You can read a file like that or a StringInputStream) with CSV.  See

You can also use Pattern split then parseFloat.

It should not be considered an error when the user starts something
already started or stops something already stopped. This applies
to browsers, services, editors... It is inexcusable to 
punish the user by requiring some elaborate sequence to atone,
e.g. open the task editor, find and kill some processes.
