Notes:
-
The JSlider is used to create the slider. By using JSlider a user can select a value from a specific range.
- JSlider(): creates a slider with the initial value of 50 and range of 0 to 100.
- JSlider(int orientation): creates a slider with the specified orientation set by either JSlider.HORIZONTAL or JSlider.VERTICAL with the range 0 to 100 and initial value 50.
- JSlider(int min, int max): creates a horizontal slider using the given min and max.
- JSlider(int min, int max, int value): creates a horizontal slider using the given min, max and value.
- JSlider(int orientation, int min, int max, int value): creates a slider using the given orientation, min, max and value.
