83.JAVA programming Ideas-about Java performanceThe Java language has a particular emphasis on accuracy, but reliable behavior is at the expense of performance. This feature is reflected in aspects such as automatic garbage collection, rigorous run-time checks, full bytecode checking, and conservative run-time synchron

Next, we'll take a look at the second topic of Web Programming on Java: URL processing. The URL (uniform Resource Locator) Chinese name is a Uniform Resource locator, sometimes also known as the Web address. Represents a resource on the Internet, such as a Web page or an FTP address. This time we'll see that Java is like processing URLs. URLs can be divided into

operation can get the opportunity to execute. The use of read and write locks can greatly simplify the programming difficulty, in the read operation to obtain read locks, because read locks can be read by multiple threads to obtain, so improve the degree of parallelism, write operations to obtain write locks.
