Java Tutorial : Java Object Class(clone method)

Book.java

public class Book implements Cloneable
{
    private String name;
    private String isbnNumber;

    public Book(String name, String isbnNumber)
    {
        super();
        this.name = name;
        this.isbnNumber = isbnNumber;
    }

    public String getName()
    {
        return name;
    }

    public void setName(String name)
    {
        this.name = name;
    }

    public String getIsbnNumber()
    {
        return isbnNumber;
    }

    public void setIsbnNumber(String isbnNumber)
    {
        this.isbnNumber = isbnNumber;
    }

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

}

ObjectClassTest.java

public class ObjectClassTest
{

    public static void main(String[] args)
            throws CloneNotSupportedException
    {
        Book childrenStoryBookObj = new Book("Children Story", "2000");
        System.out.println("Original book Object ...");
        System.out.println("Name        = "
                + childrenStoryBookObj.getName());
        
        System.out.println("ISBN Number = "
                + childrenStoryBookObj.getIsbnNumber());

        Book clonedChildrenStoryBookObj = (Book) childrenStoryBookObj
                .clone();

        System.out.println("----------------------------");
        System.out.println("Cloned book Object ...");
        System.out.println("Name        = "
                + clonedChildrenStoryBookObj.getName());
        System.out.println("ISBN Number = "
                + clonedChildrenStoryBookObj.getIsbnNumber());

    }

}

Output

Original book Object ...
Name        = Children Story
ISBN Number = 2000
----------------------------
Cloned book Object ...
Name        = Children Story
ISBN Number = 2000
