How can I create 2 separated Clouds ?

[Azadeh Razmi]

I would like create 2 clouds (a public and a private cloud) and use a
scheduler for pass cloudlets between them , then in second step
develop it by a scheduling task algorithm.
but I have some problem in my project, at first I don't know how to
create two separated Cloud and send cloudlet to them ( I created this
by use two Array lists with different name:like broker_Pr and
broker_Pu and add brokers of Public and Private cloud to them and
datacenter_pr and datacenter_Pu and... is this true?).
