Beginning Java Quiz 4

The quiz below tests your knowledge of the material learnt in Beginning Java - Lesson 5 - Operators.

Question 1 : What values do a and b hold after the following expressions?

int a = 5; int b = 10; b = a++;
- a = 6 and b = 5 as the the postfix increment is applied after the expression is evaluated.
Question 2 : What symbol do we use for XOR (exclusive OR)?
- The ^ symbol is used for XOR (exclusive OR).
Question 3 : When could we use the || short-circuit operator?
- The || Short circuit operator can be more efficient when the first operand of an OR has a true value and therefore the OR criteria is met.
Question 4 : We can convert a boolean to an int using a cast?
- The boolean type is not only incompatible but also inconvertible with other types.
Question 5 : What is the result of a logical operator?
- The result of a logical operation is the boolean type.
Question 6 : Which code will work?
- C is the correct answer. We don't have to use the same type for the cast as long as the the cast is not widening. We will just get back the first 8 bits of the value.
