Example of a Ruby thread implementing a producer consumer problem (Queuing queue Implementation thread synchronization) _ruby topic

The ruby thread implements the classic producer consumer problem, using the queue class in Ruby to implement thread synchronization issues.

Copy Code code as follows:

Require "thread"
Puts "Proandcon"

Queue = Queue.new #用队列Queue实现线程同步

Producer = Thread.new Do
10.times do |i|
Sleep rand (i) # Keep threads asleep for a while
Queue << I
Puts "#{i} produced"
End
End

Consumer = thread.new Do
10.times do |i|
Value = Queue.pop
Sleep rand (I/2)
Puts "consumed #{value}"
End
End

Consumer.join #等待consumer线程的输出完成再关闭此进程
