How to test an add to list method with JUnit

I'm trying to test my add to list method using JUnit.

Here is my test method:

public int urunEkleTest(String marka, String urun) {
        UrunDepo depo = new UrunDepo();
        
        String urunekle = depo.urunEkle("Iphone","Apple");

But I have a error message with this test method

Error msg = The method urunEkle(Urun) in the type UrunDepo is not applicable for the arguments (String, String)

And my add to list method is :

public static List<Urun> urunEkle(Urun urun){
            URUNLER.add(urun);
            return URUNLER;
            
        }
