Creating an application in Netbeans

Goal of this tutorial Project 1 requires you to develop and test a graphical user interface (GUI) Netbeans allows you to quickly create a GUI using Java – Programs can be run on any operating system Today’s lecture will show you how to do this

Goal of this tutorial Not required to use Netbeans, but: – Sample code will only be provided in Java – You need to make sure that your program can run on both Windows and Mac OSX – The TA may not be able to help you if you chose to develop in another language

Setup Download Netbeans – Download Java JRE/JDK 8 v25 – Note: You must install at least the JRE 8v25 to make sure that you can run other student’s programs who have developed them in Java, even if you decide to develop your program in a different language

Develop a desktop application Past years have required you to host your application on a website – This is not required this year Recommend you create a standard Java Application, not a Java Applet

Creating a new Project File > New Project Select Java Application (in the Java folder) Name it whatever you would like Uncheck Create Main Class

Creating the GUI Right-click on your new project and click New Select Other Select the Swing Gui Forms folder and create a JDialog Form – You can ignore the warning about using the default package

Source and Design Panes Select your new JDialog Form You should see three buttons/tabs labeled Source, Design, and History. – Source shows the source code for your form – Design shows the GUI designer – History shows your change history Source and Design are the important ones

Using the Design Pane Working with the Swing designer: gui.html gui.html

Building an Executable JAR Open your project’s Properties and select Packaging Check all three checkboxes and hit OK Run > Build Project Open the project directory The executable.jar is in the dist folder – There may be a lib folder as well, if your project needs any additional libraries Zip the.jar file and the lib folder (if it exists) People can unzip the file and run your program by double-clicking on the jar file

Hosting on the CISE Servers Install WinSCP (other FTP programs are fine) Connect to storm.cise.ufl.edu (other servers are fine) Place the zip file in your public_html directory – Create the directory if it doesn’t exist – Set the folder permissions to rwxr-xr-x (i.e. 0755) – Permissions can be set in WinSCP in the folder’s properties Set your zip file’s permissions to rw-r--r– (i.e. 0644) Applying for an account: Download at /

Advice for Project 1 Building a translation program to help people ask for directions – Translation will be done using Google’s APIs Make sure your application supports other character sets (English + Chinese characters) Make sure you test your input to ensure that other character sets can be entered

Google Translate API Class TA will provide more information – Demo project contains two important classes: TranslateService.java and Language.java TranslateService.java – Call the method translate to get a translation Language.java – Defines constants for all of the languages supported by Google Translate
