Java Programming - Assertions - Discussion
Discussion Forum : Assertions - Finding the output (Q.No. 4)
4.
What will be the output of the program (when you run with the -ea option) ?
public class Test
{
public static void main(String[] args)
{
int x = 0;
assert (x > 0) : "assertion failed"; /* Line 6 */
System.out.println("finished");
}
}
Answer: Option
Explanation:
An assertion Error is thrown as normal giving the output "assertion failed". The word "finished" is not printed (ensure you run with the -ea option)
Assertion failures are generally labeled in the stack trace with the file and line number from which they were thrown, and also in this case with the error's detail message "assertion failed". The detail message is supplied by the assert statement in line 6.

Here,
x=0
And thus x is not greater than 0. So the condition is false.
So, how the answer is correct?

@Vivek.
If we want to execute assertion line then.
With the interpreter we should use -ea to execute assertion line of code.

What is -ea option? & what does -ea do?. mean javac is for compilation & java is for interpretation.
