GitHub - google/error-prone: Catch common Java mistakes as compile-time errors (original) (raw)

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 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);
