Java vs Scala hashCode() and equals()

Conversion to scala from the java code :

@Override
    public int hashCode() {
	return new HashCodeBuilder()
		.append(alpha3Code)
		.toHashCode();
    }

    @Override
    public boolean equals(Object obj) {
	if (this == obj)
	    return true;
	if (obj == null)
	    return false;
	if (getClass() != obj.getClass())
	    return false;
	Iso639Language other = (Iso639Language) obj;
	return new EqualsBuilder()
		.append(alpha3Code, other.getAlpha3Code())
		.isEquals();
    }


Scala code :

    override def hashCode(): Int = Objects.hashCode(alpha3Code)
    override def equals(other: Any): Boolean = other match {
        case that: Language => this.alpha3Code == that.alpha3Code
        case _ => false
    }


(to be totally fair, Objects.hashCode comes from guava, so it could be used in the java code too)
