Document Summary

Processing adds some magic: we have to write that ourselves now. The way we think about problemsthe transition from python java. Java is bracketed language: python is whitespace delimited. Python has weak-typing: in java, variables can only be one type, the(cid:455) (cid:272)a(cid:374)"t (cid:272)ha(cid:374)ge. This means we have a pipeline/toolchain we need to use.

The jvm is installed when you install the java runtime environment. We want more tools, so we need java development kit. Dr. java (open source) - windows and old os x.
