在一段时间后停止Ruby-jRuby-thread

我试图用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，例如运行五秒钟，然后停止。我对这类东西很陌生，所以它可能很基本，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

有没有人对如何使用1有什么建议。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。如有任何提示/建议，将不胜感激

我想我解决了

这就成功了：

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

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
