Java CloneNotSupportedException用法及代碼示例

拋出CloneNotSupportedException表示調用了Object類中的clone方法來克隆一個對象，但該對象的類沒有實現Cloneable接口。

等級製度：

那些重寫克隆方法的應用程序也可以拋出此類異常，以指示對象不能或不應該被克隆。

用法:

public class CloneNotSupportedException extends Exception

CloneNotSupportedException 的示例：

Java


// Java program to demonstrate CloneNotSupportedException
class TeamPlayer {
    private String name;
    public TeamPlayer(String name)
    {
        super();
        this.name = name;
    }
    @Override public String toString()
    {
        return "TeamPlayer[Name= " + name + "]";
    }
    @Override
    protected Object clone()
        throws CloneNotSupportedException
    {
        return super.clone();
    }
}
public class CloneNotSupportedExceptionDemo {
    public static void main(String[] args)
    {
        // creating instance of class TeamPlayer
        TeamPlayer t1 = new TeamPlayer("Piyush");
        System.out.println(t1);
        // using try catch block
        try {
             
             // CloneNotSupportedException will be thrown
             // because TeamPlayer class not implemented
             // Cloneable interface.
              
            TeamPlayer t2 = (TeamPlayer)t1.clone();
            System.out.println(t2);
        }
        catch (CloneNotSupportedException a) {
            a.printStackTrace();
        }
    }
}
