問題描述：

使用Object的clone方法報錯

該行程式碼報錯

node = (Node) curr.clone();

 java.lang.CloneNotSupportedException: com.lbh.xxmanager.basic.alg.Node
	at java.lang.Object.clone(Native Method)
 <hr style=" border:solid; width:100px; height:1px;" color=#000000 size=1">
 

原因分析：

官方註釋，該類沒有繼承Cloneable介面，所以會丟擲CloneNotSupportedException。

解決方案：

繼承Cloneable介面

public class
 
 Node implements Cloneable
