import javax.swing.JTextField;
import javax.swing.SwingUtilities;
import javax.swing.border.EmptyBorder;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;
import javax.swing.event.DocumentEvent;
import javax.swing.event.DocumentListener;


public class BlueSliderBeanFrame extends JFrame implements DocumentListener       {

/**

private static final long serialVersionUID = 1L;
/**

private JPanel contentPane;
private JTextField textField;


JSlider slider = new JSlider();
private JTextField textField_1;
JSlider slider_2 = new JSlider();


/**

public static void main(String[] args) {
    EventQueue.invokeLater(new Runnable() {
        public void run() {
            try {
                BlueSliderBeanFrame frame = new BlueSliderBeanFrame();
                frame.setVisible(true);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });
}

/**

    textField = new JTextField();
    textField.getDocument().putProperty("owner", textField);
    textField.getDocument().addDocumentListener(this);
    textField.setBounds(53, 37, 125, 50);
    contentPane.add(textField);
    textField.setColumns(10);

    textField_1 = new JTextField();
    textField_1.getDocument().putProperty("owner", textField_1);
    textField_1.getDocument().addDocumentListener(this);
    textField_1.setColumns(10);
    textField_1.setBounds(53, 126, 125, 50);
    contentPane.add(textField_1);


    slider.setValue(0);
    slider.addChangeListener(new ChangeListener() {
        public void stateChanged(ChangeEvent arg0) {
                textField.setText(String.valueOf(slider.getValue()));
                }
        });
    slider.setMaximum(999);
    slider.setBounds(188, 37, 200, 50);
    contentPane.add(slider);

    slider_2.addChangeListener(new ChangeListener() {
    public void stateChanged(ChangeEvent e) {
        textField.setText(String.valueOf(slider_2.getValue()));
        }
    });

    slider_2.setMaximum(999);
    slider_2.setBounds(188, 126, 200, 50);
    contentPane.add(slider_2);




}



public void updateSlider( int i ) {

    Runnable doHighlight = new Runnable() {

    @Override
    public void run() {
     // your highlight code
     int val = 0;

Just need to update your code little bit,

Updated Code :

 slider_2.addChangeListener(new ChangeListener() {
    public void stateChanged(ChangeEvent e) {
         /* 
         here you did wrong...
         textField.setText(String.valueOf(slider_2.getValue()));
         */
        textField_1.setText(String.valueOf(slider_2.getValue()));
        }
    });
