How to run .class file made in eclipse (package declared .class file)

cd to right path.

In my case ~/workspace/masa/bin (eclipse workspace)

and

java <package name>.<class file name> (without extension)

e.g

java masa.Rand

(/home/masa/workspace/masa/bin/masa/Rand.class is target file)

or use java -cp . masa/Rand (at ~/workspace/masa/bin )

#package #namespace
