Difference between "clone" and creating a new object

Question

Hi experts,
What on earth is the difference between:
1)creating a new object by using the "clone()" method and
2) just creating a new object?
Let me be a bit more specific:
if there's a class called "Book" and suppose we've already created an object called "japaneseBook", any difference between "Book spanishBook = new Book();" and "Book spanishbook = japaneseBook.clone()"?
Thank you.

The purpose is very obvious. At anytime in the running application, when Objects have been changed, and you desire to make another one of the same kind, you can't use new. You would use clone. The newer Object would have the same values in the variables. Now i got a question.. an important issue.
public class XYZ{   
  public static int t = 10;
} // default constructor is present by default.
                 //In another portion i have the following..
private XYZ x = new XYZ( );  // private Object!!
     // Now what about this one????
public XYZ x1 = x.clone( );  // public !!, well
What impact of this code can be there to break the rules of good OOP design??? Is it that a clone Object would have the same access of itself (not of its variables) or different one?????????
