我有写一个kochcurve的code，但是的时候什么都显示不出来，可以帮忙改一下吗? package EC; import gpdraw.DrawingTool; import gpdraw.SketchPad; public class KochCurve { private DrawingTool pen; private SketchPad paper; public KochCurve(){ paper = new SketchPad(500,500); pen = new DrawingTool(paper); } public void draw(int level, int length) { if (level < 1) pen.forward(length); else { draw(level - 1, length / 3); pen.turnLeft(60); draw(level - 1, length / 3); pen.turnRight(120); draw(level - 1, length / 3); pen.turnLeft(60); draw(level - 1, length / 3); } } } ======== package EC; public class Driver { public static void main(String[] args) { KochCurve kc = new KochCurve(); kc.draw(6,300); } }
