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

java.awt.geom.Point2D.distance()
Returns 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 distance between the two sets of specifiedcoordinates. @since 1.2
