17. Comparison: Java applets – Statistics app
Advantages
Disadvantages
Virtual repository
(Java applets)
Minimal amount of text (translation easy)
Self-explaining use
Java does not operate on smartphones / tablets
Since January 2013: Security warnings occur
Statistics App
(HTML5, CSS 3, JavaScript)
Platform-independence; responsive web design; enhanced media mix via QR codes
Didactical limitations for smartphones due to small display size
Programming difficult (competing web browsers)
