The precise meaning of "copy" may depend on the class of the object. * The general intent is that, for any object {@code x}, the expression: x.clone() != x will be true, * and that the expression: x.clone().get

2. x.clone().equals(x) // this is the meaning of ‘copy’ 3. x.clone().getClass() == x.getClass() 4. The object returned by clone method should be independent of the object (which is being cloned). These are not absolute requirements but are general intends of clone method whic...
接下来要重点介绍一下使用java.lang.Serializable来实现对象的深度克隆。 首先,我们编写一个工具类并提供cloneTo()方法。 import java.io.ByteArrayInputStream; import java.io.ByteArrayOutputStream; import java.io.IOException; import java.io.ObjectInputStream; import java.io.ObjectOutputStream; public abstrac...
* @see java.lang.CloneNotSupportedException * @see java.lang.Object#clone() * @since JDK1.0 */ publicinterfaceCloneable { } 不要惊讶,没错,除了一大堆的鸡肠以外,这个接口没有定义任何的方法签名。也就是说,我们要克隆一个对象,但是他又不给我提供一个方法。那该怎么办呢?不怕,我们还有全能的Object...
8. 你必须继承 Cloneable 接口---Cloneable interface is broken in java。otherwise throws java.lang.CloneNotSupportedException. 必须重写 Object 类中的 clone()方法 /* Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general ...

下面是java6 api中对Obejct对象clone方法的注释 Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression: x.clone() != x ...
