Disclaimer ;-‐)

Not all tools I’m talking about today are free or open source.

I assume all a7endees are familiar with (i) refactorings in Eclipse, (ii) generaXng ge7ers/se7er, hashCode, equals++ with Eclipse, and (iii) you daily use keyboard shortcuts.

No refactorings and (almost) no shortcuts today!

If you don’t know your keyboard shortcuts...

No Mouse! #dcr13

way."
