How Can I Display an Indeterminate Progress Bar While Executing a Batch File in Java?

Displaying Indeterminate JProgressBar During Batch File Execution

Introduction:
Users often require visual feedback while executing time-consuming tasks to gauge the progress and avoid confusion. Implementing a progress bar that runs in parallel with the executing process can enhance user experience.

Approach Using SwingWorker:
SwingWorker allows the execution of long-running tasks in the background while the main application remains responsive. It provides methods to update the progress bar and display output to the user.

Code Implementation:
The provided code utilizes a SwingWorker thread to run the batch file in the background. An indeterminate progress bar is displayed, ensuring that the user is aware of the ongoing process.

Key Methods and Properties:

• doInBackground(): Executed in a separate thread, it calls the command and reads the output.
• process(java.util.List messages): Updates the GUI with the output from the command.
• done(): Performs cleanup actions and updates the status once the task is complete.
• setIndeterminate(true): Displays an indeterminate progress bar.

Output Display:
The output from the command is appended to the text area, providing the user with visual feedback on the process.

Benefits:

• Non-blocking GUI execution
• Visual representation of ongoing task
• Enhanced user experience through regular updates
