Ambiguity in interfaces

Question

interface A
{
  int a = 10;
}

interface B
{
  int a = 10;
}

class Access implements A, B
{
}

class Demo
{
  public static void main(String args[])
  {
    Access ac = new Access();
    System.out.println(ac.a);   // line #1
  }
}

Line #1 causes ambiguity. How do I remove it? Is it not possible to have same variable name of different interfaces?

Answer 1

You will have to reference the two variables as A.a and B.a respectively;

Answer 2

System.out.println( ((A)ac).a);   

or
System.out.println( ((B)ac).a); 

If you have variables which are conflicting then you need to use resolution to access value of particular interface.
