Multiple inheritance can be a serious mess and has been a point of contention in the C++ world, therefore Java has removed the notion of multiple inheritance.
However, you can implement multiple interfaces.

Do you mean multiple inheritance?
If so, preventing multiple inheritance avoids many of the associated problems such as where D extends B and C both of which extend A. If you call a method on D which is implemented in B and C, which implementation do you choose?
Multi level inheritance (e.g. C extends B extends A) is allowed.
 
Don't get me started about those stupid light bulbs.
