State whether the following statememnt is true or false:
At //1 a1.i is valid.

Select 1 correct option.

The answer is True. How?? Its compiling fine.

The private keyword means that no one can access that member except the methods of that class. So, a private modifier can only curb the member access from external classes and not to the members within including the inner classes and other methods.
For example, If you create another class B with a private member j in it and instantiate it in class A, you will not be able to access j from class A where as you will be able to access i from within A from all the methods.
