Enabling Assertions

[Arnab Saha]

What should be the o/p:
public class Test {
public static void main(String[] args) {
int x = 0;
assert (x > 0): �assertion failed�;
System.out.println(�finished�);
}
}
Ans: Assertion thrown,or "finished".
If nothing is mentioned should we consider Assertion is disabled.

For java 1.5, I found assertions are disabled at run-time. You have to use switch '-ea' to enable assertions at run-time.

But at compile time, the assertions is treated as a keyword by default.

I want to know that if during Test of SCJP 1.4 if nothing is mentioned
what should we consider - Assertions enabled or Disabled.

[Rob Spoor]

Disabled. They are only enabled if explicitly mentioned.
