Java programming inevitably to contact multithreading, inevitably to contact synchronization, asynchronous. This series will take a closer look at the JDK’s thread synchronization library.
Computer program = data + algorithm.
All the fundamental reason for concurrent programming is to ensure the correctness of data and efficiency of threads.
The Java concurrency library is divided into four large sections, as shown below
Executors and futures are designed to keep threads efficient
Locks and data structures are used to maintain data consistency.
When you do concurrent Java programming, the order of thinking is,
Either lock your own data. Or use the data structure provided to ensure data security
Use Executor for better scheduling when scheduling threads.
