Hi,

how can I make Locale output that the language of the passport is Russian, and for each element in the array list, to call the method isRussian();

public class Passport implements Comparable<Passport>{ 

    private  String firstName;
    private  String lastName;
    private Locale passportIssue;


// c-tor
public Passport(String firstName, String lastName, Locale passportIssue){ 

      this.firstName = firstName;
      this.lastName = lastName;
      this.passportIssue = passportIssue;

} 

//method
public boolean isRussian() { 

        If(passportIssue== "ru"){
                 return true;
           }
               return false;
    }

}

What I have tried:

List<Passport> pass= new ArrayList<>();Locale a= new Locale("ru");        

Passport p = new Passport("Erika",Ivanovich",new Locale("ru")); 

Passport p1 = new Passport ("Kemal", "Remzi", Locale.ENGLISH)


Passport p2 = new Passport ("Ivana",Bogdan",new Locale("ru"));

pass.add(p);
pass.add(p1);
pass.add(p2);

   System.out.println("Is the passport " + p.getPassIssue() + " russian? "
