Question

Analyze the following code:

Code 1:

int number = 45;
boolean even;

if (number % 2 == 0)
even = true;
else
even = false;

Code 2:
int number = 45;
boolean even = (number % 2 == 0);

a. Code 1 has compile errors.
b. Code 2 has compile errors.
c. Both Code 1 and Code 2 have compile errors.
d. Both Code 1 and Code 2 are correct, but Code 2 is better.

What is the output from System.out.println((int)Math.random() * 4)?
a. 0
b. 1
c. 2
d. 3
e. 4

Given |x - 2| <= 4, which of the following is true?
a. x - 2 <= 4 && x - 2 >= 4
b. x - 2 <= 4 && x - 2 > -4
c. x - 2 <= 4 && x - 2 >= -4
d. x - 2 <= 4 || x - 2 >= -4

Given |x - 2| >= 4, which of the following is true?
a. x - 2 >= 4 && x - 2 <= -4
b. x - 2 >= 4 || x - 2 <= -4
c. x - 2 >= 4 && x - 2 < -4
d. x - 2 >= 4 || x - 2 < -4

What is the output of the following code?

boolean even = false;
System.out.println((even ? "true" : "false"));

a. true
b. false
c. nothing
d. true false
