Java 我想不出下一步该怎么办

嗨，伙计们，我正在想办法让这个代码生成一个银行账户，但我余额的答案只有零，诸如此类，你能帮我吗。如果你想知道，我不允许输入

一揽子练习12

public class exercise12 {
    public static void main(String[] args) {
        Account myaccount = new Account(0, 0, 0, 0);
        System.out.println("my initial balance is " + myaccount.getBalance());

        System.out.println("depositing 32.19");
        myaccount.deposit(32.19);
        System.out.println("now my balance is " + myaccount.getBalance());

        System.out.println("withdrawing 90.00");
        myaccount.withdraw(90.00);
        System.out.println("now my balance is " + myaccount.getBalance());

        System.out.println("withdrawing 10.00");    
        myaccount.withdraw(10.00);
        System.out.println("now my balance is " + myaccount.getBalance());
    }
}
class Account {
    public Account (double a, double b, double c, double d) {
     deposit = a;
     withdraw = b;
     account = c;
     Balance = d;
   }

    public void deposit(double d) {
        // TODO Auto-generated method stub

    }

    Double Balance;
    Double withdraw;
    Double deposit;
    Double account;
    public void setmoney(double Balance, double withdraw, double deposit, double account){
        setBalance(Balance);
        setwithdraw(withdraw);
        setdeposit(deposit);
        setaccount(account);
    }
    public double getdeposit() {
        return deposit;
    }
    public double withdraw(double d) {
        return withdraw;
    }
    public double getaccount() {
        return account;
    }
    public double getBalance() {
        Balance = account - withdraw + deposit;
        return Balance;
    }
    public void setaccount(double accountmoney) {
    }
    public void setdeposit(double depositmoney) {
    }
    public void setwithdraw(double withdrawmoney) {
    }
    public void setBalance(double balancemoney) {
    }

}

您的

存款（）

和

取款（）

方法不会更改帐户中的余额。事实上，它们不会对

帐户

对象中的任何变量进行任何更改

构造函数只应设置期初余额

您不需要变量来存储

存款

和

取款

您的

存款（）

方法应将存款金额添加到余额变量中

您的

draw（）

方法应该从余额变量中扣除提取的金额

例如：

class Account {

    Double balance;
    Double account;

    public Account (final double accountNumber, final double initialBalance) {
       account = accountNumber;
       balance = initalBalance;
    }

    public void deposit(final double amount) {
        balance += amount;
    }

    public double withdraw(final double amount) {
        balance -= amount;
        return balance;
    }

    public double getAccount() {
        return account;
    }

    public double getBalance() {
        return balance;
    }

}

那么我如何让它工作呢？@user3666564访问字段。

+=

和

-=

操作符可能会有所帮助。我对java非常陌生，有人能复制我的代码并进行更改吗，因为我不知道我在做什么wrong@user3666564参见上文，请阅读帮助中心。另外，考虑使用调试器。
