The purpose of using namespaces is to localize the names of identifiers to avoid naming conflicts. In C + +, variables, functions, and classes exist in large numbers. Without namespaces, the names of these variables, functions, and classes will all

Discussion and application of Java threads Longs One, why to study and use the thread In general, the programs that the computer is executing are called processes (process), the processes have different address spaces, and are different programs

Starting with Java 5, the Java.util.concurrent.locks package contains some of the lock implementations, so you don't have to implement your own locks. But you still need to know how to use these locks. A simple lock. Let's start with a

about blocking the main thread error usage for join Thread.Join () acts as a blocking main thread, that is, when the child thread is not returned, the main thread waits for it to return and then continues execution. Join cannot be used with start

Thinking logic of computer programs (66) and thinking 66 We mentioned two problems of multi-thread shared memory in the previous section. One is the race condition and the other is the memory visibility. we mentioned that one solution to these two

Swift Programming Language -- Instance Methods and Type Methods) The method is a function associated with certain types. You can define instance methods for classes, structs, and enumerations. instance methods encapsulate specific tasks and

Locks in Java Locks, like synchronized synchronous blocks, are a thread synchronization mechanism, but more complex than the synchronized synchronization blocks in Java. Because locks (and other more advanced thread synchronization mechanisms) are

To date, the Rtti forms we have known include: (1) classic styling, such as "(Shape)", which uses RTTI to ensure the correctness of the styling and creates a classcastexception violation after encountering a failed shape. The (2) Represents the
