Program Plan Intro

a.

Sliders:

• The component that is used for adjusting the numbers graphically for the range of values that are being specified is called as sliders.
• The sliders are being displayed in range that one end contains the minimum value and the other end contains the maximum value.
• Tick mark is being displayed along with the labels to indicate the values.
• There are two types of tick marks and they are:
  • Major tick mark
  • Minor tick mark
• The spacing and appearance of the tick mark can be controlled using the method present in the “JSlider” class.
• The spacing present between the minor and the major tick marks can be adjusted using the methods namely:
  • setMajorTickSpacing
  • setMinorTickSpacing
    • The above methods hold the integer value as the argument.

Explanation of Solution

b.

Establishing the spacing of minor tick marks:

• For establishing the spacing of minor tick marks the “setMinorTickSpacing” method is used.
• This method holds an integer argument which specifies the intervals of the tick marks.

Example:

Consider an example of the “setMino...

Explanation of Solution

c.

Cause tick marks to be displayed:

• By default, the tick marks are not displayed and setting their spacing doesn’t cause tick mark to be displayed.
• The “setPaintTicks” method is called for displaying the tick marks that accepts a “Boolean” argument.
  • If the argument passed is “true” then the tick marks are displayed.
  • If the argument passed is “false” then the tick marks are not displayed...

Explanation of Solution

d.

Cause labels to be displayed:

• By default, the labels are not displayed.
• The “setPaintLabels” method is called for displaying the labels that accepts a “Boolean” argument.
  • If the argument passed is “true” then the tick marks are displayed.
  • If the argument passed is “false” then the tick marks are not displayed...
