的Android - 類克隆不工作

Question

public class UserWord extends WordADT { 
    public int WORD_STATUS; 
    public int POINT_OF_WORD; 
    public int COUNT_OF_WRONG_ANSWER; 

    @Override 
    public Object getClone() throws CloneNotSupportedException { 
     return super.clone(); 
    } 
} 

和`

Userword temp = new Userword(); 
Usertword temp2 = temp.getClone();   //this way doesn't work. 

我不能使用getClone（）方法。我收到這個錯誤。我如何克隆一個實例？

java.lang.CloneNotSupportedException：Class UserWord不實現Cloneable。

修正：克隆:(）方法需要實現IClonable inferface

用它來複制任何對象：

public static Object deepClone(Object object) { 
    try { 
     ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(); 
     ObjectOutputStream objectOutputStream = new ObjectOutputStream(byteArrayOutputStream); 
     objectOutputStream.writeObject(object); 
     ByteArrayInputStream bais = new ByteArrayInputStream(byteArrayOutputStream.toByteArray()); 
     ObjectInputStream ois = new ObjectInputStream(bais); 
     return ois.readObject(); 
    } catch (Exception e) { 
     return null; 
    } 
} 

在你的情況使用像波紋管：

Usertword temp2 = (Usertword)deepClone(temp);
