The role of cloneable interface
The function of the cloneable interface is to identify a class that can be cloned. The cloneable interface is a marker interface used to indicate that classes that implement this interface can perform cloning operations. The cloneable interface does not contain any methods, it is just an empty interface. However, its presence is essential to enable cloning functionality. When a class implements the cloneable interface, it means that the class can be cloned. This means that you can use the clone() method in the Object class to create a copy of the class.

Deep copy and shallow copy methods of Java Cloneable interfaceCloneable interface source code Cloneable interface: A class that implements this interface - it can be inferred that the clone() method of java.lang.Object can be legally called - to implement class instances: property-to-property copying. If a class does not implement the Cloneable interface, a CloneNotSupportedException exception will be thrown when the clone() method is called. Generally, subclasses that implement the Cloneable interface should override the clone() method with public access (although the clone method in the java.Object class is prote
How to use Java deep copy, shallow copy and Cloneable interface1. Introduction to Cloneable interface Cloneable is a tagged interface (empty interface). They have no internal methods and properties. To implement Cloneable to indicate that the object can be cloned, you can use the Object.clone() method. If clone() is called on a class object that does not implement Cloneable, a CloneNotSupportedException exception will be thrown. It can be understood that the Cloneable interface plays a marking function. Custom types require users to mark which classes can be cloned. This mark is to implement the Cloneable interface. After implementing the Cloneable interface, it indicates that the class created
