The progress bar offers the ability to display the actual value of the bar as a percentage. This example demonstrates how to enable this display. 
Note: The percentage display should not be enabled when the maximum is not known (e802 Creating a JProgressBar Component with an Unknown Maximum). 

    // Create a horizontal progress bar
    int minimum = 0;
    int maximum = 100;
    JProgressBar progress = new JProgressBar(minimum, maximum);
    
    // Overlay a string showing the percentage done
    progress.setStringPainted(true);
