IF Then Else Statement in eclipse in expression builder

In the output there are two language NLD and FRA. There is an if statement that i have been trying to make that if the language "bpp_langue_code" is FRA the results of the "bpa_ad_ville2" should be "Brussel" else the "bpa_ad_ville2" should be "Bruxelles".

But it's not working and showing no syntax error.

Below is my code:

if (row["BPP_LANGUE_CODE"] == "FRA") {
  (row["bpa_ad_ville2"] == "Bruxelles");
} else {
  (row["bpa_ad_ville2"] == "Brussel");
}

Any ideas? Thanks!
