What is the output of the following code?

b = 1;

while(b < 4)

System.out.print(b + " "); - ANSWER1 1 1 1 1 1...



Why? - ANSWERWhen b is 1, the comparison in the while statement is true, so 1 prints. The
comparison is made

again, it is still true (because b is still 1), and 1 prints again. The value 1 prints infinitely

because b is never altered.



What is the output of the following code?

b = 1;

while(b < 4)

{

System.out.print(b + " ");

b = b + 1;

} - ANSWER1 2 3



Why?? - ANSWERWhen b is 1, the comparison in the while statement is true, so 1 is output. Then b
becomes 2,

, the Boolean evaluation is still true, and 2 is output. The b becomes 3, the Boolean evaluation is

true and 3 is output. Then b becomes 4, the Boolean expression is false, and the loop ends.



What is the output of the following code?

e = 1;

while(e < 4);

System.out.print(e + " "); - ANSWERnothing



WHYY - ANSWERThe semicolon at the end of the second line creates an empty loop body. The value
of e remains

1 forever; it keeps being compared to 4 infinitely



If total = 100 and amt = 200, then after the statement total += amt, ___________. - ANSWERtotal is
equal to 300



whyyyy - ANSWERThe statement total += amt is equivalent to total = total + amt



The prefix ++ is a ___________ operator. - ANSWERa. unary



If g = 5, then after h = ++g, the value of h is ___________. - ANSWER6



If m = 9, then after n = m++, the value of m is ___________. - ANSWER10



why? - ANSWERThe variable n receives the value of m prior to incrementing



If j = 5 and k = 6, then the value of j++ == k is ___________. - ANSWERfalse



whyyyyyyyyyy - ANSWERThe value of j++ is 5, so it does not equal k. After this statement executes, j
will be 6, but that

will be after the value of this comparison has been determined.



You must always include ___________ in a for loop's parentheses - ANSWER2 semicolons
