Are there any classes that don’t inherit Object as SuperClass or maybe have become Obsolete/deprecated?
According to Java Object superclass,
java.lang.Objectdoes not extendObject.Other than that, all classes, i.e.
implicitly extend Object class, if they don’t extend any other super-class.
Interfaces, on the other hand, do not extend Object, as Interface, by definition, can not extend Class.
Also, Interfaces can not contain callable methods, nor can objects be instantiated from them. When interfaces are finally implemented, the implementing class will necessarily extend Object (and, no,
Objectdoesn’t implement or extend any other entity/class/interface).
