I have a question about Arraylist

Example: I made a graphical interface in Java to register players in a ArrayList. after registration, the player goes to a Jlist, Here comes my doubt. I want to buy this player for my team, I select it and click on buy and in case this method buy I only used a remove. I wanted to remove him from the list of players for sale and put him in mine Team?

You have some alternatives, among them:

  • Add the player you selected to Arraylist Time before having it removed from the Arraylist of players for sale:

    public class Time {
    private ArrayList<Jogador> time; //ArrayList do seu time.
    public Time() {
        time = new ArrayList<>();
    } public adicionarJogador(Jogador a) {
        time.add(a);
    }
}
//
public class Vendedor {
    private ArrayList<Jogador> vendavel; //ArrayList de jogadores à venda, supondo que já existem jogadores nesse ArrayList.
    Time a = new Time();
    public venderJogador() {
        a.adicionarJogador(/*Índice do jogador que você selecionar através da interface.*/);
        vendavel.remove(/*Índice do jogador que você selecionar através da interface.*/);
    }

    ...

Logically, the same way you have a ArrayList of "free" players, each object Time have to have your ArrayList of players.

Take a closer look at this... think of a player history, place an object Contrato in the middle, where you have the player id and the team id, as well as the start and end dates of the contract.
