Which line will cause a compilation error?
public class Sample08
{
static boolean ready = true;
static void check()
{
assert ready;
}
public static void main(String[] args)
{
assert check();
}
}
Answer: D
check() is declared void, so it yields no value and cannot serve as the boolean condition of an assert. The assertion inside check() is fine. Either give check() a boolean return type or call it as an ordinary statement and assert on something else.
