Accessing inherited class variables in java

Question

If you inherit from an activity where certain member variables were declared, how do you access these member variables in the subclass executing the inheritance?

Answer 1

class A {
    protected int a = 3;
}

class B extends A {
    protected int b = 2;

    void doIt() {
        System.out.println("super.a:" + super.a);
        System.out.println("this.b: " + this.b);
    }
}

Answer 2

public or protected member names can be accessed via this.memberName from any constructor or non-static method or initializer.

private or package level members (accessed from a subclass in a different package) cannot be accessed directly and will need to be accessed via an unprivileged interface such as a public getter.
