Examples of java.awt.geom.Point2D.distanceSq()

java.awt.geom.Point2D.distanceSq()
Returns the square of the distance between two points. @param x1 the X coordinate of the first specified point @param y1 the Y coordinate of the first specified point @param x2 the X coordinate of the second specified point @param y2 the Y coordinate of the second specified point @return the square of the distance between the twosets of specified coordinates. @since 1.2
