java克隆的控制

//: CheckCloneable.java
// Checking to see if a handle can be cloned

// Can''t clone this because it doesn''t
// override clone():
class Ordinary {}

// Overrides clone, but doesn''t implement
// Cloneable:
class WrongClone extends Ordinary {
  public Object clone()
      throws CloneNotSupportedException {
    return super.clone(); // Throws exception
  }
}

// Does all the right things for cloning:
class IsCloneable extends Ordinary 
    implements Cloneable {
  public Object clone() 
      throws CloneNotSupportedException {
    return super.clone();
  }
}

// Turn off cloning by throwing the exception:
class NoMore extends IsCloneable {
  public Object clone() 
      throws CloneNotSupportedException {
    throw new C
