Dan's Q of Assertion?

[Vishy Karl]

Following is the Q from Dan's Exam

 
Question 16
class C {
  String m1(int i) {
    switch (i) {
      case 0: return "A";
      case 1: return "B";
      case 2: return "C";
      default: throw new AssertionError();
  }}
  public static void main(String[] args) {
    C c = new C();
    for (int i = 0; i < 4; i++) {
      System.out.print(c.m1(i));
}}}
Which statements are true? 
a.  With assertions enabled it prints ABC followed by an AssertionError message. 
b.  With assertions disabled it prints ABC followed by an AssertionError message. 
c.  Assertions should not be used within the default case of a switch statement. 
d.  In this code example an assert statement could not be used in place of the "throw" statement. 
 

Ans given are a,b,d.
Why is b also correct ?? If assertions r disabled then how will it show AssertionError message ?
TIA.
bye

It is just like any other error/exception and is not related to enabling or disabling of assertions. Enabling/Disabling of assertions will affect only those lines having the assert keyword followed by a boolean expression.
