Swing Examples - Creating Slider with Custom Label

Following example showcases how to use a slider with custom labels in a Java Swing application.

We are using the following APIs.

• JSlider(orientation, min, max, value) − To create a slider while orientation set the vertical orientation.

• JSlider.getValue() − To get the current value of slider.

• JSlider.setLabelTable() − To set the labels.

• JSlider.setPaintLabels(true) − To show the labels.
