util.concurrent 是一个 Java 语言的并发开发包，示例代码：

public class Executor
{
    private static Logger logger = Logger.getLogger(Executor.class);
    private static PooledExecutor executor = new PooledExecutor(5);
   
    static {
        executor.setMinimumPoolSize(2);
        executor.setMaximumPoolSize(10);
        executor.setKeepAliveTime(1000 * 60 * 10);
    }
   
    public static void execute(Runnable runnable) {
        try {
            executor.execute(runnable);
        }
        catch (Exception e) {
            logger.error("Exception while running task: " + e, e);
        }
    }
