Error Prone is a static analysis tool for Java that catches common programming mistakes at compile-time.
public class ShortSet {
public static void main (String[] args) {
Set<Short> s = new HashSet<>();
for (short i = 0; i < 100; i++) {
s.add(i);
s.remove(i - 1);
}
System.out.println(s.size());
}
}
error: [CollectionIncompatibleType] Argument 'i - 1' should not be passed to this method;
its type int is not compatible with its collection's type argument Short
s.remove(i - 1);
