well as in c++ we have multiple inheritance, but not in java

becz if it is their then having method of same signature
(means same return type, list of paraments, access 
specifiers) in 2 different classes and both r extended by 
some class AA then while calling method in base class, it 
would break down the jvm that to which classes method to be 
called.
EX:-
class BB
{
 public void a(int x)
 {
  System.out.println("call from BB");
 }
}
class CC
{
 public void a(int x)
 {
  System.out.println("call fro CC");
 }
}
class AA extends BB,CC
{
 a(5);
}

Why? Because it gets confusing.

BCoz of DIAMOND Problem......if A extends B & B extends 
A..in this case b wil override the methods of A class..if c 
Extends A ..in this case  C wil hav Both the properties of 
A,B ....if D extends  A which properties should D 
inherits ..if it B,C propetries Bcoz B are having the same 
methods of A & c is having the same methods of A...there 
occurs the Diamond problem..
