java - Using 1 variable for more values -

pretty new stuff , struggling problem... supposed create variable has many instances. example in case need ask user city of departure , city of arrival.

    system.out.println("vnesite ime mesta kamor potujete: "); // here ask first city      string mesto = scan.next();     system.out.println("vnesite ime države kamor potujete: ");     string drzava = scan.next();     system.out.println("vnesite ime mesta iz katerega potujete: "); //here ask second city     string mesto2 = scan.next();     system.out.println("vnesite ime države iz katere potujete: ");     string drzava2 = scan.next();       kraj kraj = new kraj(mesto, drzava); 

and here instances of variable should stored.

public class kraj {  private string kraj;  // variable supposed have many instances private string drzava;  public kraj(string kraj, string drzava) {     this.kraj = kraj;      this.drzava = drzava; }  public string getkraj ( ) {     return kraj;  }  public void setkraj (string kraj) {      this.kraj = kraj;  }  public string getdrzava ( ) {     return drzava;  }  public void setdrzava (string drzava) {     this.drzava = drzava;  } 

i've tried creating second variable, doesn't solve (what if traveler wants make stop @ destination in middle , proceed final destination). im looking explanation if possible not solution :)

thanks in advance guys/girls!

you can have a list of string store multiple destinations shown below:

public class kraj {     private list<string> kraj;//now stores multiple destinations     public list<string> getkraj() {      return kraj;     }     public void setkraj(list<string> kraj) {        this.kraj = kraj;     }     //add drzava , it's setters , getters  } 

so, in main code, need collect them array , pass shown below:

list<string> destinations = new arraylist<>(); system.out.println("vnesite ime mesta kamor potujete: ");     string mesto = scan.next();     system.out.println("vnesite ime države kamor potujete: ");     string drzava = scan.next();     destinations.add(drzava);     system.out.println("vnesite ime mesta iz katerega potujete: ");     string mesto2 = scan.next();     system.out.println("vnesite ime države iz katere potujete: ");     string drzava2 = scan.next();     destinations.add(drzava2);      kraj kraj = new kraj(mesto, destinations);
