TradingEngineThread-run.java

public class TradingEngineThread extends Thread {
    private final TradingEngine engine;
 
    public TradingEngineThread(long delay, long timeout, Listener listener) throws NamingException {
        super("engine-" + ID++);
        engine = new TradingEngine(delay, timeout, listener);
    }
 
    @Override
    public void run() {
        engine.run();
    }
