跨平台：同时支持Linux32/64、OSX64、Win64等平台； * 高性能：同时具备C/C++和Java并发库的优点，性能爆棚； * 类丰富：实现JDK丰富的类库，从此摆脱C++贫类库的困境； * 易开发：先java开发，再使用`CxxJDK`进行翻译，So easy! #### 示例 `java:` ``` public static void main(String[] args) { class Worker implements Runnable { @Override public void run() { try { Thread.sleep(1000); } catch (InterruptedException e) { e.printStackTrace(); } System.out.println(String.format("thread %d finished", this.hashCode())); } } ThreadPoolExecutor executor = new ThreadPoolExecutor(100, 200, 10, TimeUnit.SECONDS, new LinkedBlockingQueue()); executor.allowCoreThreadTimeOut(true); for (int i = 0; i < 200; i++) { executor.execute(new Worker()); } executor.shutdown(); } ``` `c++:` ``` int main(int argc, const char **argv) { ESystem::init(argc, argv); //cxxjdk初始化! class Worker : public ERunnable { public: virtual void run() { try { EThread::sleep(1000); } catch (EInterruptedException& e) { e.printStackTrace(); } ESystem::out->println(EString::formatOf("thread %d finished", this->hashCode()).c_str()); } }; EThreadPoolExecutor* executor = new EThreadPoolExecutor(100, 200, 10, ETimeUnit::SECONDS, new ELinkedBlockingQueue()); executor->allowCoreThreadTimeOut(true); for (int i = 0; i < 200; i++) { executor->execute(new Worker()); } executor->shutdown(); executor->awaitTermination(); delete executor; //对象资源释放! } ``` 以上示例是不是够吸引人？ 更多示例： [testefc.cpp](test/testefc.cpp)
