What value does the standard implementation of the toString method in Java return if it is not overridden?

If the toString() method in Java is not overridden, its default implementation from the Object class returns a string in the format:

ClassName@hashcode_in_hex

For example, for an object of class MyClass, it might be:

MyClass@1a2b3c4d

where 1a2b3c4d is the hash code of the object obtained by the hashCode() method, converted into a hexadecimal string.
