Use Array.setShort and Array.setLong in Java

/*from   w w w.  j ava 2  s.  co  m*/
import java.lang.reflect.Array;

public class Main {
  public static void main(String... args) {
    Object o = new int[2];
    Array.setShort(o, 0, (short) 2); // widening, succeeds
    Array.setLong(o, 1, 2L); // narrowing, fails
  }
}
