nullSafeHashCode	back to summary
public static int nullSafeHashCode(Object obj) Return as hash code for the given object; typically the value of `Object#hashCode()`}. If the object is an array, this method will delegate to any of the `nullSafeHashCode` methods for arrays in this class. If the object is `null`, this method returns 0.
