简单的线程控制

DataThread.java控制其他线程是否运行：

public class DataThread extends Thread
{
    public void run()
    {
        SendThread send = null;
        Thread SendThread = new Thread(send);
        while (true)
        {
            try
            {
                if ("0158".equals(WmsFormatter.toParamTime(new Date()).substring(0, 4)))
                {
                    if (SendThread.isAlive())
                    {
                        send.close();
                    }
                }

                if (!hostSendThread.isAlive())
                    {
                        send = new SendThread();
                        SendThread = new Thread(send);
                        SendThread.start();
                    }
                Thread.sleep(50000);
            }catch (Exception e)
            {
             try {
                    e.printStackTrace();
                        continue;
                   } catch (Exception e1) {
                         continue;
                   }
            }
        }
    }

    public static void main(String[] args)
    {
        new DataThread().start();
    }

SendThread.java
public class SendThread implements Runnable
{
    private boolean flag = true;

    public void close()
    {
        flag = false;
    }

    public void run()
    {
        while (flag == true)
        {
            
        }
    }
}
