QUESTION 1

In Java a block of code (a group of statements) is enclosed in?

		any of these will do
		braces {}
		parentheses ()
		brackets []

QUESTION 2

Assume that a and b are two declared and initialized variables of type double. Consider the following line of Java code:

int c = (int) a / b;

Which variable(s), if any, will explicit casting be applied to in this expression?

		a
		b
		Neither a nor b
		Both a and b

QUESTION 3

Consider the following Java identifier:

STATUS

Following the naming convention suggested in lecture slides, what is STATUS most likely going to represent?

		This is not a valid identifier
		A constant
		A class name
		A method name

QUESTION 4

Assume that a and b are two declared and initialized variables. Variable a is of type double. Variable b is of type int. Consider the following line of Java code:

b = a;

What kind of type casting, if any, is necessary here?

		Explicit casting
		Implicit casting
		Both implicit and explicit casting
		There is no need for casting at all

QUESTION 5

Consider the following line of Java code (you can assume that there are no errors here):

k = (Math.PI + x) * 4.56;

Which part of this expression is considered to be a literal?

		Math.PI
		4.56
		x
		k

QUESTION 6

Consider the following line of Java code:

float h = Math.E * 123.45;

What primitive data type Java will assume 123.45 is?

		double
		long
		int
		float

QUESTION 7

Assume that pies and people are two declared and initialized variables of type int. Also, assume that piesPerPerson is a declared and initialized variable of type float. Consider the following line of Java code (This line has issues, BTW. Think why):

piesPerPerson = (float)(pies/people);

What Java operations are involved here?

		variable declaration, implicit casting, integer division
		variable declaration, explicit casting, integer division
		variable assignment, explicit casting, integer division
		variable assignment, implicit casting, integer division

QUESTION 8

Which identifier is illegal in Java?

		broke
		break
		broken
		brake

QUESTION 9

What is modulo operation doing in Java?

		It returns a result of a division operation
		It rounds a floating point number to the nearest integer greater than that floating point number
		It returns a remainder of a division operation
		It returns a fractional/decimal part of a floating point number

QUESTION 10

Assume that a and b are two declared and initialized variables. Variable a is of type double. Variable b is of type int. Consider the following line of Java code:

a = b;

What kind of type casting, if any, is necessary here?

		There is no need for type casting here at all
		Explicit casting
		Implicit casting
		Both implicit and explicit casting
