ola pessoal
eu estou com uma duvida em como é que posso fazer o levantamente e deposito de contas.
Eu tenho o seguinte
um script que procura se a conta existe e retorna se existe ou nao. Agora eu queria que se ela existisse, que o user escreve-se tipo 3000? e ela levantasse. Só que eu estou tendo problemas com os estaticos e os getts and setters
o codigo é este
package sistema;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Iterator;
import java.util.List;
import java.util.Scanner;
public class Bank {
static List <Account> lista = new ArrayList<Account>();
public static void main(String[] args) {
// TODO Auto-generated method stub
showAll();
deposit1();
}
public static void deposit1() {
// TODO Auto-generated method stub
Scanner sc = new Scanner(System.in);
System.out.println("Digite o nome da conta:");
String find = sc.nextLine();
Account<?> ac = findByName(find);
if(ac == null) {
System.out.println("Account does not exist");
} else {
System.out.println("Found account! " + ac);
Scanner sc1 = new Scanner(System.in);
System.out.println("Digite a quantia a levantar:");
Double scan = sc1.nextDouble();
Account.withdraw(scan);
}
}
private static Account<?> findByName(String name) {
// TODO Auto-generated method stub
for(Account<?> ac :lista) {
if(ac.getAccountName().equals(name)) {
return ac;
}
}
return null;
}
public static void showAll() {
// TODO Auto-generated method stub
CurrentAccount conta1 = new CurrentAccount("Alberto Carlos", 1052);
CurrentAccount conta2 = new CurrentAccount("Pedro Fonseca", 30);
CurrentAccount conta3 = new CurrentAccount("Ricardo Vitor", 1534);
CurrentAccount conta4 = new CurrentAccount("João Lopes", 3135);
AccountLongTerm conta11 = new AccountLongTerm("Jacinto Alves", 54502);
AccountLongTerm conta12 = new AccountLongTerm("Ana Anabela", 30);
AccountLongTerm conta13 = new AccountLongTerm("Carlos Brás", 1234);
AccountLongTerm conta14 = new AccountLongTerm("José Fonseca", 545);
AccountP conta21 = new AccountP("Manuel Jose", 2200);
AccountP conta22 = new AccountP("Carla Costa", 3050);
AccountP conta23 = new AccountP("Francisco José", 12214);
AccountP conta24 = new AccountP("Alberto Teixeira", 31415);
Bank Bank1 = new Bank ();
Bank1.addAccount(conta1);
Bank1.addAccount(conta2);
Bank1.addAccount(conta3);
Bank1.addAccount(conta4);
Bank1.addAccount(conta11);
Bank1.addAccount(conta12);
Bank1.addAccount(conta13);
Bank1.addAccount(conta14);
Bank1.addAccount(conta21);
Bank1.addAccount(conta22);
Bank1.addAccount(conta23);
Bank1.addAccount(conta24);
Collections.sort(Bank1.lista);
System.out.printf("Bank Accounts:" + "%n");
Iterator<Account> itr = Bank1.lista.iterator();
while (itr.hasNext()) {
Account<?> element = itr.next();
System.out.printf(element + " " + "%n");
}
System.out.println();
}
public void addAccount(Account<?> conta) {
lista.add (conta);
};
}
e a minha conta por exemplo currentAccount é
package sistema;
class CurrentAccount extends Account<Object> {
public CurrentAccount(String accountN, double bal) {
super(accountN, bal);
// TODO Auto-generated constructor stub
rate = 0.01;
resultLong();
}
public String toString() {
return "Conta à ordem: " + getAccountName() + ", saldo " + balanceMoney.format(getBalance()) + "?" + ", Juros: " + decimals.format(resultLong) + "?";
}
@Override
public void deposit(double amount) {
// TODO Auto-generated method stub
}
@Override
public double withdraw(double amount) {
// TODO Auto-generated method stub
if (getBalance()-amount <0){
System.out.println("You don' have suficient founds!");
}
else {
setBalance(getBalance()-amount);
}
return getBalance();
}
}
sendo que na superclass tenho
package sistema;
import java.text.DecimalFormat;
abstract class Account<T> implements java.lang.Comparable<T> {
private String accountName;
private double balance;
protected double resultLong;
protected double rate;
public Account (String accountN, double bal) {
// TODO Auto-generated constructor stub
setAccountName(accountN);
setBalance(bal);
}
public int compareTo(Object o) {
// TODO Auto-generated method stub
if (this.getBalance() > ((Account<?>) o).getBalance()) {
return -1;
}
if (this.getBalance() < ((Account<?>) o).getBalance()) {
return 1;
}
return 0;
}
DecimalFormat balanceMoney = new DecimalFormat( " 0" );
DecimalFormat decimals = new DecimalFormat( " 0.00 " );
public double resultLong() {
return resultLong = balance*rate;
}
public void setBalance(double balance) {
this.balance = balance;
}
public double getBalance() {
return balance;
}
public void setAccountName(String accountName) {
this.accountName = accountName;
}
public String getAccountName() {
return accountName;
}
public abstract void deposit(double amount);
public abstract double withdraw (double amount);
}
pessoa agradecia mesmo muito a vossa ajuda
