Logical operators in "Section 4: Algorithm Design and Implementation"

Section 4: Algorithm Design and Implementation

states

...logical operators (limited to: !, &&, ||)...

Am I to understand that & and | ( simple logical operators, NOT short-circuit operators ) are excluded ?

Is there any Sun contact whom we can get clarification on this?

A sun contact sounds like a good plan but it seems they've purposely excluded the boolean logical operators for whatever reason. Probably to keep this "below" SCJP in terms of required knowledge as I think that is how Sun is setting this exam up to be...sort of a pre-exam to all the other certifications.

In that case Matt, they should have excluded short circuit operators ( &&, || ) and kept simple logical operators ( &, | ). In my experience with Java beginners, short circuit operators are more difficult to understand compared to simple operators.

My comment is, if you are already knew those topics, or if those topics are not really difficult to learn, why dont we also take a look on that?

At least, in order to play safe, we know how to answer those questions in case we see them in the test.

Exam-oriented is very important, however, the learning process is equivalently important as well.

Nick,

I know these topic, I am just curious to know why these are not part of exam objectives scope.

review everything you know including the exam objectives will safe your life for the scja exam.

I admit its been some time since I've had to distinguish between short circuit operators and simple logical but I understand your stance in that with simple logical operators both conditions are checked.

Now I'm trying to remember why I had such an easy time descerning this back in school because I recall the distinction came easy for me.

Probably came up with some "pavlovian" trick to tell the difference between short circuit and simple.

the lack of an edit feature is cumbersome

could it be to distinguish between the use of & and | for logic and bitwise operators and just to focus on them as conditionals?

In all cases where the exam objectives explicitly list things you need to know, it is safe to assume that you are being given a complete list.

In this particular case, only the most common operators were included on the exam.

Shift operators are not part of the exam or what?

True.

To quote myself...
