What are some examples of cloning in Java?

In Java, cloning is a way to create a copy of an object. You can use the clone() method from the Object class. Would you like to see a code example?

Yes, please provide a code example.

Sure! Here's a simple example:

class Person implements Cloneable {
    String name;
    int age;

    Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    @Override
    protected Object clone() throws CloneNotSupportedException {
        return super.clone();
    }
}

public class Main {
    public static void main(String[] args) throws CloneNotSupportedException {
        Person person1 = new Person("Alice", 30);
        Person person2 = (Person) person1.clone();
        System.out.println(person2.name + " is " + person2.age + " years old.");
    }
}

This code demonstrates how to clone a Person object.

What are the limitations of cloning in Java?

Cloning in Java has some limitations, such as:

1. Shallow copy vs. deep copy: The default clone() method creates a shallow copy, which may not be suitable for objects containing references to mutable objects.
2. CloneNotSupportedException: If a class does not implement the Cloneable interface, calling clone() will throw this exception.
