Which of the following command lines cause this program to fail on the assertion?
(Choose all that apply.)
public class On { public static void main(String[] args) { String s = null; assert s != null; } }
B, C.
Java uses the flags -ea or -enableassertions to turn on assertions.
-da or -disableassertions turns off assertions.
The colon indicates for a specific class.
Choice B is correct because it turns on assertions for all code.
Choice C is correct because it disables assertions but then turns them back on for this class.
