# Error Prone

Error Prone is a static analysis tool for Java that catches common programming

mistakes at compile-time.

```java

public class ShortSet {

  public static void main (String[] args) {

    Set 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);

              ^

    (see https://errorprone.info/bugpattern/CollectionIncompatibleType)
