为什么选择SwingWorker?为什么不只是Thread或Runnable? [英] Why SwingWorker? Why not just Thread or Runnable?

问题描述

使用 SwingWorker 代替 Thread 或 Runnable 有什么优势?

What are the advantages of using SwingWorker instead of Thread or Runnable?

推荐答案

线程和Runnable是Java 1.0的一部分；他们和当时一样出色.

Thread and Runnable were part of Java 1.0; they're as good as they were back then.

从那时起，新的并发类将提炼出所有有关多线程的知识(感谢您，Doug Lea和其他人).编写多线程代码非常困难.包括SwingWorker在内的新的并发类都试图使其变得更容易.

The new concurrency classes distill all that's been learned about multi-threading since then (thank you, Doug Lea and others). Writing multi-threaded code is terribly difficult. The new concurrency classes, including SwingWorker, try to make that easier.

首先要注意强类型的泛型.有内置的机制可以发布和处理最终结果和中间结果.

Start by noting the generics for strong typing. There's a mechanism built in to publish and process both final and intermediate results.

可以使用Thread和Runnable来模仿它们，但是SwingWorker已经为您完成了.

It'd be possible to mimic these with Thread and Runnable, but SwingWorker has done it for you.
