Answer:

source = (JSlider)evt.getSource() ;

if ( !source.getValueIsAdjusting() )
{
  if ( source.getName()().equals("sliderA") )
    textA.setText( source.getValue() + " " );
  if ( source.getName()().equals("sliderB") )
    textB.setText( source.getValue() + " " );
}

For fun, modify the previous program to see the result of this patch.

Other Useful Slider Methods

Here are a few other sometimes useful methods from class JSlider. For additional discussion go to How to Use Sliders in Sun's on-line Java Tutorial.

int getMaximum()   
    // Returns the maximum value supported by the slider. 
int getMinimum()   
    // Returns the minimum value supported by the slider. 

These two methods are useful when the application methods must scale their output proportional to the possible range of values.

void setInverted(boolean b) 
    //Set to true to reverse the order of values on the slider 

This method with a horizontal slider makes the values ascend going from right to left (the revers of the usual order).
