Re: [Jython-users] Classes and threads

[Frank C. <fc...@pu...>]

Thanks for the reply. So I wrote a class using the Java Threading class 
as:

import java.lang.Thread as JThread

class myclass( JThread ):
   def initialize( self, id ):
     self.id = id
   def run( self ):
     for i in range(1000):
       print slef.id, i

a = myclass()
a.initialize(1)
b=myclass()
b.initialize(2)

a.start()
b.start()

When I run this everything works as expected. a and b run concurrently 
and step on each other's output.

Using this design, how can I use mutex and synchronize functions?
