JDK Document Description callable: Public Interface Callable A task that returns a result and may throw an exception. The implementing person defines a method called call without any parameters. The callable interface is similar to Runnable, and

One is to inherit the thread class, one is to implement the Runable interface, and the other is to implement the callable interface; There are bloggers said only the first 2 ways, I personally humble opinion is three kinds, the main details of the

1. What is the difference between a process and a thread? A process is a standalone (self contained) operating environment that can be viewed as a program or an application. A thread is a task that executes in a process. The Java Runtime environment

Multithreading and concurrency issues are among the questions that interviewers prefer to ask in a Java technology interview. Here, the most important questions are listed from the interview point of view, but you should still have a solid grasp of

1: There are several implementations of multithreading, which are the different?      two kinds.           Inherit the thread class      Implement runnable interface           Extension One: implements the callable interface. This has to be

I. OverviewThe title is very abstract, what is more convenient? Compared to who?Originally, we defined the task to implement the self-runnable or callable interface, but this would necessarily require you to attach the newly defined task to the

I. OverviewSo far, we have been able to declare and make a thread task run up. But there is a problem: the tasks defined now do not have any return values, so join us to let me know when a task runs and tell me a result, the result table name task

Notes [Java7 Concurrent Programming manual] series catalogueBrief introductionOne of the advantages of the execution Framework (Executor framework) is that you can return results when running concurrent tasks. However, the following two classes are

Example 1, using lambda expression to implement runnableWhen I started using Java 8 o'clock, the first thing I did was to replace the anonymous class with a lambda expression, and the implementation of the Runnable interface was the best example of
