Question

我正在尝试使用toString来显示帐号和余额，但没有成功。有人能帮我吗？谢谢

public class Account 
{

    double accountBalance;
    double deposit;
    double accountNumber;

    public Account(double initialDeposit) 
    {
    this.accountBalance = initialDeposit;
    this.accountNumber = 5; 

    }

    public String toString()
    {
        this.accountBalance;
        this.accountNumber;
    }
}

Answer 1

您需要将 @Override 添加到该方法并相应地设置余额格式。

@Override
public String toString()
{
    return "Balance on account number " + this.accountNumber +" is " + String.format("%1$,.2f", this.accountBalance); 
}
