Error Prone

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);
              ^
