The following is a question from the pgjc - mock exam that i think has an incorrect answer.
1. Which of statements are true concerning the effect of the >> and >>> operators? a) for non-negative values of the left operand, the >> and >>> operators will have the same effect. b) the result of (-1 >> 1) is 0 c) the result of (-1 >>> 1) is -1 d) the value returned by >>> will never be negative as long as the value of the right operand is equal to or greater than 1 e) when using the >> operator, the left most bit of the bit representation of the resulting value will always be the same bit value as the leftmost bit of the bit representation of the left operand. the mock exam has the answer as A,D,E i think that the correct answer is A, E D is incorrect for example (-10 >>> 32) is still -10
The pgjc exam also has the following question. Which are valid identifiers. a) class b) $value$ c) zer@ d) angstrom e) 2much it has the answer as being A,B,D but class is a reserved word so it can not be used as an identifier
Hi Macha, The answer d of your first question in my book is d) The value returned by >>> will never be negative as long as the value of the right operand is not divisible by 32. So the answer d is correct. The answer a of your second question in my book is a) _class So the answer a is also correct.
The questions are from the pgjc mock exam application. I guess they fixed the questions in the book (mine is the same as you said) but they did not correct the exam engine that is on the website. thanks
