Using a private variable in a inherited class - Java

Question

Need to have more understanding about the private variables and inheritance. Earlier my understanding was if there is field in a class and when I\'m inheriting the class, th

Answer 1

class A {
  private int a;
  public A(int a) { this.a = a; }
  public int getA() {return a;}
}

class B extends A {
  public B(int b) { super(b); }
  public int getB() {return getA();}
}

int result = new B(10).getA();

result will be 10. Private field a in class A is kind of inherited to B but B can't access it directly. Only by using the public/default/protected accessor methods defined in class A. B is A so it always has all the same fields that are in A and possible some new fields defined in class B.
