Java錯誤不兼容的類型：可能有損轉換？

Question

我不斷收到一個錯誤 「Java Error incompatible types：possible lossy conversion」

我相信我可能必須設置更多變量，但我不太確定？

路線：

1）創建）稱爲SavingsAccount

2 public類把你的名字和節號在註釋塊頂部

3）包含一個構造函數的參數所有者的姓名和初始帳戶餘額。

4）包含賬戶持有人名稱和賬戶餘額的私人非靜態變量。

5）包含低利率和高利率的私人靜態變量。

6）爲賬戶持有人姓名和賬戶餘額寫出公共的getter和setter方法。

7）爲利率編寫一個公共的getter方法，如上所述計算。

8）爲低利率和高利率包含公共靜態getter和setter方法。 9）保存文件並確保編譯完成。

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

你需要你的回報轉換爲int

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