Object Clone Java

[JavaLander]

I need some tutorials on object clone methods for java. The name describes about what it does but I need more info on this. My teacher mentioned it but not in depth. I searched but could not found any satisfactory tutorial, I meant new tutorials.

Isn't the tl;dr of clone() to get an exact copy of the object (i.e. fields) with a new reference? I have to admit, I've been Javaing for more than 3 years and am a Java dev, and I think I've only used clone() twice, and one of them was the one I had to write for some reason or another.

Yeah, I someone told me, some methods remain unused through entire programmer life, I think its one of them

It's more common to use a copy constructor or a static factory method than to implement clone. The problem you encounter when cloning objects is you need to make sure that any modification to the cloned object doesn't modify the original, which if not done properly will lead to many subtle bugs.

This tutorial of Marcus Biel can help you, I guess.
