Display tick marks in a JSlider with Java

To display tick marks in a JSlider, you need to use the setPaintTicks() method and set it to TRUE −

JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, 100, 75);
slider.setPaintTicks(true);

The following is an example to display tick marks in a slider in Java −

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, 75);
      slider.setMinorTickSpacing(5);
      slider.setMajorTickSpacing(20);
      slider.setPaintTicks(true);
      slider.setPaintLabels(true);
      slider.setBackground(Color.yellow);
      slider.setForeground(Color.red);
      Font font = new Font("Serif", Font.BOLD, 18);
      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);
   }
}
