Java does not support multiple inheritance.Why?

If anybody ask u why java does not support multiple
inveritance then answer is:"Whenever we create an instance
of a child class and we extend more then one class like
C++, then if these two classes contain same variable then
which will print if we try to print the variable."

Example:
class a
{
int i = 10;
}
class b
{
int i = 10;
}

class c extends a,b
{
public static void main(String[] args)
{
c c1 = new c();
System.out.printn(c1.i);//Here an ambiguous situation
will occur
}
}
