They are the child classes of the parent class called java.lang.Object , other than that , there is no visible relationship.

Based on the information you supplied. No, there is no relationship. In java, both inherit from the java.lang.Object. But from OO perspective, there is no relationship.

Class can be related in the following ways:

Aggregation - This is a has-a relationship where Class A has at least 1 field whose type is of classB Inheritance - This is an is-a relationship where a class B is a specialization of another class A. In this kind of relationship, the classB inherits all the behaviours of the class A.

There is no relation between those classes.

The only relationship that I can see is that they both implicitly inherit from Object.
