A good answer might be:

ChangeListener


String getName() and int getValue()

Assume that the slider has a name you have set using setName(). The name of the slider is a string that is stored as part of its data. To ask the slider for its name use: 

String getName()

Then, to get the value of the slider use 

int getValue()

The value is an int between the minimum and maximum value of the slider.

QUESTION 11:

Here is part of a program that has two sliders and a text field for each. Fill in the blanks so that when a slider changes its value the value is written it the correct text field. 

JSlider    sliderA;
JTextField textA;
JSlider    sliderB;
JTextField textB;
 
public void stateChanged( ChangeEvent evt )
{
  JSlider source;
  source = (JSlider)evt.getSource();
  if ( source.________().equals("sliderA") )
    textA.setText( source.________ + " " );
  if ( source.________().equals("sliderB") )
    textB.setText( source.________ + " " );
}
