     * 假设有一个银行网点，有多个窗口用于处理客户的业务。
     * 现在需要编写一个程序模拟该网点的业务处理过程，要求如下： 网点有 N 个窗口，用一个线程池管理这些窗口的线程。
     * 每个窗口可以同时处理多个客户的业务，但同时最多只能服务 K 个客户。
     * 客户可以在任意窗口进行业务办理，但需要等待窗口空闲后才能进行服务。
     * 当一个客户到达银行网点后，随机选择一个窗口进行排队等待服务，直到业务处理完成。
     * 在业务处理过程中，客户不能在多个窗口进行业务办理。
     * 请根据以上要求，编写一个 Java 程序实现银行网点的业务处理过程。
     *
     * 要求： 1、java代码实现 2、构造3组测试用例，可以执行通过 3、注释、日志齐全
