在 java 中通过多线程显示进度

Question

I am trying to call a function initialStep() of MainApp class from ProcessStatements class. When the function initialStep() is called, i want to show progress bar to the user till the initialStep() function completes the execution.

How can i do this using Java Swing? Please someone help me out. Thanks in advance:)

Answer 1

I recommend using a SwingWorker for the task.

The main issue is that the Swing stuff needs to be done on the EDT (Event Dispatch Thread). The SwingWorker takes care of all that. The progress bar can be a simple JProgressBar in a window or whatever is desired.

Happy coding.
