Talking about Java multithreading

Multithreading in Java involves the following 4 points:

1. Java threads can be created in two ways: inheriting the tread class and implementing the Rannable interface;
2. In the use of multithreading, you can manually instantiate a number of threads or use the thread pool Executorservice;
3. Multithreading if you want to share data, you can use synchronous synchronized to perform operations in the Run method;
4. Reasonable use of multi-threaded synchronization data to prevent deadlock problems.
