Hi,
i am trying to add a Label on top of JSlider Knob
to display some values in that Label as the Slider moves forward or back side the values displayed in label must change and Label has to move along with Knob of the JSlider.
i am capturing the values from a text field which can be change by user.
pls try to reply.
thanks

hello,
I would use CardLayout for changing the labels. I have made the experience, that this works better (and is less risky) than repainting the label yourself.
1.) create a CardLayout that contains every label as a component (see the Swing Tutorial on CardLayout). you can change the content of the CardLayout dynamically, or create a new one later on.
2.) attach the appropriate listener to the JSlider. this listener will call the show-method on the CardLayout to switch to the specific label. as you can switch to the next and to the previous component of a CardLayout (thus, they are ordered), this listener won't even have to bother whith the name of the cards. At least, that's what I'm thinking right now, without having implemented anything.
hope this did help you a bit

to place the labels directly over the knob, I'd add some empty border of a width that depends on their index in the list of labels.
