   Correct, the answer is B. If the question's source code is executed, it will throw the following exception: - Exception in "main" thread java.lang.Error: Unresolved compilation issue: continue cannot be used outside of a loop The continue statement cannot be used outside of a loop, as described in the documentation. When commenting the continue statement line, the code compiles normally and then print "Thank You! 500.0" https://docs.oracle.com/javase/tutorial/java/nutsandbolts/branch.html To test: public static void main(String[] args) { int price = 1000; int qty = 2; String grade = "2"; double discount = 0.0; switch(grade) { case "1": discount = price * 0.1; break; case "2": discount = price * 0.5; //continue; default: System.out.println("Thank You!"); } System.out.println(discount); }
