Which line is an inappropriate use of an assertion?
public class Sample26
{
static
{
assert load() : "load failed";
}
static boolean load() { return false; }
public static void main(String[] args)
{
System.out.println("started");
}
}
Answer: B
Initialisation work must not depend on an assertion. With -ea the failing assertion escapes static initialisation as ExceptionInInitializerError and main never runs; without it load() is never called at all. Either way the class's readiness is decided by a debugging flag.
