hexadecimal representation of hash code

Hi All,
when print the object , why it shows the hexadecimal representation of hash code followed by classnamse@ ?How java internally do this ?

Thanks,
Satya

Why? Because that's what the writers of the JVM decided to do.

How does the JVM do it? It's just programming. Why do you need to know that?

Hi,

simply I think standard toString() method is called.

I think that returning className+@+HEX of the hash code was an implementation choice since Java 1.0, a way to return a string without a meaning but at least with a semantic....

You can look at official Java documentation, there's explained how default toString() works.

As Paul has said, Because that's what the writers of the JVM decided to do.

Thanks Paul and Claude for the reply

I know if we override the toString() as per our requirement ....
But I need to know how its actually work behind the back , when the method is not overridden , you can say its just my curiosity ..

Well, it looks like Gaurangkumar Khalasi has explained that. As for your curiosity, that's all very well, but if you also have the goal of being a Java programmer, then in my opinion you're wasting your time with all of these questions you are posting here.

If you want to see how a method such as Object.toString() is implement, then you can lookup the source code - you can find it in the file src.zip which is in your JDK installation directory.
