停止紅寶石 - jRuby - 線程在一定時間後

Question

我試圖用jRuby創建一個簡單的多線程程序。它需要基於指定的時間量開始和停止線程，例如，運行五秒鐘然後停止。我對這類東西相當陌生，所以它可能很基本，但我無法讓它工作。

相關的代碼如下所示：

require 'java' 
require 'timeout' 
require './lib/t1.rb' 
require './lib/t2.rb' 

class Threads 
    [...] 

    def manage_threads 
    thread2 = T2.new 
    # Wait for 5 seconds before the thread starts running.. 
    thread2.run(wait_time = 5) 

    Timeout::timeout(10) do 
     thread1 = T1.new {} 
    end 
    end 

class T1 < Thread 

    def initialize 
    while super.status != "sleep" 
     puts "Thread 1"  
     sleep(1) 
    end 
    end 
end 

class T2 
    include java.lang.Runnable 

    def run wait_time 
    thread = Thread.new do 
     sleep(wait_time) 
     loop do 
     puts "Thread 2" 
     sleep(1) 
     end 
    end 
    end 

    def stop_thread(after_run_time) 
    sleep(after_run_time) 
    end 
end 

我已經嘗試了，如果事情，例如：

# Used timeout 
Timeout::timeout(10) do 
    thread1 = T1.new {} 
end 

# This kinda works, except that it terminates the program and therefore isn't the behavior 
# I want. 

有沒有人對如何1.啓動一個線程的建議，運行一段時間。 2.開始一個新線程，並行運行兩個線程。 2.停止線程1，但繼續運行線程2.任何提示/建議，將不勝感激。

我想我解決了它。

這奏效了：

def run wait_time 
    thread = Thread.new do 
    sleep(wait_time) 
    second_counter = 0 
    loop do 
     puts "Thread 2" 
     second_counter += 1 
     if second_counter == 15 
     sleep 
     end 
     sleep(1) 
    end 
    end 
end
