1700461834 public class Thing implements Cloneable{
1700461835
1700461836 //定义一个私有变量
1700461837
1700461838 private ArrayList<String>arrayList=new ArrayList<String>();
1700461839
1700461840 @Override

1700461842 public Thing clone(){
1700461843
1700461844 Thing thing=null;
1700461845
1700461846 try{
1700461847
1700461848 thing=(Thing)super.clone();
1700461849
1700461850 }catch(CloneNotSupportedException e){
1700461851
1700461852 e.printStackTrace();
1700461853
1700461854 }
1700461855
1700461856 return thing;
1700461857
1700461858 }
1700461859
1700461860 //设置HashMap的值
1700461861
1700461862 public void setValue(String value){
1700461863
1700461864 this.arrayList.add(value);
1700461865
1700461866 }
1700461867
1700461868 //取得arrayList的值
1700461869
1700461870 public ArrayList<String>getValue(){
1700461871
1700461872 return this.arrayList;
1700461873
1700461874 }
1700461875
1700461876 }
1700461877
1700461878 在Thing类中增加一个私有变量arrayLis,类型为ArrayList,然后通过setValue和getValue分别进行设置和取值,我们来看场景类是如何拷贝的,如代码清单13-11所示。
