4. 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!

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

6. No
Mouse!
