why c++ support multiple inheritance but not java code example

Example: multiple inheritance in c++

#include<iostream> 
using namespace std; 

class A 
{ 
public: 
A() { cout << "A's constructor called" << endl; } 
}; 

class B 
{ 
public: 
B() { cout << "B's constructor called" << endl; } 
}; 

class C: public B, public A // Note the order 
{ 
public: 
C() { cout << "C's constructor called" << endl; } 
}; 

int main() 
{ 
	C c; 
	return 0; 
}
