What are the characteristics of deep copying in Java?

Here are some characteristics of deep copy in Java:

1. Full Copy: Deep copy creates a new object and copies all the attribute values of the original object to the new object, including both primitive and reference type properties.
2. Independence: After a deep copy, the new object and the original object are completely independent, modifying the new object will not affect the original object.
3. Recursive copying: Deep copying recursively copies all reference type properties of an object, ensuring that all properties of the copied object are independent.
4. Object diagram copying: deep copying can replicate the entire object diagram, including the relationships and references between objects.
5. Object cloning: One common way to implement deep copy in Java is by using the object cloning method, which involves implementing the Cloneable interface and overriding the clone() method.

It is important to note that to achieve deep copying, reference type properties also need to be deep copied, otherwise only the reference will be copied instead of the actual object.
