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 booleanslider.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:Examplepackage 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) ...
