5)	int i = 0; while (i a.size()) { return true; } return false;

Consider the following code:

public class MyClass { private int secret; public int getSecret(){ return secret; } }

Is the instance variable secret really private, meaning that it cannot be cannot be changed by client code? (2 points)

Question 28 options:

1)	Yes, because it is private.

2)	Yes, because it is private and non static.

3)	No, because getSecret() returns a reference to secret, which allows direct access to the instance variable.

4)	No, because getSecret() returns the value of secret, which can be changed by the client.

5)	No, because MyClass is a public class, and so its instance variables are all accessible by outsideclasses.
