since java doesn,t support multiple inheritance,
to overcome the disadvntage of multiple inheritance
interfaces are came.

multiple inheritance means,many sub classes can share 
the properties of base class

interfaces are also providing the same feature
but,the class which is implemented the interface
that should give the definition for all the methods present
in the interface.
so,one interface can be implemented by no of classes
by this,the ambiguities are rectified in interfaces

sorry Padmaja,

Multiple inheritance is way of accessing one sub(child) class from multiple base(parent) classes.

in java is  possible through interfaces but not through classes.
