在一段时间后停止Ruby - jRuby - 线程

我正在尝试使用jRuby创建一个简单的多线程程序。它需要根据指定的时间量启动和停止线程,例如跑了五秒钟然后停下来。我对这类东西很陌生,所以它可能非常基本,但我无法让它工作。

相关代码如下所示:

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

我已经尝试了一些事情,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. 

有没有人建议如何1.启动一个线程,运行一段时间。 2.启动一个新线程,并行运行两个线程。 2.停止线程1,但继续运行线程2.任何提示/建议将不胜感激。

我想我解决了。

这就是诀窍:

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
