Every class in java must have only one root class (i.e
Object class) directly or indirectly.
If Class C extends Class A and Class B(this approach is not
supported in java ),here Class A will one root Object
class,similarly Class B will have Another root class.i.e
Here Class C is having two root classes....For this reason
java not supporting Multiple inheritance with respective
Objacts.
Every objects need some common functionalities which are
available in Object class.
