Recently, I observed an unexpected behavior of accessing priavte fields in Java. Consider the following example, which illustrates the behavior:
public class A {
private int i; <-- private field!
public A(int i) {
this.i = i;
}
public void foo(A a) {
System.out.println(this.i); // 1. Accessing the own private field: good
System.out.println(a.i); // 2. Accessing private field of another object!
}
public static void main(String[] args) {
(new A(5)).foo(new A(2));
}
}
Why I am allowed to access the private field of another object of class A
within the foo
method (2nd case)?
