Java has a singly rooted hierarchy - all objects in Java extend Object,
its just that the compilers are reuiried to allow a shorthand:
class foo {}
for
class foo extends java.lang.Object {}
Its impossible to declare a class in Java that isn't an Object.
I believe this is also true in C#, but certainly not in C++ or Objective-C.
