When we want to copy an object in Java, there are two possibilities that we need to consider,a shallow copy and a deep copy. For the shallow copy approach, we only copy field values, therefore the copy might be dependant on the original object. In the deep copy approach, we make sure...
We can make a deep copy of an object by using the Cloneable() interface and overriding the clone() method. Copy constructors are an easier and more flexible way of performing a deep copy. We can also use Serialization but we need to remember that its computation is expensive than other ...

A class implements the Cloneable interface to indicate to the Object.clone() method that it is legal for that method to make a field-for-field copy of instances of that class. 倘若我们在没有实现Cloneable接口的情况下重载clone()方法,则会在调用时抛出CloneNotSupportedException异常(属于checkedExceptio...
