emptying/clearing an array

public void removePlayers(Player[] client)
{
String G = "";
for (int i = 0; i < numPlayers; ++i)
{
G = G + client[i];
}
JOptionPane.showMessageDialog(null, G, "Player Info", 1);
}

i have set up this fubction as i want to clear all the data in the array. the info is all brought forward with the string and i want to be able to clear this wen sent back.

either code or a button that will be able to clear this will work. i have ran into so many walls and cannot solve it.

You can either make that method return (another) empty Player array (and have the caller of that method accept that, as in:

Code:

---

Player[] client= ...; // values in here
client= removePlayers(client);
...

Player[] removePlayers(Player[] client) {
  ...
  return new Player[numPlayers]; // return empty array
}

---

or you can wipe out all the elements of the existing array in your method:

Code:

---

void removePlayers(Player[] client) {
  ...
  for (int i= 0; i < numPlayers; i++)
      client[i]= null;
}

---

kind regards,

Jos

Code:

---

client = removePlayers(client,client.length);

---

Code:

---

   
public players[] removePlayers(players clients[],int length){

        for(int i=0;i<length;i++){
            clients[i] = null;
        }


        return clients;
    }
