所有的程序都是从MAIN方法开始一步一步往下运行，你看程序下面都是输出了。你这样看看 public static class TestRectangle{ public static void main (String args[]){ Rectangle r1=new Rectangle(5.6,12.5);Rectangle r2=new Rectangle(2,3);} class Rectangle{ double width;double height;Rectang...

另外，构造成员函数一般都应用public类型来说明，这样才能在程序任意的位置创建类的实例－－对象。下面是一个Rectangle类的构造成员函数，它带有两个参数，分别表示矩形的长和宽：public Rectangle(int w,int h){ width=w;height=h;area=getArea(w,h);} 除了...
