I am assuming you have create some JPanel or JFrame where you add this slider so,

final JSlider jSlider1 = new JSlider();
    jSlider1.setValue(0);
    jSlider1.setMaximum(100);
    jSlider1.setBounds(0, 50, 300, 50);
    final Timer increaseValue = new Timer(50, new ActionListener() {// 50 ms interval in each increase.
        public void actionPerformed(ActionEvent e) {
            if (jSlider1.getMaximum() != jSlider1.getValue()) {
                jSlider1.setValue(jSlider1.getValue() + 1);
            } else {
                ((Timer) e.getSource()).stop();
            }
        }
    });
    panel.add(jSlider1);
    JButton moveSlider = new JButton("Start");
    moveSlider.setBounds(10, 106, 55, 30);
    moveSlider.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent event) {
            increaseValue.start();
        }
    });
    panel.add(moveSlider);

but where is your code? I mean I understood you made Instance variable for Timer but I still don't know where your getting problem ,create new question or add code to this question so that we can take a look at it! – Yogesh Feb 17 '14 at 09:31
final Timer increaseValue = new Timer(sliderUnitVal, new ActionListener() {// 50 ms interval in each increase. public void actionPerformed(ActionEvent e) { if (jSlider1.getValue() != 85) { jSlider1.setValue(jSlider1.getValue()+1); lblShow.setText(Integer.toString(jSlider1.getValue())) ; } else { ((Timer)e.getSource()).stop(); } } }); – user3317730 Feb 17 '14 at 09:33
I put the veriable sliderUnitVal, for time. But then method is not workin properly. But I put the exact value, then it works properly – user3317730 Feb 17 '14 at 09:40
Make sure sliderUnitVal is initialized. check if it has certain value assigned to it before it is being refered in Timer, and still problem persists then create new Question cause this is comment section and we need to avoid discussions in it! – Yogesh Feb 17 '14 at 09:47
OK. Iwill do it next time. Please help me for this time. I initialized it. And also value is pass to the method. but it is not working for given value. – user3317730 Feb 17 '14 at 09:56
