About Question enthuware.ocajp.i.v7.2.922 :

[Javanaut]

Found another error - The explanation for this problem says that an object is created on line 8 with the same parameters when it is actually created on line 7

[admin]

You are right, it should be 7. This has now been fixed.

thank you for your feedback!

[Javanaut]

I think I have found 3 errors now. Do I qualify for the money-back ?

I really like this program and the forum. It is fun to help out even if I am not monetarily rewarded, though I was fired recently.

[dtchky]

Myself as well, though I do not actually want my money back since I think the application is tremendously valuable regardless.

Thanks, we share the same outlook on value, certification exam for me next week. I've spent at least a couple of hundred hours taking (and retaking) all the enthuware tests, $10 plus some good feedback karma in return for a passing grade on the OCAJP, this adds a pretty important dot point on my resume, so I think I'd definitely pay a lot more for it just the way it is right now : )

Cheers.

It is assumed that "there is a Student class with appropriate methods", but the implementation may be any. For example:

Code: Select all

class Student {
	public static Student lastInstance;
	
	public Student(String name, String no) {
		this.lastInstance = this;
	}

	public void grade() {}

	public String getName() {return null;}
}

And with this realization the answer is not "Line 6". What do you think?

[admin]

It says "appropriate", not "any" Do you think returning null from a getter method is an appropriate implementation?

[exiart]

The point is not that my implementation is incorrect. I can make the correct, appropriate. I want to draw attention to the line in my code:

Code: Select all

this.lastInstance = this;

And after line6 (s=null), the object originally held in s, may NOT be garbage collected.

Ok) I understand you and I have to think easier

[admin]

OK, the question has now been updated to include implementation for Student class methods to avoid such confusion.

thank you for your feedback!
