How to determine whether the JSlider is currently snapping to tick marks in Java?

At first, we will create a slider and set it to snap to tick marks:

JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, 100, 40);
slider.setMinorTickSpacing(10);
slider.setMajorTickSpacing(20);
slider.setPaintTicks(true);
slider.setPaintLabels(true);
slider.setSnapToTicks(true);

After that, we will check whether the slider is currently snapping to tick marks. The result would be displayed in the TRUE/FALSE boolean

slider.getSnapToTicks()

Display the result in the Console as shown below:

System.out.println("Snapping to tick marks? = "+slider.getSnapToTicks());

The following is an example to determine whether the slider is currently snapping to tick marks:

Example

package my;
import java.awt.Color;
import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JSlider;
import javax.swing.WindowConstants;
public class SwingDemo {
   public static void main(String[] args) {
      JFrame frame = new JFrame("Frame with Slider");
      JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, 100, 40);
      slider.setMinorTickSpacing(10);
      slider.setMajorTickSpacing(20);
      slider.setPaintTicks(true);
      slider.setPaintLabels(true);
      slider.setBackground(Color.CYAN);
      slider.setForeground(Color.black);
      slider.setSnapToTicks(true);
      System.out.println("Snapping to tick marks? = "+slider.getSnapToTicks());
      Font font = new Font("Serif", Font.BOLD, 13);
      slider.setFont(font);
      JPanel panel = new JPanel();
      panel.add(slider);
      frame.add(panel);
      frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
      frame.setSize(600, 300);
      frame.setVisible(true);
   }
}

Output

The console would display whether the Slider is snapping to tick marks or not:
