Loop unrolling: the Server VM features loop unrolling, a standard compiler optimization that enables faster loop execution. Loop unrolling increases the loop body size while simultaneously decreasing the number of iterations. Loop unrolling also increases the effectiveness of other optimizations. Feedback-...

For example, here is a class that uses a semaphore to control access to apool of items: 通过semaphore的构造方法可以确定所有权限的最大个数,使用Semaphore的acquire()方法(无参数)可以获得一个permit,只要线程获取的次数<创建的个数就无需阻塞,如果超过构造时最大的个数,就进行阻塞,而semaphore的release()...
The Trouble with Variables It is tempting to create a single template and set a variable for the destination of the link, rather than go to the trouble of setting up a parameterized template and calling it two different ways. The idea is to set the variable to a default value (say, the...
