I have a question about ArrayList
Example: I made a graphical interface in Java to register players in ArrayList . after registration, the player goes to a Jlist , then my question comes. I want to buy this player for my team, I select it and click on buy and in case this method buy I just used a remove. Would you like to remove it from the list of players that are for sale and put it on my Time ?
By logic, just as you have ArrayList "free" players, each Time object must have its ArrayList of players.
Consider this better ... think of a player's history, put a Contrato object in the middle, where you have the player id and team id, in addition to the start and end dates of the contract. >
You have some alternatives, among them:
Add the player you selected in ArrayList Time before you have removed it from ArrayList 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.*/);
}
