has the following name: Java SE 8u91 / 8u92 . On the following page, which has versions for multiple operating systems, select the course the option that suits your computing environment.

Eclipse IDE for Java Developers

To avoid (?) To work with Command Prompt and Notepad, we have chosen a more “competent” IDE (Integrated Development Environment), ie, a graphical development tool called Eclipse (link below provides you with version 4.4.2). This tool has worked well in previous courses, is free and available for multiple platforms (Windows, Mac OS, Linux). The following helps you download, install and get started with the program.

• Installation
  1. Please note that the above-described JRE must be installed  before the eclipse fetched! 2. Go to: http://www.eclipse.org/downloads/ 3. Click: “Eclipse IDE for Java Developers” in order to choose the correct version for your operating system (Windows / Mac / Linux). Select the download link and check carefully where you put the compressed “eclipse-java-March 2 …” – folder. (There are a variety of “Java packages” for different applications, but the proposed tool above will be enough for this the course’s needs.) After the download, the development tool is extracted to the location where you want it. It is best to unpack the program in your root directory , for example, C: Program Files, instead of placing it on the desk (which in some cases has caused problems.) For help with the installation, you get the following page, under the section Installing Eclipse: http://wiki.eclipse.org/FAQ_Where_do_I_get_and_install_Eclipse% 3F
  
  
  
• Getting started
  in the “Welcome” (which opens when the eclipse starts) you will find a first very good supervision during Tutorials : “Create a Hello World application”. It shows the main hand grips to create your first (?) Java program – go through it! Very interesting information is found under Overview -> “Java Development”, that is part of the Eclipse Help Center. Look especially at what is written in “Java Development User Guide” in the Contents view.
  Please explore further the Eclipse “Eclipse Newcomers FAQ” : http://www.eclipse.org/home/newcomers.php !
• Troubleshooting / Help Tip
  Changing computing environment with different JRE versions sometimes give problems, so you may need to change the JRE (-sökväg) for your project. Solution? Select from the menu bar Help : “Tips and Tricks -> Eclipse Java Development Tools -> OK -> Miscellaneous -> Select Execution Environment for Java project”. Follow the instructions to “pinpoint” your installed Java.
  As you become more warm clothes can be found from the Help menu many other useful tips for your programming or on the Eclipse tool.

Adobe Reader

Most of the course material is distributed in the form of PDF files. In order to take advantage of them, you must have Adobe Reader installed.

Are you Mac users?

In order to make the theoretical stage test, you must remotely (Remote Desktop Connection) use a virtual classroom where the test tool is installed. A remote-desktop client for Mac can be found at this link: http://www.microsoft.com/en-gb/download/details.aspx?id=18140 .

PowerPoint Viewer

A few parts of the course material is also available in the form of PowerPoint presentations (with some animation). If you want to see them you need MS Office PowerPoint or (free) software PowerPoint viewer installed.
