Examples of java.awt.geom.Line2D.intersectsLine()

java.awt.geom.Line2D.intersectsLine()
Tests if the line segment from {@code (x1,y1)} to {@code (x2,y2)} intersects this line segment. @param x1 the X coordinate of the start point of thespecified line segment @param y1 the Y coordinate of the start point of thespecified line segment @param x2 the X coordinate of the end point of thespecified line segment @param y2 the Y coordinate of the end point of thespecified line segment @return if this line segment and the specified line segmentintersect each other; false otherwise. @since 1.2
