chvili jsem si s tim hral a staci nastavit to snapToTicks(), ten listener je
zbytecny...
pokud by se to z nejakeho duvodu nelibilo, tak prekryt metodu setValue:
class MySlider extends JSlider {
@Override
public void setValue(int n) {
if (n % 5 == 0) {
super.setValue(n);
}
}

JFrame f = new JFrame("Test");
final JSlider slider = new JSlider(0, 100, 50);
final JLabel valueLabel = new JLabel("");
slider.getModel().addChangeListener(new ChangeListener() {
public void stateChanged(ChangeEvent e) {
final int val = slider.getValue();
if (val % 5 == 0) {
valueLabel.setText(String.valueOf(val));
}
}
});
slider.setMinorTickSpacing(5);
slider.setMajorTickSpacing(20);
slider.setPaintTicks(true);
slider.setSnapToTicks(true); //!
valueLabel.setText(String.valueOf(slider.getValue()));
final Container contentPane = f.getContentPane();
contentPane.setLayout(new GridLayout());
contentPane.add(valueLabel);
contentPane.add(slider);
f.setSize(200, 150);
f.setLocationRelativeTo(null);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setVisible(true);
