親クラスの参照を持つ必要はなさそうなので static な方が良さそうです。
また、 final にしておくと完全に Immutable にできてばっちりですね:)

private final int uniqueSystemCount;
private final int uniqueDcfDrCdCount;

public DrCount(final int uniqueSystemCount, final int uniqueDcfDrCdCount) {
this.uniqueSystemCount = uniqueSystemCount;
this.uniqueDcfDrCdCount = uniqueDcfDrCdCount;
}

public int getUniqueSystemCount() {
return uniqueSystemCount;
}
public int getUniqueDcfDrCdCount() {
return uniqueDcfDrCdCount;
}
}
