What a person owns the thing: Sara
What kind of stuff: Jewellery
What kind of jewelry: Necklaces

This is what i did so far:

public static void main(String[] args) {

    Scanner sc = new Scanner(System.in);
    ArrayList<Person> personList = new ArrayList<Person>();
    ArrayList<Pryl> prylList = new ArrayList<Pryl>();


    while (true){

    System.out.print("\n1: Skapa person \n2: Skapa pryl \n3: Visa alla \n4: Visa rikaste \n\n");
    int command = sc.nextInt();

      switch (command){

          case 1:
            System.out.print("Namn på person: ");
            String namn=sc.next();
            prylList.add(new Pryl(namn));
                 break;

          case 2:
              System.out.println("Vilken person äger prylen: ");
              String tempNamn=sc.next();

              for(Pryl x : prylList){
                  if(x.getNamn().equalsIgnoreCase(tempNamn)){
                      Person Person = new Person();
                      Person.setName(tempNamn);
                      System.out.println("Vilken sorts pryl: ");
                      String sortsPryl=sc.next();

                      if(sortsPryl.equalsIgnoreCase("smycke")){

                          System.out.println("Vilken sorts smycke: ");
                          String Sort=sc.next();

                          System.out.println("Antal ädelstenar: ");
                          int antal = sc.nextInt();
                          Person.setAntal(antal);
                          personList.add(Person);

etc...

		case 3:

               for (int x = 0; x < personList.size(); x++){
		Person tempPerson = personList.get(x);
                System.out.println(tempPerson.getName()+tempPerson.getSort()+tempPerson.getAntal());
                break;

               }
