Answer A: Result 3

compilation fails for semicolon minsing

D is correct, array cannot assign by ("element")

Correct answer is: Compilation fails. String days[] = ("sun", "mon", "wed", "sat"); there must be { } not ()

answer is A, is tested : int wd = 0; String days[] = {"sun", "mon", "wed", "sat"}; for (String s : days) { switch (s) { case "sat": case "sun": wd--; System.out.println(wd + " sun "); break; case "mon": wd++; System.out.println(wd + " mon "); case "wed": wd += 2; System.out.println(wd + " wed "); } } System.out.print(wd + " "); result is -1 sun 0 mon 2 wed 4 wed 3 sun 3

Answer is A

The answer is D, the array parentheses were instantiated wrong, it's "{}" instead of "[]".

The array instantiation is wrong, it is {} instead of [] and this causes a compilation error. If the array was with {} it would compile. So the answer is letter D.

Correct Answer is B. Since there is no break statement for "mon" it will execute next case statement also

if we consider that the parenthesis in array 'days' is a typo, then the answer is A. Else the ans would be D

Answer is D. there should be curly braces instead of parentheses

Testing in my IDE, the answer that most convinces me is the letter D. An error occurs in the attribution signal. When I remove the parentheses and insert braces the error disappears

Answer is A

Correct answer A

Correct answer is A, result is 3 public class Test { public static void main(String[] args) { int wd = 0; String days[] = {"sun", "mon", "wed", "sat"}; for (String s : days) { switch (s) { case "sat": case "sun": wd--; break; case "mon": wd++; case "wed": wd = wd + 2; } } System.out.print(wd + " "); } }

After correcting the parentheses () around the array values {should be curly brackets} Result is 3. Tested in IntelliJ.
