Example of producer consumer problem implemented by ruby thread (thread synchronization implemented by queue)

Time:2020-3-31

Ruby thread implements the classic producer consumer problem, and uses the queue class in ruby to implement the thread synchronization problem.

Copy codeThe code is as follows:
require “thread” 
puts “ProAndCon” 

Queue = queue.new – use queue to synchronize threads

producer = Thread.new do 
    10.times do |i| 
Sleep range (I) allows a thread to sleep for a period of time
        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 訙 wait for the output of the consumer thread to complete before shutting down the process
