public class Rectangle { //在此编写你的代码 int top,left,width,height; public Rectangle(int left,int top,int width,int height) { this.left = left; this.top = top; this.width = width; this.height = height; } public Rectangle(int left,int top) { this.left = left; this.top = top; } public Rectangle(int left,int top,int width) { this.left = left; this.top = top; this.width = width; } public Rectangle(Rectangle rectangle1) { this.left = rectangle1.left; this.top = rectangle1.top; } public static void main(String[] args) { } }
