If you extend more than one class JVM does n't understand
for which object it has to create object first.so ambiguios
occurs.That's y java does n't support multiple inheritance.


We can implement multiple inheritance by using interfaces.

Interface A
{
public void X();
}
class B implements A
{

public void X()
{
s.o.p("this is function x");
}
public void Y()
{
s.o.p("this is function y");
}

}

class C extends B
{
public void X(){...}
public void j(){...}

P S V M()
{

A a =new C();
a.X();
}
}

if a class wants to extend 1 or more classes define those
function definitions in one interface and in another class
provide bodies by implementing those interface.

if the class can extend the class which is implementing that
interface then u can access all functions present in that
interface.


here my interface A

i provide bodies in class B by implementing interface A

class C extend that class B

and class c is able to access all the methods present in the
interface by creating the reference of an interface with the
object of class C

(remember 1 thing to the reference of interface we can
assign object of class only if it is implementing that
interface)

here class c extends class B and again class B implements

interface A

so i can write

A a= new C();
