Variables declaired as private in one class can be accessed into another class without using inheritance i.e extend and obj...?

Question

Encapsulation concept. Can a Data hidden in one class be accessed into another class..?

Answer 1

private variables cannot be accessed from outside the class directly, that's what private does.

To access the private value indirectly from outside the class use a getter/accessor.
(A public method that returns the private value for you)

Example/

class Person{

private int age;

public int getAge(){
return this.age;
}
}

Now I can call getAge() whenever to get the private variables value.
