I have no idea how to do this 😬😬 I tried but it never works. "The program you are given takes length and width of a rectangle as input. Complete the method to take t
Find the total area covered by two rectilinear rectangles in a 2D plane. Each rectangle is defined by its bottom left corner and top right corner as shown in the figure. Assume that the total area is never beyond the maximum possible value of int. 解题思路: 几何题目。 代码如下: 1 2 3 ...
publicRectangle(intw,inth){ super(); width = w; height = h; } /* * Define a public method `getArea` which can calculate the area of the * rectangle and return. */ // write your code here publicintgetArea(){ returnwidth * height; ...
Rectangle(double w, double h) { width=w; height=h; } public double getPerimeter() { return 2*( width+height);} public double getArea() { return width*height; } public String toString() { return "width="+width+",height="+height+ ",perimeter="+getPerimeter()+",area="+getArea();...
