New rectangle有四个参数:x,y,width和height。实例化一个Rectangle类的方法如下: ``` Rectangle r = new Rectangle(x, y, width, height); ``` x, y,width和height代表矩形的属性。其中,x和y是矩形左上角的坐标;而width和height是矩形的宽度和高度。调用此方法将创建一个矩形,其左上角坐标为(x, y),...
[参考答案]Rectangle2Dr=newRectangle2D.Double(20,30,50,70) 相关知识点: 试题来源: 解析 [解析]该题考查的是Granphics2D几何图形类中的Rectangle2D矩形类。Rectangle2D类描述通过左上角坐标位置(x,y)和矩形尺寸(w,h)定义的矩形。反馈 收藏

这个参数就是让你添加一个矩形所以你首先要实例化一个矩形Rectangle Rtest=new Rectangle(x,y,width,height);x,y表示一个点的坐标,也就是矩形的起始点确定好起始点之后,就是确定矩形的宽度(width),和高度(height)这样就定义了一个矩形参数例如:Rectangle Rtest = new Rectangle(12, 12, 50,...
