Which line contains the error?
public class Sample23
{
public static void main(String[] args)
{
int size = 5;
assert size > 0;
assert size > 0;
System.out.println(size);
}
}
Answer: C
Both assertions compile and both pass, so the program is correct; nothing between them changes size. Repeating an identical check adds no information and misleads a reader into hunting for the difference. Assertions are documentation as much as verification, and duplicated ones read as an editing mistake.
