Olá pessoal nesse feriado resolvi criar um programa que gera chaves. Segue abaixo:

package principal;

import java.util.ArrayList;
import java.util.Random;

public class Metodos {

    private ArrayList<Object> alfaNum = new ArrayList();
    private String chave = "";
    private ArrayList<String> lista = new ArrayList();

    public ArrayList<String> getLista() {
        return lista;
    }

    public void listaParaSorteio(boolean c, boolean n, boolean s) {
        if (c == true) {
            for (char ch = ''A''; ch <= ''Z''; ch++) {
                alfaNum.add(ch);
            }
        }
        if (n == true) {
            for (int i = 1; i < 10; i++) {
                alfaNum.add(i);
            }
        }
        if (s == true) {
            alfaNum.add(''$'');
            alfaNum.add(''%'');
            alfaNum.add(''*'');
            alfaNum.add(''#'');
            alfaNum.add(''!'');
            alfaNum.add(''@'');
        }
    }

    public void gerarChave(int qtd, boolean c, boolean n, boolean s) {
        listaParaSorteio(c, n, s);
        Random r = new Random();
        for (int a = 0; a < qtd; a++) {

            for (int i = 0; i < 15; i++) { //Gera 15 caracteres
                if (i % 5 == 0 && i != 0) {
                    chave += " - ";
                }
                Object car = alfaNum.get(r.nextInt(alfaNum.size()));
                chave += car;

            }
            lista.add(chave);
            chave = "";
        }

    }
}
