Java thread pool FutureTask implementation principle explanation, javafuturetaskPreface The thread pool can execute multiple tasks concurrently. In some cases, we may want to track the execution results of the task, or even if the task is not

There are three methods to create a Java thread. 1. inherit Thread class creation Thread 2. Implement the Runnable interface to create a thread 3. Use Callable and Future to create a thread The first and second methods are commonplace. I will not

Connect to the abovelegacy Issues in the previous articleFor Java Multi-threading understanding. I used to confine myself to implementing the Runnable interface or inheriting the thread class, then overriding the run () method, and finally the start
