The Java EE platform uses a simplified programming model. XML deployment descriptors are optional. Instead, a developer can simply enter the information as anannotationdirectly into a Java source file, and the Java EE server will configure the component at deployment and runtime. These annotations ...

This is a great time to be Java developer. According to the latest statistics provided at the JavaOne 2008 conference, there are over 6 billion Java-enabled devices deployed worldwide. These devices can range from large-scale enterprise class servers down to a tiny smart card that fits in yo...
So it's harder to do the kind of microperformance optimization with Java code that one can do in C. At the same time, the fact that the compilation is done at execution time means that the optimizer has far more information to work with than the C compiler does. It knows what classes...

Java 多线程 (Part2: Java线程 Lock锁) Java 锁的分类图 1. 乐观锁 vs 悲观锁 悲观锁:一定会出现多线程场景,先加锁,Synchronized 和 Lock 都是悲观锁(适合 write多) 乐观锁:不一定出现多线程场景,先不加锁,如果数据未更新,单线程write;如果数据更新;多线程write(适合read多),CAS算法就是乐观锁, Atomic...
wait()方法调用后,线程不会自动苏醒,需要别的线程调用同一对象的notify()或者notifyAll()方法。sleep()方法执行完成后,线程会自动苏醒,或者可以使用wait(long timeout)超时后线程会⾃动苏醒。 为什么我们调⽤ start() ⽅法时会执⾏ run() ⽅法,为什么我们不能直接调⽤run() ⽅法?
