This article mainly introduces "what are the benefits of java multithreading". In daily operation, I believe many people have doubts about the benefits of java multithreading. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "what are the benefits of java multithreading?" Next, please follow the editor to study!

Improve the utilization of CPU, make better use of system resources, use Monitor classes to synchronize all or part of the code of static / instantiated methods, and use different synchronization classes to create your own synchronization mechanism.

Multithreading refers to the technology of concurrent execution of multiple threads from software or hardware. Computers with multithreading capabilities are able to execute more than one thread at a time to improve overall processing performance because of hardware support. Multithreading means that a program contains multiple execution streams, that is, multiple threads of different systems can be run simultaneously in a program to perform different tasks, allowing a single program to create multiple threads of parallel execution to complete their respective tasks.

The benefits of multithreading improve the utilization of CPU. In multithreaded programs, when a thread has to wait, CPU can run other threads instead of waiting, which greatly improves the efficiency of the program.

First, the advantage of multi-thread

Applications that adopt multithreading technology can make better use of system resources. The main advantage is that it makes full use of the free time slice of CPU and responds to the requirements of users with as little time as possible, which greatly improves the overall running efficiency of the process and enhances the flexibility of the application. Because all threads in the same process share the same memory, there is no need for a special data transfer mechanism, and there is no need to establish a shared storage area or shared files. This makes it easier to solve the problems of coordinated operation and operation between different tasks, data interaction, resource allocation and so on.

Thread synchronization, in multithreaded applications, consider data synchronization between different threads and prevent deadlocks. A deadlock between threads occurs when two or more threads wait for each other to release resources at the same time. In order to prevent the occurrence of deadlock, thread safety needs to be achieved through synchronization. There are three ways to accomplish thread synchronization in Visual Basic. The synchronized keyword is available in Java.

Second, code domain synchronization

Use the Monitor class to synchronize all or part of the code snippet of a static / instantiated method.

Third, manual synchronization

You can use different synchronization classes to create your own synchronization mechanisms. This synchronization method requires you to manually synchronize different domains and methods, which can also be used to synchronize between processes and release deadlocks caused by waiting for shared resources.

IV. Context synchronization

Use SynchronizationAttribute to create simple, automatic synchronization for ContextBoundObject objects. This synchronization method is only used for instantiated method and domain synchronization. All objects in the same context domain share the same lock.

At this point, the study on "what are the benefits of java multithreading" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
