Question

我一直收到错误＆＃34; Java错误不兼容类型：可能有损转换＆＃34;

我相信我可能需要设置更多变量，但我不太确定？

路线：

1）创建一个名为SavingsAccount

的公共类

2）将您的姓名和章节编号放在顶部的

块注释中

3）包含一个构造函数，该构造函数将所有者的名称和初始帐户余额作为参数。

4）包括帐户持有人姓名和帐户余额的私有非静态变量。

5）包括低利率和高利率的私有静态变量。

6）为帐户持有人姓名和帐户余额编写公共getter和setter方法。

7）为利率写一个公共的getter方法，如上所述计算。

8）包括低利率和高利率的公共静态getter和setter方法。

9）保存文件并确保编译。

import java.util.*;

public class SavingsAccount
{
    //private static and private nonstatic variables
    private String ownerName;
    private double acctBalance;
    private static double lowInt;
    private static double highInt;

    //write a public getter and setter for account holder
    public void setOwnersName(String name)
    {
        ownerName = name;
    }
    public String getOwnerName()
    {
        return ownerName;
    }
    //write a public getter and setter for the account balance
    public void setAcctBalance(double balance)
    {
        acctBalance = balance;
    }
    public double getAcctBalance()
    {
        return acctBalance;
    }

    //write a public getter method for interest rate
    public double getInterestRate()
    {
        if(acctBalance < 1000)
        {
            return lowInt;
        }
        if(acctBalance > 1000)
        {
            return highInt;
        }
    }

    //include public static getter and setter method for the lowe interest
    public static int setLowInt(double rate)
    {
        lowInt = rate;
    }
    public static int getLowInt()
    {
        return lowInt;
    }
    //include public static getter and setter for high interest
    public static int setHighInt(double rate)
    {
        highInt = rate;
    }
    public static int getHighInt()
    {
        return highInt;
    }

    public SavingsAccount(String name, double balance)
    {
        ownerName = name;
        acctBalance = balance;
    }
}//end class

您需要将返回转换为int

public static int getLowInt()
{
    return (int) lowInt;
}
