Using the Java high-speed implementation progress bar

Based on how the progress bar is being asked, here's a simple procedure:

Mostly using JProgressBar (swing built-in Javax.swing.JProgressBar) and SwingWorker (Swing built-in Javax.swing.SwingWorker)

Someone would say, isn't it a thread? Using a thread to share a variable is really possible. Just this way is not too elegant, of course, you can again use the thread encapsulation also line. Just, SwingWorker already helped us to wrap up ~ ~ To use the ready-made things to do or convenient ^_^

First look at the effect:

The following look at the code: very easy, I believe you are greatly sure to understand ~
