There are some reasons because of them java soft remove
multiple inheritance -
Suppose there are 4 classes A,B,C,D.

Class A - contains some abstract methods, final methods,
private methods.
Class B - contains some complete methods, some final
methods.
Class C - contains some static methods, complete methods.
Class D - contains some final methods, static final methods
and so on..

And programmer create a subclass for extending these 4
classes like this -

public class ChildClass extends A,B,C,D
{
---------
--------- // lots of confusions for programmer here.
}

The subclass programmer may be confused. Because he need to
concentrate on what are availables in supper classes. Thats
why java soft people remove multiple inhiritance.

But in case of Interface --

public interface childInterface extends Interface_A,
Interface_B, Interface_C, Interface_D
{
--------
-------- // No confusion here. Because Interface contains
only abstract methods. And abstract method doesn't have
body.
}
