Я его правильно написал? public class Rectangle { int top; int left; int width; int height; Rectangle a; public Rectangle (int top) { this.top = top; } public Rectangle (int top, int left) { this.top = top; this.left = left; } public Rectangle (int top, int left, int width) { this.top = top; this.left = left; this.width = width; } public Rectangle (Rectangle a) { a.top = this.top; a.left = this.left; a.width = this.width; a.height = this.height; }
