包含字符串数组列表的数据结构

Question

I do not know which data structure should I use to implement something like this:

data = {"name", "surname", "age", //listOfFriend {"Jon", "Sansa", "Arya", "Ramsay"}}

I was thinking about this: public ArrayList<ArrayList<String[]>> listaInterventi = new ArrayList<>(); but I'm not sure. Can you help me?

Answer 1

You could have a class, Person, with name, surname, and age fields as well as an ArrayList field for friends.

public class Person {

    String name;
    String surname;
    int age;

    List<String> friends;

    public Person(String name, String surname, int age, List<String> friends) {
      this.name = name;
      this.surname = surname;
      this.age = age;
      this.friends = friends;
    }    
}

List<String> friends = new Arraylist<String>();
friends.add("Chicken");
friends.add("Weedwacker");
friends.add("CornCob");
Person person = new Person("Name", "Surname", 42, friends);
