Java OS进程队列

我正在使用本机ProcessBuilder类来创建一个可变大小的进程对象列表。目前，我简单地浏览了每个Process实例上调用start方法的列表。然而，我想通过将我的运行进程的数量限制为自定义值（例如处理器的数量）来更好地控制应用程序的这个方面。哪些数据结构，现有库或模型最适合此任务？Java OS进程队列

Example 

List<Process> processList = new ArrayList<Process>(); 
ProcessBuilder pb1 = new ProcessBuilder("myCommand", "myArg1", "myArg2"); 
ProcessBuilder pb2 = new ProcessBuilder("myCommand", "myArg1", "myArg2"); 
processList.add(pb1); 
processList.add(pb2) 

for(Process p : processList) 
(
    // more control is needed here 
    p.start(); 
}

使用ThreadPoolExecutor。一个简单的例子：

public class PBTest { 

static List<Runnable> list = new ArrayList<Runnable>(); 

public static void main(String args[]) { 
    ProcessBuilder pb1 = new ProcessBuilder("foo.exe"); 
    ProcessBuilder pb2 = new ProcessBuilder("foo.exe"); 
    ProcessBuilder pb3 = new ProcessBuilder("foo.exe"); 
    addPB(pb1); 
    addPB(pb2); 
    addPB(pb3); 

    ExecutorService ex = Executors.newFixedThreadPool(1); 
    for (Runnable r : list) { 
     System.out.println("calling execute"); 
     ex.execute(r); 
    } 

    ex.shutdown(); 
} 

static void addPB(final ProcessBuilder pb) { 
    list.add(new Runnable() { 
     public void run() { 
      try { 
       pb.start(); 
      } catch (IOException ioe) { 
       ioe.printStackTrace(); 
      } 
     } 
    }); 
}

}
