Question

Using Java how do i do create a JSlider that does the following?

(Sliders and a label) The user has 100 skill points to spend across 4 different passive skills. The user will see a label with “100” on it originally.

Whenever he/she slides a slider to increase the skill points in that skill, the points are taken from the 100 points (or however many are remaining.)  

When the user decreases the skill points in a particular area, they are returned to the “points left to spend” pool, and this is reflected in the label as well. The remaining points will always be displayed in this label.

If the player runs out of points to spend, he/she should not be able to increase the points in any skill area until points are returned to the pool, and are available to be spent

The four (4) skill areas are as follows:

Intelligence, Dexterity, Strength, and Wisdom
