java的clone对象

[hui94781674]

怎么实现对ShapeManager的深复制哈。。

public class ShapeManager implements Cloneable{
     private ArrayList<Shape> shapes = new ArrayList<Shape>();

	public ArrayList<Shape> getShapes() {
		return shapes;
	}

	public void setShapes(ArrayList<Shape> shapes) {
		this.shapes = shapes;
	}
	
	public void setShape(Shape shape){
		shapes.add(shape);
	}

	@Override
	protected ShapeManager clone() throws CloneNotSupportedException {
		ShapeManager copy = (ShapeManager)super.clone(); 
		return copy;
	}
}

thinking in java 中查一下也就知道了哈，不是太常用。

protected ShapeManager clone() throws CloneNotSupportedException {
        ShapeManager copy = (ShapeManager)super.clone(); 
		ArrayList<Shape> temp=new ArrayList<Shape>(shapes);
		copy.setShapes(temp);
        return copy;
    }
