Explanation of Solution

Sliders:

• A slider is a component that permits the user to graphically adjust a number within a range of values.
• Using “JSlider” class, user can create a slider.
• It shows an image of a “slider knob” that can be dragged along a track.
  • It can be oriented horizontally or vertically.
• The range of slider is represented by a numeric value.
  • The minimum range’s value is present at the one end of slider.
  • The maximum range’s value is present at the other end of slider.
• Slider contains a numeric value, and as the user moves the knob along the track, the numeric value is adjusted correspondingly.
• The constructor format for “JSlider” class is given below:

  JSlider(int orientationType, int minimumValue, int maximumValue, int initialValue)

  • From the above format, the “orientationType” may be one of the constants that is “JSlider.HORIZONTAL” or “JSlider.VERTICAL”.
  • The “minimumValue” indicates the minimum value of the slider’s range.
  • The “maximumValue” indicates the maximum value of the slider’s range.
  • The “initialValue” indicates the slider initial value.
• User can assign the major and minor tick mark spacing using the method called “setMajorTickSpacing” and “setMinorTickSpacing”.
• Display the tick marks on a slider by using the method “setPaintTicks”...
