After several months of break because of spending time on search and study of javaFX programming language, I decided to use again regular java standard edition (Java SE). (Running back to Java SE on the above photo, taken on April 03, 2009 in Kecioren Gezi Yolu Park, Ankara, Turkey)
JavaFX is very easy to use and very flexible language. However, to run a javaFX jar file, you need to install javaFX-SDK on the computer. Java SE jar files are running on all computers which have only java runtime environment (JRE). Therefore I returned to regular java SE programming for now.
