### 面向对象软件体系结构 ###

例：

class Spot{
        private int x,y;
        Spot(int u, int v){
            setX(u);
            setY(v);
        }
        void setX(int x1){
            x=x1;
        }
        void setY(int y1){
            y=y1;
        }
        int getX(){
            return x;
        }
        int getY(){
            return y;
        }
    }
    class Trans{
        void move(Spot p, int h, int k){
            p.setX(p.getX()+h);
            p.setY(p.getY()+k);
        }
    }
    class Text{
        public static void main(String args[]){
            Spot s = new Spot(2,3);
            System.out.println("s点的坐标:" + s.getX() + "," + s.getY());
            Trans ts = new Trans();
            ts.move(s,4,5);
            System.out.println("s点的坐标:" + s.getX() + "," + s.getY());
        }
    }

运行结果：  
![Center][]

作：

class Rectangle{
        private int x,y,a,b;  //长方形的两个点
        Rectangle(int u, int v,int c,int d){
            setX(u);
            setY(v);
            setA(c);
            setB(d);
        }
        void setX(int x1){
            x=x1;
        }
        void setY(int y1){
            y=y1;
        }
        void setA(int x2){
            a=x2;
        }
        void setB(int y2){
            b=y2;
        }
        int getX(){
            return x;
        }
        int getY(){
            return y;
        }
        int getA(){
            return a;
        }
        int getB(){
            return b;
        }
        int getW()
        {
        	return Math.abs(a-x);
        }
        int getH()
        {
        	return Math.abs(b-y);
        }
        int getArea()
        {
        	return Math.abs(a-x)*Math.abs(b-y);
        }
    }

class Trans{
        void move(Rectangle p, int h, int i,int j,int k){
            p.setX(p.getX()+h);
            p.setY(p.getY()+i);
            p.setA(p.getA()+j);
            p.setB(p.getB()+k);
        }
    }

class Text{
        public static void main(String args[]){
            Rectangle lyy_s = new Rectangle(1,1,3,4);
            System.out.println("1点的坐标:" + lyy_s.getX() + "," + lyy_s.getY());
            System.out.println("2点的坐标:" + lyy_s.getA() + "," + lyy_s.getB());
            System.out.println("面积：" + lyy_s.getArea());
            Trans ts = new Trans();
            ts.move(lyy_s,1,2,3,4);
            System.out.println("1点的坐标:" + lyy_s.getX() + "," + lyy_s.getY());
            System.out.println("2点的坐标:" + lyy_s.getA() + "," + lyy_s.getB());
            System.out.println("面积：" + lyy_s.getArea());
        }
    }

运行结果：
