Assume n is an int variable. Which Java expression is true exactly when n is an odd
number, i.e., not divisible by 2, and should be used to check for this situation? (hint: don't
forget negative numbers!)


*a.* n % 2 == 1
*b.* n % 2 != 1
*c.* n % 2 == 0
*d.* n % 2 != 0
*e.* none of the above - answer>>>d


Given the following code, which statement is true?


SimpleWriter out = new SimpleWriter1L( );
NaturalNumber n1 = new NaturalNumber1L(5);
NaturalNumber n2 = n1; n2.decrement( );

*a.* will output "n1 = 4, n2 = 4"

, *b.* will output "n1 = 5, n2 = 4"
*c.* will not compile

n.multiply(new NaturalNumber2(2));
if (n.compareTo(num) > 0) { num = n;
}
}
