How Can I Display an Indeterminate Progress Bar During Batch File Execution in Java?

Visualizing Indeterminate Progress while Executing Batch Files

Many developers face challenges in providing visual feedback to users during the execution of batch files, which can take some time. This can leave users unsure whether the program has become unresponsive. To address this issue, this article explores techniques for displaying an indeterminate progress bar while the batch file is running and closing it upon completion.

One approach employs a SwingWorker with a ProcessBuilder running in the background. This allows for both output display and a progress bar simultaneously. The code example provided illustrates how a user can start the process, view the output, and stop the process on demand.

As an alternative, developers could consider using a separate library specifically designed for handling background tasks in a Swing application. The Java Concurrency package or third-party libraries like TaskChain and RxJava can provide additional features and flexibility in managing long-running tasks.
