我在帐户类别中有以下方法
public void Transfer(int accountNo, double amount)
{
this.accountNo = accountNo;
double savingBal= this.getSavingBal();
if (this.savingBal > amount)
{this.savingBal=-amount;
this.checkingBal=+amount;
}
else
{
System.out.println("Insufficent fonds into savings account");
}
}
并将此代码放入Main Class:
//
Account b = new Account();
//
System.out.println("Please mention the amout you whish to transfer and the account");
amount = s.nextDouble();
accountNo = s.nextInt();
b.Transfer(accountNo, amount);
但是打印到控制台的结果始终是:
“资金不足”
请帮忙,
真诚的

//Scanner sc = new Scanner(System.in);

}
public Account(int accountNo, double checkingBal, double savingBal) {
this.accountNo = accountNo;
this.checkingBal = checkingBal;
this.savingBal = savingBal;
}
//makes a @Payment
public void Payment(double amount)
{
this.checkingBal=-amount;
}
//makes a @Deposit
public void Deposit(double amount)
{
this.checkingBal=+amount;
}
//makeks a transfer from @savings into @checking account
public void Transfer(int accountNo, double amount)
{
this.accountNo = accountNo;
double savingBal= this.getSavingBal();
if (this.savingBal > amount)
{this.savingBal=-amount;
this.checkingBal=+amount;
}
else
{
System.out.println("Insufficent fonds into savings account");
}
}
public void setCheckingBal(double checkingBal) {
this.checkingBal = checkingBal;
}
public void setSavingBal(double savingBal) {
this.savingBal = savingBal;
}
public int getAccountNo() {
return accountNo;
}
public void setAccountNo(int accountNo) {
this.accountNo = accountNo;
}
public double getSavingBal() {
return this.savingBal;
}
public double getCheckingBal() {
return this.checkingBal;
}
}
最佳答案
this.savingBal=-amount;
是错字,应该是
this.savingBal-=amount;
下一行也有类似的错字。这些可能是造成您的问题的原因。如果不是这样,并且存在另一个问题,那么如果您解决了另一个问题,它们将引起同样的问题。
