| Star2D | | public class Star2D implements Shape(Code) | | This class provides a star shape. A star is defined by two radii and a
number of branches. Each branch spans between the two radii. The inner
radius is the distance between the center of the star and the origin of the
branches. The outer radius is the distance between the center of the star
and the tips of the branches.

Parameters:
y - the location of the star center
Parameters:
innerRadius - the distance between the center of the star and theorigin of the branches
Parameters:
outerRadius - the distance between the center of the star and thetip of the branches
Parameters:
branchesCount - the number of branches in this star; must be >= 3
throws:
IllegalArgumentException - if branchesCount is < 3 orif innerRadius is >= outerRadius |
